MORFOLOGÍA DE LOS GENITALES MASCULINOS DE TRES ESPECIES DE MUSCIDAE (INSECTA: DIPTERA) DE IMPORTANCIA FORENSE EN COLOMBIA

Forensic entomology employs the biology and ecology of insects in medico-legal cases. For a precise application in this context, it is necessary to make a correct taxonomic identification in any developmental stage of the specimens related to a case. Incomplete or damaged samples of adults are often obtained from the case scene, making taxonomical identification unlikely. Muscidae is one of the families commonly found in the forensic context. The objective of this study is to describe and to illustrate the morphological characteristics of the adult male genitalia of Biopyrellia bipuncta (Wiedemann, 1830), Musca domestica Linnaeus, 1758 and Synthesiomyia nudiseta (Wulp, 1883), species with forensic importance in Colombia. Male genitalia structures like V sternite, the cercal plate, the surstyli and aedeagus are described and illustrated. Additionally complementary Diagnosis of external morphological characteristics are provided.

A new species of the genus Dolichopoda (Orthoptera: Rhaphidophoridae) from Teke Peninsula, Turkey

Dolichopoda fortuita sp. nov. from Teke Peninsula in Southern Turkey is a second Turkish species of this genus with the epiphallic process of male genitalia bifurcate. Description of this species is provided with a brief morphological analysis of the general plan of male genitalia structure.

Redescription of Ecdyonurus (Ecdyonurus) russevi Braasch & Soldán, 1985 (Ephemeroptera: Heptageniidae).

This study is focussed on the redescription of Ecdyonurus (Ecdyonurus) russevi Braasch & Soldán on the basis of the type material (holotype and paratypes) and topotypes collected in the Strandzha Mts. (Bulgaria). Female imago and subimago, larva and egg of the species are described for the first time and the male imago is redescribed in detail. The features distinguishing the species from other representatives of the genus Ecdyonurus are presented. Ecdyonurus russevi differs by the combination of several characters in the colour pattern of abdominal terga and wings, colour of lateral portion of male eyes and male genitalia structure in adults; some overlap has been observed in the number of groups of setae, bristles and hair-like setae on maxillae and labial palps, shape of pronotal projection and colour of tarsi in larvae; and insignificant number of knob-terminated coiled threads on exochorion, with only a few such attachment elements on one pole in eggs. Biology and present distribution of the species are discussed.

A contribution to knowledge of Dermestidae (Coleoptera) from Kazakhstan with description of one new species.

Research on skin beetles of tugai forests with use of passive window traps was performed in Almaty region in Kazakhstan in 2013. Ctesias (Decemctesias) yuliyae sp. nov. is described, illustrated, and compared with similar species of the genus Ctesias subgenus Decemctesias Háva, 2004. The new species differs by the structure of antennae and male genitalia. Eighteen other dermestid species from Kazakhstan were also recorded in this study.

Studies on genitalia of four type species of subfamily ennominae (Lepidoptera: Geometridae)

Critical observations have been made on the structure of male and female genitalia of four type species, namely Anonychia grisea (Butler), Ctenognophos eolaria eolaria (Guenee), Heterostegane subtessellata (Walker) and Hydatocapnia marginata (Warren) belonging to the subfamily Ennominae under Geometridae of Lepidoptera. In addition, generic characters of the dealt with genera have also been documented.

Notes on Ultrapsammophilous Erodiini from Iran (Coleoptera: Tenebrionidae: Pimeliinae)

Abstract. The redescriptions of Hyalarthrodosis monodi (Pierre, 1974) and Hyalerodius jirofti Kaszab, 1979, species hitherto known from single and damaged specimens, are supplemented based on the newly accessed material. The structure of male genitalia of these taxa is described for the first time. The key to the Asian genera of the Arthrodosis-like Erodiini is modified to include new diagnostic characters. New distributional records for the studied species are provided. The evolutionary adaptations to the ultrapsammophilous lifestyle within Tenebrionidae are discussed.

