First Canadian records of genera Apimela Mulsant & Rey and Gyronycha Casey from New Brunswick: description of two new species and new provincial distribution records (Coleoptera, Staphylinidae, Aleocharinae).

Two genera, Apimela Mulsant & Rey and Gyronycha Casey (both Aleocharinae: Oxypodini: Meoticina), are recorded from New Brunswick and Canada for the first time. The following species are newly recorded or described as new in New Brunswick and Canada: Apimela fusciceps (Casey); A. canadensis Klimaszewski & Webster, sp. n.; and Gyronycha pseudoobscura Klimaszewski & Webster, sp. n. The genera are defined and the key for species identification is provided. Color habitus images and black and white images of the median lobe of the aedeagus, spermatheca, tergite, and sternite VIII are provided for all species occurring in Canada, and Apimela macella (Erichson), the type species of genus Apimela, and G. valens Casey, the type species of Gyronycha.

Macrocyrtus imomzodai Barševskis, 2016, a new synonym of Metapocyrtus (Orthocyrtus) orbiferoides Schultze, 1918 (Coleoptera: Curculionidae: Entiminae).

Metapocyrtus (Orthocyrtus) orbiferoides Schultze, 1918 was described based on the female holotype collected from Ilocos Norte, North Luzon, Philippines. Since that time, it has been left unstudied for almost a century until I examined the holotype of M. (O.) orbiferoides in 2010 at Senckenberg Naturhistorische Sammlungen, Museum für Tierkunde, Dresden (SMTD). Recently, Barševskis (2016) described Macrocyrtus imomzodai based on two female specimens from Ilocos Norte, Luzon. Judging from the original description and dorsal and lateral habitus images, it is quite apparent that M. imomzodai is conspecific with M. (O.) orbiferoides. Here I propose a new synonymy based on these examinations. I thank Klaus-Dieter Klass, Olaf Jäger, Christian Schmidt, and Matthias Nuss (SMTD) for their support during my stay in Dresden. My thanks are also due to Steve R. Davis (American Natural History Museum, New York) and Naoko Nakahara (Tsukuba) for their help for preparing the manuscript.

Revision of the Neotropical water scavenger beetle genus Globulosis García, 2001 (Coleoptera: Hydrophilidae: Acidocerinae).

The Neotropical water scavenger beetle genus Globulosis García, 2001 is revised. Originally described from a single male specimen from southeastern Venezuela, the genus has since been found in localities across the Guiana Shield region and beyond, including Colombia, Suriname, Guyana, and Brazil. The genus is redescribed. Morphological characters and genetic data from the mitochondrial gene COI from ten populations across its range provide support for two distinct species, corresponding loosely to geography. The type species, G. hemisphericus García, is redescribed and newly recorded from Guyana, Suriname, and Brazil (Amazonas, Para). One new species is described, Globulosis flavus sp. n. from southwestern Venezuela (Amazonas, Bolivar). The genus is associated with lotic habitats, and typically found along the margins of small to medium sized streams. High-resolution habitus and aedeagal images and distribution maps for all species are provided.

A New Species of the Plant Bug Genus Rubrocuneocoris Schuh (Heteroptera: Miridae: Phylinae) from Hawaii

Abstract. A new species of the phyline plant bug genus Rubrocuneocoris Schuh (Hetereroptera: Miridae) is described from Hawaii. Although known only from the Oahu and Hawaii in the Hawaiian Islands, it is considered an adventive species originating from elsewhere in eastern Asia or the Indo-Pacific Region. A diagnosis, description, habitus images, and illustrations of male genitalia are provided to help distinguish this new species from the other 13 previously known species of the genus.

