Cross-Cultural Differences in Perception of Facial Trustworthiness Based on Geometric Morphometric Morphs

We report on an experimental study that explores cross-cultural differences in perception of trustworthiness based on facial traits. In the first part of the experiment, individual male and female neutral photographs of Buryats (Mongolian people of Eastern Siberia) were rated on trustworthiness by men and women from the same population. The trustworthy-looking facial traits were investigated by means of geometric morphometrics, and analysis of the facial action units using artificial neural network (FaceReader). Significant associations between facial traits and perceived trustworthiness were revealed only for male photographs rated by men. Facial shape pattern along trustworthy–untrustworthy vector corresponded to the facial femininity-masculinity vector for Buryats, as well as to the positive-negative vector of the emotional connotation of the neutral facial shape. “Untrustworthy” facial shape was characterized by relatively narrower lower jaw, lower set eyebrows, as well as a lower position of the “Brow Lowerer” facial action unit—a frown. In the second part of the experiment, two geometric morphometric morphs, representing “trustworthy” and “untrustworthy” Buryat male facial shapes, were judged on trustworthiness by male representatives of Buryat, Tuvan (Mongolian people of Southern Siberia), Russian, Indian, and East African (Tanzanians) cultures. The results revealed that in all studied samples the “trustworthy” male portrait was rated significantly higher on trustworthiness than “untrustworthy” one. However, perceived trustworthiness, and agreement of portrait judgments with those of Buryats significantly declined with geographic and genetic distance between populations.

The Genus Heterogynis Rambur, 1866 (Heterogynidae, Lepidoptera): Congruence of Molecular, Morphological and Morphometric Evidence Reveal New Species in Serbia

The Heterogynidae are a small family of moths consisting of a single genus Heterogynis and sixteen described species distributed in the Mediterranean region. A species new to science, Heterogynis serbica sp. nov., is described from the locality of Srebrenac, Mt. Kopaonik, Republic of Serbia, Balkan Peninsula, by applying an integrative taxonomic approach using morpho-anatomical characteristics, wing morphometics and DNA barcoding. Male genitalia, scanning electron micrographs of adult male head anatomy, abdominal tergites/sternites, cocoons and habitats of the closely related species H. serbica sp. nov. and H. zikici are discussed and illustrated. Photographs of adult males and females, cocoons, plants in which the cocoons were found and habitats are shown. Importantly, marked differences in genital structure and other morphological characters were noted. These differences were confirmed with forewing morphometrics and COI-based DNA barcoding results. Additionally, DNA barcodes for H. serbica sp. nov. and H. zikici were compared against previously available data for the genus to evaluate the phylogenetic relationships. We conclude that deep, previously unknown and unexpected intrageneric morphological diversity exists in the genus Heterogynis.

Maria Morris Hambourg: A Curator Lighthouse for Photography

Founding curator of the Metropolitan Museum of Art’s Department of Photographs, Maria Morris Hambourg’s impact on the field of photography is incalculable. Across a multi-decade career, Hambourg influenced the canon of photography through largely monographic exhibitions. I use the terms searchlight and lighthouse as metaphors to describe her influence on curation and scholarship as well as the passion that focused her in-depth research. Hambourg’s interest in the print process and photographic papers in tandem with historical context has been an important model for the generations of photography historians and curators that succeeded her. A committed expert on nineteenth-century France, Hambourg built relationships with photography collectors and conducted material and biographical research on artists such as Eugène Atget, Nadar and Gustave Le Gray. Acknowledging her focus on European, white male photographers, I position Hambourg’s exhibitions and writing as an important foundation for later research and scholarship that more thoroughly untangles histories of power, race and class, within the same canon she helped construct.

A Taxonomic Revision of the Dichotomius reclinatus (Felsche, 1901) Species Group (Coleoptera: Scarabaeidae: Scarabaeinae).