PHOLEUONOPSIS (PHOLEUONOPSIS) PERUCENSIS SP. N., A NEW TROGLOBITIC LEIODID BEETLE (COLEOPTERA: LEIODIDAE: CHOLEVINAE: LEPTODIRINI) FROM BOSNIA AND HERZEGOVINA

A new leptodirine beetle species, Pholeuonopsis (Pholeuonopsis) perucensis sp. n., from a cave in Eastern Bosnia and Herzegovina is both described and diagnosed. The structure of both male and female genitalia and other taxonomically important characters are imaged. The new beetle species is clearly distinct from all other congeners. It probably belongs to an old phyletic lineage of Tertiary origin, like other known Pholeuonopsis taxa from the Western Balkan Peninsula. The new species is both an endemic and a relict inhabiting solely Eastern Bosnia and Herzegovina.

A new genus of trechine beetles, Puertrechus gen. n., with two new species and a new species of Dactylotrechus Belousov et Kabak, 2003 from Southern China (Coleoptera: Carabidae: Trechinae).

Puertrechus gen. n., related to both Dactylotrechus and Quiennectrechus Deuve, 1992 is established to accommodate two new trechine species: P. mengsaensis sp. n. (type species of the genus, type locality: Mountains East of Mengsa City, Lincang Prefecture, Yunnan, China) and P. daxueshanicus sp. n. (type locality: Daxueshan Mount, the same prefecture). Likewise, the second species of the genus Dactylotrechus Belousov & Kabak, 2003, D. yalongensis sp. n., is described from the right bank of the Yalong River, SW of Mianing, southern Sichuan, China. This species differs from the only known species of the genus in some important characters including the elytral chaetotaxy and the male genitalia structure. Some adjustments of the genus diagnosis are made to embrace the new species. Keys to species of Dactylotrechus and Puertrechus gen. n. are included and their distribution is mapped. A key is provided to differentiate Puertrechus , Dactylotrechus and Quiennectrechus.

Wing pattern morphology of three closely related Melitaea (Lepidoptera, Nymphalidae) species reveals highly inaccurate external morphology-based species identification

Wing morphology of the three closely related species of Melitaea - M. athalia (Rottemburg, 1775), M. aurelia (Nickerl, 1850) and M. britomartis Assmann, 1847 - co-occurring in the Balkans (SE Europe) was investigated in detail through visual inspection, morphometric analysis and multivariate statistical analysis. Results are compared to recent phylogenetic studies, searching for concordant patterns and discrepancies between the two approaches. The morphology of the genitalic structures is also com- pared with the results of the other two approaches. The main conclusions are as follows: (1) small albeit significant differences in wing morphology exist among the three species and (2) while the structure of male genitalia and phylogenetic position of the three species are concordant, they are (3) in discordance with the wing morphology. The present study represents another example where identification based on external morphology would lead to highly unreliable determinations, hence identification based on phy- logenetic studies and/or genitalia is strongly recommended not only for the three studied species but also more broadly within the genus. Furthermore, we show that some of the characters generally used in the identification of these three Melitaea species should be avoided in future.

The genus Typhlocharis Dieck 1869 (Coleoptera: Carabidae): description of a new species from Portugal and remarks on the external microsculpture of the last abdominal sternum “belt”

SummaryThe endogean carabid Typhlocharis zaballosi n. sp., belonging to the T. gomezi group, is described and illustrated. The work provides diagnostic characters, in particular the structure of male and female genitalia, affinities to putative relatives and some remarks on its ecology and distribution. A key for the identification of all known species of the T. gomezi species group are provided. Some remarks on the external microsculpture of the last abdominal sternum “belt” of T. carinata Serrano & Aguiar 2006, T. quarta Pérez-González & Zaballos 2013, T. crespoi Serrano & Aguiar 2007 and T. zaballosi n. sp. are given. An overall revision of the presence/absence of this structure in the genus is provided and its taxonomic relevance is also discussed.

