The Asian species of the genus Pachysternum Motschulsky, 1863 are revised and redescribed. Three new species are de-scribed: Pachysternum kubani sp. nov. (Laos, China: Sichuan), P. rugosum sp. nov. (China: Gansu, Shaanxi) and P. san-dacanum sp. nov. (Malaysia: Sabah, Sarawak). Three new synonyms are established: Megasternum gibbulumMotschulsky, 1866 and Pachysternum sibiricum Kuwert, 1890 are junior synonyms of Pachysternum haemorrhoumMotschulsky, 1866; Pachysternum nigritum Jia, Wu & Pu, 1998 is a junior synonym of P. stevensi Orchymont, 1926.Pachysternum keralense Hebauer, 2002 is transferred to the pilocnemoides group of the genus Australocyon Hansen,1990. Megasternum japonicum Shatrovskiy, 1989 is resurrected from the synonymy with M. gibbulum and considered asa valid name. Lectotypes are designated for the following species: Pachysternum apicatum Motschulsky, 1863, P. curva-tum Orchymont, 1925, P. haemorrhoum Motschulsky, 1866, P. nigrovittatum Motschulsky, 1863, P. sibiricum Kuwert,1890, Megasternum gibbulum Motschulsky, 1866 and M. distinctum Sharp, 1873. All Pachysternum species are diag-nosed, relevant morphological characters are illustrated, and an updated identification key is provided. Pachysternum api-catum is interpreted as a polymorphic species exhibiting high geography-based variation and possibly consisting of somesibling taxa; diagnosing of these taxa requires more material and additional (ideally molecular) characters and is therefore left unresolved at the present time.

Three new species of Otostigmus Porat, 1876 from Brazilian Atlantic Forest are described. Otostigmus beckeri sp. n. andO. lanceolatus sp. n. are described from the state of Bahia and O. giupponii sp. n. from the state of Espírito Santo. InBrazil, the otostigmine scolopendrid genus Otostigmus comprises 22 species. A summary of Brazilian Otostigmus speciesis presented with new distribution records, taxonomic remarks when appropriate and an identification key. Otostigmus sul-catus Meinert, 1886 is recorded for the first time from Brazil; the Andean Otostigmus silvestrii Kraepelin 1903, previouslyrecorded from Brazil, is here considered not to be present in this country. Eight nominal species are regarded here as newsynonyms. Five of them—Otostigmus pradoi Bücherl, 1939, O. longistigma Bücherl, 1939, O. longipes Bücherl, 1939,O. langei Bücherl, 1946 and O. dentifusus Bücherl, 1946—are based on females of O. tibialis Brölemann, 1902. O. latipesBücherl, 1954 is conspecific with and is considered a junior synonym of O. sulcatus Meinert, 1886; O. limbatus diminutusBücherl, 1946 is a junior synonym of O. limbatus Meinert, 1886 and O. fossulatus Attems, 1928 is a junior synonym of O. goeldii Brölemann, 1898. A lectotype is designated for O. goeldii.

Neomuscina Townsend includes 41 species distributed throughout the Nearctic and Neotropical Regions. Although the genus has a large number of species, it has been ignored and its taxonomy is confusing and has many flaws. In this work we analyzed the following species recorded for Brazil: Neomuscina atincta Snyder, N. atincticosta Snyder, N. capalta Snyder, N. currani Snyder, N. douradensis Lopes & Khouri, N. goianensis Lopes & Khouri, N. inflexa (Stein), N. instabilis Snyder, N. mediana Snyder, N. mimosa Lopes & Khouri, N. neosimilis Snyder, N. nigricosta Snyder, N. paramediana Lopes & Khouri, N. pictipennis pictipennis (Bigot), N. ponti Lopes & Khouri, N. sanespra Snyder, N. schadei Snyder, N. similata Snyder, N. stabilis (Stein), N. transporta Snyder, N. vitoriae Lopes & Khouri and N. zosteris (Shannon & Del Ponte). Neomuscina nigricosta and N. transporta are new distribution records for Brazil. Three new species are described: Neomuscina anajeensis sp. nov. from Anagé (Bahia), Neomuscina maculata sp. nov. from Botelhos (Minas Gerais) and Neomuscina snyderi sp. nov. from Mata de São João (Bahia). An identification key based on the morphological characters of both male and female is provided. Species distributions are discussed and updated, and the number of species now recorded for Brazil is 29.

The Indo-Australian crowned weevil genus Asytesta Pascoe, 1865 is revised. Forty-one species are recognized, including18 that are new: A. alexandriae, A. alexriedeli, A. allisoni, A. biakana, A. cheesmanae, A. concolora, A. emarginata, A.fayae, A. frontalis, A. gressitti, A. julieae, A. marginalis, A. morobeana, A. sedlaceki, A. thompsoni, A. tuberculata, A.vivienae, and A. woodlarkiana, new species. One subspecies, A. lugubris bidentata Voss is elevated to species status, A.bidentata Voss, new status. Four species are newly synonymized: A. circulifera Lea, 1928 = A. rata Heller, 1910, A.definita Faust, 1898 = A. humeralis Pascoe, 1865, A. granulifera Lea, 1928 = A. aucta Faust, 1898, and A. setipes Lea,1928 = A. lugubris Heller, 1895 new synonyms. Six new species groups are proposed. Lectotypes are designated for 18species. Two species are transferred from Asytesta to other genera: A. maura Pascoe to Microporopterus Lea and A.ypsilon Heller to Meroleptus Faust, new combinations. A checklist and key for all crowned weevil genera, key to speciesgroups and species of Asytesta, adult habitus illustrations, distribution maps, and line drawings of diagnostic charactersare provided.A phylogeny for the genus based on 82 adult morphological characters (187 states) for 41 ingroup taxa is alsopresented. All genera and species of the crowned weevil group as redefined here (including Cyamomistus Heller,Eudyasmus Pascoe, Glochinorhinus Waterhouse, Nothotragopus Zimmerman, Panopides Pascoe, and Zygara Pascoe),were included in the analysis to test the monophyly of Asytesta. Monophyly of Asytesta was supported only with thesynonymy of the monotypic genus Zygara. Accordingly, Zygara is a new junior synonym of Asytesta and Zygara doriae (Kirsch) is returned to its original combination with Asytesta; A. doriae Kirsch resurrected status.