The taxonomic revision of the Dichotomius reclinatus species group (Coleoptera: Scarabaeidae: Scarabaeinae: Dichotomius Hope, 1838) sensu Arias-Buriticá and Vaz-de-Mello (2019) is presented. The group comprises four species previously included in the Dichotomius buqueti species group: Dichotomius horridus (Felsche, 1911) from Brazil, French Guiana, and Suriname; Dichotomius nimuendaju (Luederwaldt, 1925) from Bolivia, Brazil, and Peru; Dichotomius quadrinodosus (Felsche, 1901) from Brazil; and Dichotomius reclinatus (Felsche, 1901) from Colombia and Ecuador. A definition of the D. reclinatus species group and an identification key are presented. In the key we included to Dichotomius camposeabrai Martínez, 1974, this species due the external morphology can be confused with the D. reclinatus species group and for the first time photographs of males and female of this species are presented. For each species of the D. reclinatus species group, the following information is provided: taxonomic history, citation of the species in published literature, redescription, list of material examined, photographs of the external morphology, illustrations of male genital organs and the endophallites, and distribution map.

Is There Gender Bias in Perceptions of Strabismus Among Adults?

To investigate the effect of gender, type, and size of horizontal deviation on the perceived severity or need for intervention for strabismus among adults in the general population. Eight photographs of individuals aged 25 to 35 years were digitally manipulated to create 30 prism diopters (PD) of exotropia, 30 PD of esotropia, 50 PD of exotropia, and 50 PD of esotropia in both men and women. A survey asked respondents to rank these photographs by their severity or need for intervention from 1 (greatest need) to 8 (least need) to assess for unconscious bias for gender, strabismus type, or deviation size. A total of 203 adult respondents completed the survey. Participants ranked men with both large esotropia and large exotropia (median rank = 1.5, interquartile range [IQR] = 1.5 to 1.5) as needing correction more urgently than similar women (median rank = 3.5, IQR = 3.5 to 4) (P < .0001). The median rank was 4 (IQR = 3.75 to 4.25) for all men combined and 5 (IQR = 4.75 to 5.25) for all women (P < .0001). Photographs with exotropia (median rank = 4, IQR = 3.75 to 4.5) were perceived as more severe than photographs with esotropia (median rank = 5, IQR = 4.5 to 5.25) (P < .0001). Respondents' gender, age, or history of strabismus did not significantly impact their rankings. Male photographs were perceived as having a greater need for strabismus intervention than female photographs despite similar type and size of deviations. Exotropia was perceived as more severe than esotropia for smaller deviations only. More studies on the perceptions of strabismus are needed to understand whether unconscious bias affects patient care. [J Pediatr Ophthalmol Strabismus. 2023;60(6):396-401.].

A new species of the genus Megatachycines (Rhaphidophoridae: Aemodogryllinae: Aemodogryllini) from Guizhou, China.

Zhu et al. (2022) proposed the genus Megatachycines based on the description of a new species and the reviewed genus Microtachycines. In this study, a new species of Megatachycines, namely Megatachycines rectangularis sp. nov., from Guizhou Province, China is described. This new species is similar to Megatachycines elongatus, and the morphological differentiation between the two species is discussed. Morphological information including diagnosis of the new species, description of male genitalia, and some related photographs of males and females are provided.

A pictorial key for identification of the hoverflies (Diptera: Syrphidae) of the Madeira Archipelago.

Syrphid flies are important ecological indicators and provide crucial ecosystem services, being important pollinators and biological control agents of insect pests. These charismatic insects are conspicuous and, due to their size and colourful patterns, are relatively easy to identify. However, the lack of user-friendly literature (e.g. photographic guides) for most areas may hamper its wider selection as a study group in biodiversity and ecological studies. The syrphid fauna of Madeira Archipelago comprises 26 species, including four endemics (Eumerushispidus Smit, Aguiar & Wakeham-Dawson, 2004; Melanostomawollastoni Wakeham-Dawson, Aguiar, Smit, McCullough & Wyatt, 2004; Myathropausta, Wollaston, 1858 and Xanthandrusbabyssa, Walker, 1849), but, despite the current good taxonomic knowledge on this group, information on species distribution, ecology and conservation is still lacking. Here, we provide a pictorial key to the adult hoverflies of Madeira Archipelago highlighting diagnostic characteristics and present photographs of both males and females (in dorsal and lateral views) in colour plates. The key and plates will help researchers to differentiate these species, thus encouraging the use of this insect group in future bioindication studies. In addition, this study also aims to engage a broader audience of non-experts in improving the knowledge on the distribution and ecology of Madeira syrphids. We provide a checklist for the hoverflies of Madeira Archipelago and a pictorial key to help on species identification.