Magyarország Cnephasia fajai (1.) (Lepidoptera: Tortricidae)

The present study aims to gather all the information available on the diagnosis of Cnephasia asseclana, C. chrysantheana species in Hungary, as a starting point for a subsequent paper on the dynamics of distribution limits. The information was mainly derived from lepidopterological collections and faunistic studies. Working with population samples of several taxa one obtains greater variety of information, both qualititative and quantitative. These observations raised at least two problems: (1) it was not possible to report data from localities where two or more species occur sympatrically, and when they could not be positively distinguished by means of morphological characters; (2) in 2010–2014 the author collected museum material from different localities of Hungary; detailed structure of male and female genitalia of several specimens from within the accepted range of nominal Cnephasia was studied, but this provided no quantitative data. Distribution maps of the species show the probable resident distribution area (grey), together with localities from which specimens have actually been examined (black dots). In text of the Hungarian distribution and phenology, detailed information is also included about flight period, biology including foodplants and habitat including the altitude range. Structure of genitalia and morphological characteristics of wings are illustrated with figures. Colour photographs and drawings of adults and genitalia of both sexes are provided for identification of each described species. Ample illustrations of differential features will facilitate identification. At present, 12 Cnephasia species are known from Hungary, and are included in the Checklist, together with the most important synonyms. The study series is intended for both amateurs and professionals as well as for those engaged in applied lepidopterology. With 24 figures.

New species of the genus Colobostema Enderlein (Diptera: Scatopsidae) from Mexico.

Five new species of the genus Colobostema Enderlein, 1926 from Mexico are described and illustrated: C. emilianoi (Chiapas), C. marielae (San Luis Potosi), C. valentinae (Jalisco), C. lupitae (Oaxaca) and C. marlettae (Yucatan). A key to the males of Neotropical species of Colobostema is provided. The male genitalia structures (especially the vestiture of parameres and the shape of tergite 9) indicates that all these new species form a group of closely related taxa, associated to the species of the Nearctic and Neotropical region.

Studies of true bugs of Xinjiang, western China. I. Leptopodomorpha: shore bugs (Hemiptera: Heteroptera: Saldidae)

The family Saldidae in Xinjiang (Western China) includes 19 species belonging to five genera from the subfamilies Chiloxan-thinae (1 sp.) and Saldinae (18 spp.). A new species, Halosalda minuta Vinokurov, Luo & Lü, sp. n., is described from the east-ern part of the Tarim depression. The new species differs from congeners by the small body size, relatively large head, longerantennal segment 2, and structures of male genitalia. S. sibiricola Cobben, 1985 is recorded as new for China, and three speciesare new to the fauna of Xinjiang: Saldula orthochila (Fieber, 1859), S. pallipes (Fabricius, 1794), and Salda littoralis (Linnaeus, 1758). Halosalda lateralis (Fallén, 1807) is reported for Kyrgyzstan for the first time.

To the knowledge of the herbivorous scolytid genus Thamnurgus Eichhoff (Coleoptera, Scolytidae)

Based on the male genitalia structure, 3 subgenera are distinguished in the genus Thamnurgus: Thamnurgus s. str. (type species Thamnurgus euphorbiae Kuster; the subgenus includes also Th. characiae and Th. varipes), Parathamnurgus subgen. n. (type species Thamnurgus caucasicus Reitter; includes also Th. armeniacus, Th. kaltenbachii, Th. brylinskyi, and Th. pegani) and Macrothamnurgus subgen. n. (type species Thamnurgus delphinii Rosenhauer; includes also Th. petzi and Th. rossicus). Thamnurgus s. str. comprises species with the aedeagus lacking supporting apical structures and with unbranched apophyses. In the two other subgenera the aedeagal apophyses are branched and the apical supporting structures are differently arranged. Species of Thamnurgus s. str. are associated exclusively with Euphorbiaceae, species of Macrothamnurgus, with Ranunculaceae, and those of Parathamnurgus, with plants of several families. A key to Palaearctic Thamnurgus species based on the external and genital characters is proposed. The host plants and distribution of some species are clarified. In the aedeagus structure, the Palaearctic Thamnurgus species clearly differ from the African Thamnurgus and also from the members of Taphronurgus, Cynanchophagus, Triotemnus, and Xylocleptes. Data on the male genital structure support generic distinctness of Thamnurgus, Taphronurgus and Xylocleptes. Lectotypes of Th. armeniacus Reitter, 1897, Th. brylinskyi Reitter, 1889, Th. characiae Rosenhauer, 1878, Th. declivis Reitter, 1897, Th. delphinii (Rosenhauer, 1856), Th. pegani Eggers, 1933, and Th. petzi Reitter, 1901 are designated. Thamnurgus jemeniae Schedl, 1975 is transferred to Xylocleptes, and Th. orientalis Schedl, 1978, to Pseudothamnurgus. Based on the endophallus characters, Thamnurgus ugandensis Nunberg, 1961 and Th. lobeliae Eggers, 1939 are considered to belong to a genus distinct from the Palaearctic Thamnurgus.