Identification and Oviposition Response of Sitophilus oryzae (L.) (Coleoptera: Curculionidae: Dryophthorinae) on Various Food Grains

In this study weevils were collected from the local areas of Tandojam and its surroundings. While further identification was performed at the Laboratory of postgraduate student, | department of Entomology, Faculty of Crop Protection, Sindh Agriculture University, Tandojam. The collected weevils from the local areas of Tandojam, were killed in a jar by applying potassium cyanide and were mounted through entomological pins on their right elytron. The specimens were also labeled, which contains information about the date of collection, name of collector, host of plant if was known. After that abdomen were separated and put at 10% potassium hydroxide for overnight at room temperature separately and were heavily sclerotized. The specimens were also heated for 10 minutes. In the next day these specimen were rushed in water for 5 minutes. During this experiment habitus images were taken with the help of camera fitted in microscope. The examination of gentile and other remaining parts were performed under the microscope for capturing of necessary images. For habitus images model of camera canon Power shot (sx510 HS) were utilized and for the gentile organ images USB camera fitted microscope 350k pixel (1) Kyowa Medilux (2) Labomed CSM2 20 to 40x were used. For the oviposition response on various grains, tested grains include; wheat, barley, oat, maize, gram, millet. A pair of newly emerged Sitophilus oryzae (Fabricius, 1775) from a laboratory colony was placed in plastic jars of 150 ml. There were 6 treatments, each treatment with 3 replications. Eggs were counted in each jar containing pair of weevils. Analysis was carried out through statistical software SXW 8.0, to categorize the preference of Sitophilus oryzae.

Carvalhoma malcolmae Slater & Gross, 1977 and C. taplini Slater & Gross, 1977 are redescribed. Three species, C. ovatum sp. nov., C. parvum sp. nov., and C. weiri sp. nov., are described as new to science. A key to species, digital habitus images, SEM images, drawings of male and female genitalia and distribution map are provided.

Two new genera of big-eyed minute litter bugs (Hemiptera, Schizopteridae, Hypselosomatinae) from Brazil and the Caribbean

Charismatic Hypselosomatinae (currently 14 extant and fossil genera; 72 species), the “big-eyed minute litter bugs”, are characterized among Schizopteridae (Dipsocoromorpha) by the large eyes, four-segmented labium, and distinctive wing venation. A recent molecular phylogenetic analysis confirmed the monophyly of Hypselosomatinae that were recovered as the sister taxon to the Ogeriinae + Schizopterinae (Weirauch and Štys 2014). Hypselosomatinae occur in the Old and New Worlds, but described species diversity is biased towards the Oriental and Australian regions: only three monotypic genera are currently known from the New World (Glyptocombus Heidemann, Ommatides Uhler, and Williamsocoris Carpintero & Dellapé). Based on 28 male, female, and juvenile specimens from Cuba and the Dominican Republic and a single male specimen from Brazil we here describe two new monotypic genera of Hypselosomatinae, Hypselosomops pecki gen. n. and sp. n., and Hypsohapsis takiyae gen. n. and sp. n. We provide habitus images, digital illustrations (light, scanning electron, and/or confocal microscope) of wing and male genitalic structures, line drawings of genitalic structures, and distribution maps. Bizarre morphologies, a worldwide distribution with small endemic species ranges, and a fossil record that dates back to the mid-Cretaceous make the Hypselosomatinae a fascinating group to explore in an effort to understand the evolutionary history of Dipsocoromorpha.

Scratching the surface? Taxonomic revision of the subgenus Schizoptera (Odontorhagus) reveals vast undocumented biodiversity in the largest litter bug genus Schizoptera Fieber (Hemiptera: Dipsocoromorpha).