The influence of malocclusion on social aspects in adults: study via eye tracking technology and questionnaire

BackgroundSmile esthetics has a strong influence on perception, attractiveness, and personal characteristics. It is unknown how malocclusions may influence the appearance of the individual's smile. This study aimed to investigate whether malocclusion affects the visual perception of esthetics, age, employability, honesty, intelligence and to meet its obligation in time in middle-aged adults. Facial frontal smiling photographs of a male and a female middle-aged adult with 3 different malocclusions were shown to and evaluated by 90 laypeople (non-dentists), divided into groups: young adults (14–44 years), middle-aged adults (45–59 years), and elders (over 60 years). The index of treatment need (IOTN) was used, and IOTN 1, 5, and 8 images were created in Photoshop using the male and female photographs. In total, 6 photographs were evaluated, 3 areas of interest (AOI)—eyes, nose, and mouth—were created for statistical comparison. The Ogama and Eye Tribe tracker were used in conjunction to measure eye tracking. A visual analog scale (VAS) was employed with a questionnaire surveying individuals’ perception of age, employability, honesty, intelligence, and ability to meet obligations. Kruskal–Wallis, one-way analysis of variance, Pearson’s—chi-squared, and Pearson correlation test were applied.ResultsNo statistical difference was found in complete fixation time and time until the first fixation for each AOI for eye-tracking. VAS showed statistical differences in the male and female IOTN 1 images when compared with the IOTN 5 and 8 for both models, and there was no difference between genders in the IOTN 1. As the perceived age of the model increased, the chances of getting hired decreased. Employability, honesty, intelligence, and ability to meet obligations showed higher values for IOTN 1. There were significant differences between age ranges; perception of intelligence in the female IOTN 1 model (p = 0.002) and IOTN 8 model (p < 0.001) and honesty between young adults and middle-aged adults in the male IOTN 1 and 8 images (p < 0.001).ConclusionsThere was a difference between age groups in the perception of honesty and intelligence. A well-balanced and attractive was perceived as more youthful and attractive in both genders and may increase the chance of being selected for a job interview or being hired.

Revision, morphometry and cladistics of Erynephala (Coleoptera: Chrysomelidae: Galerucinae: Galerucini)

The genus ErynephalaBlake, 1970 is reviewed based on linear morphometry and a morphological study. A cladistic analysis of the genus based on morphological characters is also presented. The results demonstrate that Erynephala brightiBlake, 1970 is synonym of Erynephala maritima (LeConte 1865), and that the “race” of E. maritima, originally described as Monoxia puncticollis var. texanaSchaeffer, 1932 is recognized as a different species: Erynephala texana (Schaeffer 1932) stat. nov.. The cladistic analyses revealed that Erynephala is monophyletic, forms three clades: ((E. maritima + E. texana) + (Erynephala morosa + Erynephala puncticollis)) + Erynephala interrupta, and it is close related to MonoxiaLeConte, 1865 species. We also provide redescriptions and photographs of adult males and females, in addition to distribution maps.