Revisión del género Cantabrogeus Salgado, 2000, con la descripción de tres nuevas especies hipogeas endémicas de la Cordillera Cantábrica (Coleoptera, Leiodidae, Cholevinae, Leptodirini)

A revision of the genus Cantabrogeus Salgado, 2000, with description of three new hypogean species endemic to the Cantabrian mountains (Coleoptera, Leiodidae, Cholevinae, Leptodirini) The two previously known species of the genus Cantabrogeus (Coleoptera, Leiodidae, Cholevinae, Leptodirini) are redescribed, and three new species are described: Cantabrogeus antimachus n. sp., C. cultellus n. sp. and C. fresnedai n. sp. One of these (C. antimachus n. sp.) is tripliod (3n = 33) and the first known parthenogenetic species of Leiodidae. The relationships between the different taxa are discussed based on external morphological characters and the structure of male and female genitalia, as well as the distribution of the species in the different areas in the Cantabrian mountains (NW Iberia). Analyses of molecular data (fragments of seven mitochondrial and nuclear genes) confirms the monophyly of Cantabrogeus and its sister–group relationship with Fresnedaella, as well as its inclusion within the paraphyletic series Quaestus. The parthenogenetic species (C. antimachus n. sp.) has a derived position within Cantabrogeus, which, according to previous estimates of the molecular rate, probably diversified during the Pliocene–Pleistocene in the Cantabrian karst areas, of a high tectonic complexity.

Australodindymus nigroruber gen. et sp. nov. from Western Australia (Hemiptera: Heteroptera: Pyrrhocoridae)

A new genus and species, Australodindymus nigroruber gen. et sp. nov., is described from the Pilbara region of WesternAustralia based on male, female and 5th instar nymph. This endemic genus is related to the cosmopolitan genus, DindymusStål, 1861, but differs markedly in structure of both male and female genitalia, and is the first member of the Pyrrhocoridae recorded from Western Australia.

Гомологии в структуре гениталий самцов круглошовных мух (Cyclorrhapha: Diptera)

Two new species of the genus Geocharis Ehlers, 1883 and new data on Anillina species from Portugal (Coleoptera: Carabidae)

Two new species of the genus Geocharis Ehlers, 1883 (Carabidae: Trechinae, Anillini) are described (Geocharis barcorabelo n. sp. and Geocharis antheroi n. sp.) from the northern region of Portugal (Iberian Peninsula). This work provides diagnostic characters for these species and, in particular, for the structure of male genitalia. The affinities with other known species namely their putative closest relatives, as well as ecological and biogeographical comments are also included. A key for the identification of the males of the Geocharis species found north of the Tejo River in Portugal is also provided. New chorologist data on other endogean carabids from Portugal are also included.

A new species of the genus Macrosaldula Leston et Southwood, 1964 (Hemiptera: Heteroptera: Saldidae) from Northwestern China

Macrosaldula bogdashana Luo et Vinokurov sp. n. is described from Bogda Shan Range, Northwestern China. The new species is most similar in size and vestiture to M. oblonga oblonga (Stål, 1858) but differs in the color pattern of forewings (Fig. 1-3) and male genitalia structure (Figs. 11–14). M. bogdashana is also similar to M. tadzhika (Kiritshenko, 1912) in the same vestiture, but can be distinguished from the latter by the shorter body (see Table), shape of pale spots on corium (Figs. 6–9), and the male genitalia structure (Figs. 15–18).