Schizoptera Fieber, currently the largest genus of litter bugs (Hemiptera: Dipsocoromorpha), comprises 61 extant species in 4 subgenera. Specimens are abundant in New World bulk and residue samples. Schizoptera species showcase stunning morphology including intricate, asymmetrical genitalia in males that have proven to provide excellent species diagnostic features in the past. Recent bulk sample sorting efforts have revealed a vast number of Schizoptera specimens from across the New World, with the majority representing undescribed species. We here taxonomically revise the subgenus Schizoptera (Odontorhagus) that has recently been shown to form a monophyletic group within Schizoptera. Characterized by the blunt tooth on the posterior margin of the propleuron, Schizoptera (Odontorhagus) previously comprised 10 species from Central and the northern part of South America. We here describe 20 new species in S. (Odontorhagus): S. acuta, n. sp., S. angularis, n. sp., S. ansata, n. sp., S. aspera, n. sp., S. brevis, n. sp., S. dentata, n. sp., S. dolosa, n. sp., S. enigmatica, n. sp., S. exacta, n. sp., S. gorgonensis, n. sp., S. insidiosa, n. sp., S. monstrosa, n. sp., S. piscicaudata, n. sp., S. quasicompleta, n. sp., S. radicata, n. sp., S. serrata, n. sp., S. simpla, n. sp., S. singularis, n. sp., S. trivialis, n. sp., S. ungulata, n. sp., increasing the species count of Schizoptera to 81. We provide morphological documentation including digital habitus images and genitalic drawings for all new species and document and redescribe existing species where feasible. Distribution maps and a key to the species of Schizoptera (Odontorhagus) are also presented. We predict that similar increases in species numbers are to be expected for the remaining subgenera of Schizoptera, making this genus a very diverse lineage of minute litter bugs.

Pigritia crocea (Braun, 1918), New Combination (Lepidoptera: Gelechioidea: Blastobasidae), Transferred from Exegetia Braun, 1918, New Synonymy (Yponomeutoidea: Lyonetiidae)

Abstract. Exegetia crocea Braun, 1918, (Yponomeutoidea: Lyonetiidae), type species of Exegetia Braun, 1918, n. syn., is transferred to Pigritia Clemens, 1860 (Gelechioidea: Blastobasidae). Pigritia crocea (Braun, 1918), n. comb., is redescribed, and morphological evidence is provided in support of its new generic and familial assignment. A habitus image of the male holotype and illustrations of the male genitalia and wing venation of a conspecific male are included.

New genus and species of Aleyrodidae (Hemiptera: Sternorrhyncha) from North‐Eastern India, with remarks on its relationships with allied genera

AbstractA new genus and species of whitefly, Arunaleyrodes geminus, are described from Sago forests of Arunachal Pradesh in North‐Eastern India. Habitus images, camera lucida drawings and scanning electron micrographs are provided to supplement the description and discussions. This new genus is distinguished from Aleurotuba in having long anterior and posterior marginal setae, apically rounded ensiform dorsal setae (except caudal setae), each marginal tooth with a wax‐secreting longitudinal groove along the axis of the tooth, and posteriorly elevated vasiform orifice. An apparently closely related genus, Aleurotuba, is diagnosed, discussed and illustrated here.

Small Bugs, Big Changes: Taxonomic Revision of Orthorhagus McAtee & Malloch.

The Schizopteridae, the largest family of litter bugs (Hemiptera: Schizopteridae), comprises 53 genera of primarily tropical, tiny true bugs. The largest genus Schizoptera Fieber comprises 64 described species and six subgenera with primarily tropical and subtropical distributions across the New World. Schizoptera species are morphologically diverse with extreme asymmetry of male genitalia and sexually dimorphic wing in females of some species. Subgeneric concepts of Schizoptera are yet to be evaluated in a phylogenetic context. The subgenus Orthorhagus McAtee & Malloch was described from a single specimen as part of Schizoptera based on similarities of wing venation and other structures. The absence of a pronotal collar was used to separate Orthorhagus from other subgenera within Schizoptera, but morphological and molecular data show that the differences between Orthorhagus species and those of Schizoptera extend beyond the lack of a pronotal collar. In this study, we elevate the subgenus Orthorhagus to generic rank and describe five new species in this genus. We provide morphological documentation including digital habitus images, genitalic drawings, and confocal micrographs for all species. Distribution maps and a key to the species of Orthorhagus, n. stat. are also presented.