Only Eye Candy? Original Plumbing Magazine’s Remodeling of the (Trans) Male Pin-Up

The participation of trans masculine models and photographers in the visual economy of pin-ups is particularly evident across the ten years and twenty issues of Original Plumbing (OP), helmed by coeditors Amos Mac and Rocco Kayiatos. Steinbock proposes that as “eye candy” that serves up a visual treat and seems intellectually undemanding, these trans male pin-ups have sweet-talked their way into a hostile phallic economy, and a community into seeing themselves as sexually desirous. In doing so, the notable invisibility of the eroticism of trans men, FTMs, nonbinary masculine folks, genderqueers, and more has been reversed. The pin-up, with its cheesy yet celebrity-chic conventions, can upend what Steinbock summarizes as the “phallic economy of the gaze.” Trans male models have much to teach visual culture scholars about arriving on the scene of visuality in ways that circumvent the binary of the active/masculinized look and the passive/feminized gazed-upon body. Through comparisons with cheesecake, beefcake, publicity shots, and nudes, the article demonstrates how OP remodeled conventions of masculine posturing, heterosexual assumption, and pop culture grammars. Further, Steinbock attends to the ways in which heterosexual masculinity is imbricated with whiteness, youth, and muscularity, a phallic paradigm that is critically reframed by the collaborative labor of trans male photographers and models.

The impact of tooth colour on the perceptions of age and social judgements.

ObjectivePsychological research has established that the presence of dental anomalies negatively impact social judgements. This study sought to determine the effects of tooth colour on the subjective ratings of social judgements in a group of Caucasian adults. MethodsA cross sectional experimental analogue design comprised fifty Caucasian adults: 25 women and 25 men. A total of 54 digitally modified photographs of Caucasian males and females (darkened, natural, whitened teeth) were evaluated. All participants evaluated each of the images on 12 characteristics: popularity, friendliness, social life, success, graduation, happiness, intelligence, perceived age, introversion/extraversion, self-confidence, attractiveness and satisfaction with the tooth shade. Analysis of variance (ANOVA) was used to compare ratings. ResultsParticipants associated darkened teeth with poorer subjective ratings, with the highest ratings been given to whitened teeth, and natural teeth being intermediate. These trends were similar across all participant age groups and gender. Further, the gender and age groups of the images had a significant effect on the appraisals. Faces of younger models received higher ratings than the faces of older models and female images were rated higher than the males. ConclusionIn the absence of other information, tooth colour exerts an influence upon the appraisals made in social situations. It appears that whitened tooth appearance is preferred to natural tooth appearance, irrespective of age and gender of the judge. The faces with more whitened dentition are perceived to be younger across all age groups and gender of the judges. Participants dissatisfied with their own tooth shade drew out more stereotypic behaviour. Clinical significance statementThis research used standardised tooth colour as a basis to investigate perceived age and social functioning. As clinicians face daily challenges to achieve patient satisfaction with respect to dental aesthetics, standardizing the colour may enhance the patients’ satisfaction. Further, participants dissatisfied with their own tooth shade drew out more stereotypic behaviour. The whitened dentition may impair the psychological well-being of the individuals and is probably a reason for the increasing demand for cosmetic dental procedures. These results may be instructive for the development of a psycho-educational intervention to prevent any unrealistic expectations.

Tokiwa Toyoko, the nude shooting session, and the gendered optics of Japanese postwar photography

For the first decade after the end of World War Two, nūdo satsueikai (nude shooting sessions in which naked female models were photographed by groups of primarily male photographers in public parks, beaches, and studios) offered a particularly popular way to engage in photography in Japan. Photographer Tokiwa Toyoko was one of the many women entering male dominated workplaces in this period and through her portrayal of the male participants at the nude shooting session she critiqued assumptions that women were more suited to being in front of, rather than behind, the lens of the camera. The following article pursues a detailed analysis of mass media depictions of the so-called ‘birth of the female photographer in postwar Japan’ and intervenes in debates surrounding nude shooting sessions to provide a new interpretation of Tokiwa’s photographs of women who labored with their bodies. In so doing, it calls into question the foundational discourses of Japanese postwar photographic realism and reveals a new perspective on the gendered dynamics therein.

Revision of the Afrotropical genus Fainia Zumpt, 1958, with notes on the morphology of Rhiniidae subfamilies (Diptera, Oestroidea).