Three New Species

The taxonomy of Dicerura Kieffer, 1898, a genus of Porricondylinae now comprising 32 species in the Holarctic region, is revised. Three new species are described based on morphological characters of male adults: D. jakovlevi Jaschhof & Spungis sp. nov. (from Finland), D. penttineni Jaschhof & Spungis sp. nov. (Finland), and D. yezoensis Jaschhof & Spungis sp. nov. (Japan). Dicerura padi Mamaev, 1975 syn. nov. is revealed to be a junior synonym of D. furculata Mamaev, 1968. Seven species, whose original descriptions are from a present-day perspective inadequate for the purpose of identification, are redescribed: D. barbata Mamaev, 1966; D. formosa Mamaev, 1998; D. foliicola Mamaev, 1968; D. furculata; D. iridis (Kaltenbach, 1873); D. stipator Mamaev, 1972; and D. unidentata Spungis, 1987. A key to males of Palearctic Dicerura is provided. New faunistic records are presented for D. barbata; D. complicata Spungis, 1987; D. dentata Spungis, 1979; D. formosa; D. fungicola (Mamaev, 1964); D. mixta Spungis, 1987; and D. unidentata. Male genitalic characters are shown to be useful to a certain extent for structuring the species diversity found within the genus Dicerura. The following groups of species are defined: iridis group (with nine species), dentata group (six species), fungicola group (four species), and formosa group (four species). Six of the species whose morphology is adequately known cannot be grouped within the proposed scheme, indicating the need for further character analysis and continuing search for yet undiscovered species that are assumed to exist in large numbers.

Three New Species

Stomopogon Malloch (Diptera, Muscidae) is a Neotropical genus recorded from Argentina, Bolivia, Brazil, Chile and Peru. In this contribution, the genus is revised, and three new species are described, one from Bolivia (Murillo, La Paz), one from Brazil (Palmas, Paraná) and one from Peru (Wayqecha, Cuzco). The descriptions include color images, illustrations and ultrastructural morphology of the terminalia of the adult. We provide an identification key to the species of Stomopogon and an updated map with species’ distributions. Stomopogon acuta (Malloch, 1934) is proposed as a new junior synonym of S. inculta Stein, 1911.

Three New Species

AbstractComposition, systematics, distribution and bionomics of the poorly known primarily Oriental genus Anchocerus Fauvel, 1905 is reviewed, with an annotated list and identification key provided for all 13 named species of the genus. The poorly known species from Papua New Guinea, A. punctus Last, 1980, A. similis Last, 1980 and A. wilhelmensis Last, 1980 are redescribed. Three new species, A. aparamerus sp.n. from Borneo, A. grandis sp.n. and A. thailandicus sp.n., both from Thailand are described. One species is transferred to Anchocerus from the genus Acylophorus Nordmann, 1837: Anchocerus tenuipes (Lea, 1929) comb. n., and also redescribed. Two species of Anchocerus are moved to Acylophorus: Acylophorus novaguinensis (Last, 1975) comb. n. and Acylophorus okasaensis (Last, 1975) comb. n. Morphological characters distinguishing the genera Anchocerus and Acylophorus are summarized. Type material was examined for all insufficiently known species.

Three New Species

Abstract Bees of the tribes Biastini, Neolarrini, and Townsendiellini are cleptoparasites in the subfamily Nomadinae (Hymenoptera, Apidae) and parasitize solitary bees. Understanding their phylogenetic relationships has proven difficult for many decades. Previous research yielded ambiguous results because of conflicting phylogenetic signals of larval and adult morphological characters. Molecular data settled some of this disparity but our knowledge remains fragmented due to limited taxon sampling and the discovery of a new lineage associated with Biastini: the enigmatic Schwarzia Eardley, 2009. Schwarzia has unusual morphological features and seems transitional between previously established taxa. This puts limits on our ability to diagnose the groups, understand their antiquity and biogeography, and study the evolution of host-choice. To address this, we integrate phylogenomics and morphology to establish a fossil-calibrated phylogeny for the tribes Biastini, Neolarrini, and Townsendiellini. We show that Schwarzia is indeed closely related to Biastes Panzer, 1806, but Biastes itself is paraphyletic in respect to Neopasites Ashmead, 1898, and even Biastini is paraphyletic due to Townsendiella Crawford, 1916, which is sister to Rhopalolemma Roig-Alsina, 1991. To ensure monophyly, we lower Neopasites to subgeneric rank within Biastes and resurrect Melittoxena Morawitz, 1873 as a third subgenus. We then assess the diagnosability of different tribal concepts and establish an expanded tribe Neolarrini that includes Biastini and Townsendiellini as new synonyms for Neolarrini. Neolarrini in this new, expanded sense likely originated in the Nearctic in the mid-Eocene and is, as far we know, composed exclusively of parasites of oligolectic hosts. Lastly, our continued efforts to find the rare Schwarzia in Eastern Africa led to the discovery of three new species, which are described herein.