Review of the seven new species of Isometopinae (Heteroptera: Miridae) in Australia and discussion of distribution and host plant associations of the subfamily on a worldwide basis

AbstractThe Isometopinae are a poorly known subfamily of Miridae (Heteroptera) with 42 genera and 239 described species worldwide. Prior to this study, the subfamily was represented in Australia by a single species, Eurocrypha thanatochlamus. In this work, three isometopine genera, Jozefus, Paratopus and Myiomma, are reported from Australia for the first time, and Australotopus gen. nov. is described as new to science. The following seven new species are described: Australotopus cooperensis sp. nov., Jozefus brunetus sp. nov., Jozefus monteithi sp. nov., Myiomma albalata sp. nov., Myiomma basseti sp. nov., Paratopus brunocapitus sp. nov. and Paratopus flavocapitus sp. nov. Habitus images, scanning electron micrographs, measurements and illustration of male and female genitalia are provided to support the diagnoses of the above taxa. The distribution and plant associations of the subfamily Isometopinae are discussed.

Two New Species ofPulvillophylusfrom Western Australia (Insecta: Hemiptera: Miridae: Phylinae: Cremnorrhinini)

ABSTRACT Two new species of phyline Miridae were collected from unique localities in Kadji Kadji and Lochada Reserves of Western Australia during the Avon Wheatbelt Bush Blitz survey of September 2009. Based on head shape and male genitalic structure, P. cuneomaculatus, n. sp., and P. ecdeiocoleae, n. sp., are members of Pulvillophylus Schuh and Schwartz, 2016. The latter species was taken on the flower spikes of Ecdeiocolea monostachya F. Muell. (Ecdeiocoleaceae) and provides the first confirmed host-plant record for the genus Pulvillophylus. Documentation for both species is provided by diagnoses, descriptions, color habitus images of males, a distributional map, illustrations of male genitalic structures, and images of the endosoma. Digital images of the dorsal habitus and female genitalic structures of P. ecdeiocoleae are provided as well as digital images and a distribution map for the plant host.

Two new species and new provincial records of aleocharine rove beetles from Newfoundland and Labrador, Canada (Coleoptera, Staphylinidae, Aleocharinae).

Two new species, Atheta pseudovestita Klimaszewski & Langor, sp. n., Silusa prettyae Klimaszewski & Langor, sp. n., are described, and 16 new provincial records, including one new country record, of aleocharine beetles are presented for the province of Newfoundland and Labrador. Diagnostics, images of habitus and genital structures, distribution, bionomics information and new locality data are provided for the newly recorded species. A new checklist with 189 species of aleocharines recorded from the province is presented.

A revision of Chilicola (Heteroediscelis), a subgenus of xeromelissine bees (Hymenoptera, Colletidae) endemic to Chile: taxonomy, phylogeny, and biogeography, with descriptions of eight new species.

The bee subgenus Chilicola (Heteroediscelis) Toro & Moldenke, 1979 (Hymenoptera, Colletidae, Xeromelissinae) is revised. The subgenus is considered endemic to Chile and occurs across a broad range of habitats. Eight new species are described: Chilicola (Heteroediscelis) charizard Monckton, sp. n., Chilicola (Heteroediscelis) curvapeligrosa Monckton, sp. n., Chilicola (Heteroediscelis) guanicoe Monckton, sp. n., Chilicola (Heteroediscelis) katherinae Monckton, sp. n., Chilicola (Heteroediscelis) lickana Monckton, sp. n., Chilicola (Heteroediscelis) mayu Monckton, sp. n., Chilicola (Heteroediscelis) packeri Monckton, sp. n., and Chilicola (Heteroediscelis) randolphi Monckton, sp. n. One of the existing species, Chilicola (Heteroediscelis) valparaiso Toro & Moldenke, 1979, syn. n., is treated as a junior synonym of Chilicola (Heteroediscelis) mantagua Toro & Moldenke, 1979, and the nine remaining valid species are redescribed. Thoroughly illustrated keys to species for males and females are provided, along with habitus images, images of male terminalia, distribution maps for each species, and a map of relevant Chilean biogeographic regions. Results of phylogenetic analyses are presented, based upon 74 morphological characters and on CO1 barcode sequences, analyzed both separately and as a combined dataset. Monophyly of the subgenus is supported, and groupings within the subgenus are discussed in light of a biogeographic analysis of their species distributions (spatial analysis of vicariance), whereby divergence between taxa is found to occur primarily via north-south disjunctions.