The taxonomy and diversity of Fainia Zumpt, 1958, an exclusive Afrotropical genus, had not been reviewed recently. The genus included six nominal species, but the status of several of them was debated. Identification of most Fainia species depends on characters of the male terminalia; females are poorly known and, in several cases, are not adequately diagnosed. We conducted a taxonomic revision of the genus and generated identification tools. Based on the study of type material and specimens available in entomological collections in Africa and Europe, we recognise here three of the six species as valid (F. albitarsis (Macquart, 1846), F. elongata (Bezzi, 1908) and F. inexpectata Zumpt, 1973). We also provide an identification key to both sexes, redescriptions of the species, updated distribution records and high resolution photographs of males’ and females’ habitus and male terminalia. The description of Fainia kagerana Lehrer, 2007a nom. nud. is an invalid nomenclatural act in terms of ICZN Article 13.1.1. Based on examinations of their holotypes, F. sambura Lehrer, 2008 syn. nov. is proposed as a junior synonym of F. albitarsis; F. kirinyaga Lehrer, 2007b syn. nov. is proposed as a junior synonym of F. inexpectata; and Fainia giriama Lehrer, 2007b is moved from the genus Fainia to the genus Rhinia Robineau-Desvoidy, as Rhinia giriama (Lehrer, 2007b) comb. nov.. We propose two apomorphies that support the status of the subfamily Rhiniinae.

Optical Survey: Anthropocenean Consciousness of the Photographic Image

Early forms of photography play a unique role in establishing an Anthropocenean consciousness in the mid-nineteenth century that witnesses human relationships with nature as exclusively transactional, by centring its focus on the violent displacement of people from their contexts simultaneous to the violent displacement of objects from their contexts. Such practices of perception were co-constituted with other forms of excessive violence that eventually became unique to the geography of the American West. By photographing Native Americans as objects, white American male photographers were able to transform them into relics, and in so doing, cast the Indigenous cultures from which they were drawn as fundamentally dead, turning the enemy figuratively into the past, and practically into oblivion to the degree that it is possible for institutions to confine them to ‘natural’ history through the twinned force of taking both object and image from them. It was, therefore, not so much a case of designating colonised populations, as designing them aesthetically so that they fit in a material sense of belonging to an order greater than themselves. Violence in this sense becomes a relational project to how we understand mankind itself and its origins in a racial science that allowed for this living body of photography to enter in and make itself known as both a witness and a trace of the past generating whole environments through which such systems of knowledge could and did endure to our present moment.

Was facial width-to-height ratio subject to sexual selection pressures? A life course approach.

Sexual selection researchers have traditionally focused on adult sex differences; however, the schedule and pattern of sex-specific ontogeny can provide insights unobtainable from an exclusive focus on adults. Recently, it has been debated whether facial width-to-height ratio (fWHR; bi-zygomatic breadth divided by midface height) is a human secondary sexual characteristic (SSC). Here, we review current evidence, then address this debate using ontogenetic evidence, which has been under-explored in fWHR research. Facial measurements were collected from 3D surface images of males and females aged 3 to 40 (Study 1; US European-descent, n = 2449), and from 2D photographs of males and females aged 7 to 21 (Study 2; Bolivian Tsimane, n = 179), which were used to calculate three fWHR variants (which we call fWHRnasion, fWHRstomion, and fWHRbrow) and two other common facial masculinity ratios (facial width-to-lower-face-height ratio, fWHRlower, and cheekbone prominence). We test whether the observed pattern of facial development exhibits patterns indicative of SSCs, i.e., differential adolescent growth in either male or female facial morphology leading to an adult sex difference. Results showed that only fWHRlower exhibited both adult sex differences as well as the classic pattern of ontogeny for SSCs—greater lower-face growth in male adolescents relative to females. fWHRbrow was significantly wider among both pre- and post-pubertal males in the Bolivian Tsimane sample; post-hoc analyses revealed that the effect was driven by large sex differences in brow height, with females having higher placed brows than males across ages. In both samples, all fWHR measures were inversely associated with age; that is, human facial growth is characterized by greater relative elongation in the mid-face and lower face relative to facial width. This trend continues even into middle adulthood. BMI was also a positive predictor of most of the ratios across ages, with greater BMI associated with wider faces. Researchers collecting data on fWHR should target fWHRlower and fWHRbrow and should control for both age and BMI. Researchers should also compare ratio approaches with multivariate techniques, such as geometric morphometrics, to examine whether the latter have greater utility for understanding the evolution of facial sexual dimorphism.

Armed with a Camera: Gender, Human Rights, and Visual Documentation in Israel/Palestine

This article offers an explanation for the use of the documenter’s gender as part of human rights politics. I examine the case of the Camera Project of B’Tselem, an Israeli human rights organization working in the Occupied Palestinian Territories. The organization, which distributes video cameras to Palestinian residents, celebrates the participation of women in the documenting project and declares that the women’s videos capture a unique point of view. In the article I question why the gender of a given witness would be emphasized as essential since there is no clear distinction in the visual outcome—that is, in the videos—between those taken by female and male photographers. I analyze visual material from the project and combine this examination with interviews with Palestinian women photographers, all of which reveals that their gender identity is not crucial to the message that the videos try to impart about Israel’s occupation. Drawing on critical feminist scholarship on the gendering of warfare and international law, I argue that preexisting cultural ideas about gender affect the organization’s strategic framing process.

Defining Aesthetic Preferences for the Penis: A Photogrammetric and Crowdsourcing Analysis.

Achieving an aesthetic phalloplasty result is important for patients with acquired or congenital defects of the penis, or with genital-related dysphoria. However, aside from length and girth, the aesthetic proportions of the male penis have not been defined. This study aimed to determine proportions of the male penis through photogrammetric analysis of nude male photographs and to verify these proportions with a crowdsourcing-based survey. Nude male photographs (n = 283) were analyzed to define aesthetic proportions of the male penis. Photographs were analyzed for the position of the penis on the torso in relation to the umbilicus and for the ratio of the dorsal and ventral glans of the penis in relation to the entire shaft length. Proportions were then further studied by crowdsourcing 1026 respondents with Amazon mechanical Turk. The ideal position of the penis below the umbilicus is about 55% (6/11th) of the distance from the jugular notch to the umbilicus (measured average, 53.6%; survey-weighted average, 58.9%). The dorsal glans of the penis is about 33% (1/3rd) of the length of the entire shaft (measured average, 32.1%; survey-weighted average, 37.5%). The ventral glans of the penis is about 12.5% (1/8th) of the length of the entire shaft (measured average, 12.6%; survey-weighted average, 11.7%). Measured proportions of the human penis follow exact fractions. Crowdsourcing data helped support photogrammetric analysis, with survey-preferred ratios within 5% of measured ratios. With further validation, these data can aid surgeons performing phalloplasty.

Taxonomic revision of the genus Trichopoda Berthold, 1827 (Diptera: Tachinidae: Phasiinae), with emphasis on the Neotropical fauna.

Trichopoda Berthold, 1827 is a tachinid genus belonging to the subfamily Phasiinae and natively distributed in the Americas. Species of Phasiinae are parasitoids of Hemiptera, especially Heteroptera, and are greatly important as biological control agents. Trichopoda is included in the "Trichopoda typica" group sensu Sabrosky, along with the genera Eutrichopoda Townsend, 1908 and Ectophasiopsis Townsend, 1915a. The genus Trichopoda includes several nominal species, many of which have been synonymized, whereas others have been transferred to different genera. Even though the group is morphologically remarkable for its bright colors and feather-like setae on the hind tibia and is important from an agricultural point of view, there have been no revisionary works dealing with its species. Before the present study, 22 valid species were included in Trichopoda, divided into two subgenera: Galactomyia Townsend, 1908 and Trichopoda s. str. In the current study, 25 species of Trichopoda are considered valid, of which twelve are described as new: Trichopoda (Galactomyia) auricauda sp. n., T. (G.) castannea sp. n., T. (G.) curvicercus sp. n., T. (G.) dupuisi sp. n., T. (G.) elongata sp. n., T. (G.) eupilipes sp. n., T. (G.) goiana sp. n., T. (G.) splendida sp. n., T. (G.) tenebrosa sp. n., T. (G.) tschorsnigi sp. n., T. (G.) urucurytuba sp. n. and T. (Trichopoda) sabroskyi sp. n. We also propose two new synonymies: Trichopoda (Galactomyia) giacomellii (Blanchard, 1966) syn. n. of T. (G.) pennipes (Fabricius, 1781) and T. (G.) nigripes Wulp, 1892 syn. n. of T. (G.) pennipes (Fabricius, 1781); the synonymies of T. ciliata (Fabricius, 1805) and T. haitensis Robineau-Desvoidy, 1830 with T. (G.) pennipes (Fabricius, 1781) are confirmed. We resurrect one species, T. (Galactomyia) limbata (Blanchard, 1966), which was previously synonymized under T. giacomellii (= T. pennipes). We also propose two new subgeneric combinations: T. alipes Wulp, 1892 and T. squamipes Wulp, 1892 are moved from the subgenus Galactomyia to the subgenus Trichopoda. The species aurantiaca Townsend, 1891 is considered as unrecognized within the genus Trichopoda, whereas T. mexicana Macquart, 1846 and T. subcilipes Macquart, 1844 are considered incertae sedis within the tribe Gymnosomatini. Three species are removed from the genus Trichopoda and placed in the genus Homogenia Wulp, 1892: Homogenia apicalis (Wiedemann, 1830), comb. n., H. decisa (Walker, 1853), comb. n. and H. luteipennis (Wiedemann, 1830), comb. n. We provide an identification key to Trichopoda species; due to lack of material, T. flava Röder, 1885 was not included in the key. The compositions of the two subgenera of Trichopoda are redefined for the Neotropical species, whereby all species previously placed in the subgenus Trichopoda by Guimarães, with the exception of T. alipes Wulp, 1892, T. indivisa Townsend, 1897 and T. squamipes, are transferred to the subgenus Galactomyia. On the other hand, the subgeneric placement of the Nearctic species stays the same. We also comment on and try to clarify possible misidentifications, notably for use of species in biological control programs. We present photographs of males and females of all examined species, as well as illustrations of almost all male and female terminalia.

Two new records of the subfamily Luciolinae Lacordaire, 1857 (Coleoptera: Lampyridae) with a checklist of genus Abscondita from India

Bioluminescence, being a fascinating adaptive manifestation of the animal kingdom, is displayed mostly by the insects belonging to the family Lampyridae, under the order Coleoptera. Two lampyrid species Abscondita terminalis (Olivier, 1883) and Triangulara frontoflava Pimpasalee, 2016 are recorded for the first time from India. Diagnosis, description of male genitalia, photographs of adult males, materials examined, distribution, remarks on habitat preference, and distribution pattern for both the species have been highlighted. A comprehensive checklist and key to Indian species of the genus Abscondita are also presented.

How Ethnicity, Expression, and Study Design Influence First Impressions of Approachability.

Over two studies, participants (total N = 642) rated a community sample of photographs of Black, East Asian, and White males who were smiling or portraying a neutral expression to see how participant ethnicity, target ethnicity, and target expression influence judgments of approachability (i.e., trustworthiness, friendliness, and threat). We also examined how a commonly used study design, in which each participant is asked to evaluate different groups of people, may motivate participants to adjust their ratings in an effort to avoid appearing biased. Results showed that the White participant group tended to rate smiling targets as friendlier (Studies 1 and 2) and more trustworthy (Study 1) than did the non-White participant group, which could be due to cultural differences based on majority versus minority status among the participants. In addition, the White participant group tended to rate White targets more positively than did the non-White participant group, suggesting an in-group bias. Finally, differences in results between Studies 1 and 2 suggest that study design can influence the degree of bias responding, highlighting the importance of incorporating a diversity of methods to better understand first impression judgments.
