Alpheus viserion sp. n. is described based on the material from Bocas del Toro archipelago on the Caribbean coast of Panama. The new species is morphologically closest to three members of the speciose A. armillatus H. Milne-Edwards, 1837 species complex, viz. A. carlae Anker, 2012, A. angulosus McClure, 2002, and A. tenuis Kim Abele, 1988, differing from them, as well as from all the other species currently included in this complex, by a suite of morphological characters and a diagnostic colour pattern. With the description of yet another new shrimp species from Bocas del Toro, the authors hope to contribute to the awareness that this archipelago represents one of the most biologically diverse places in the Caribbean Sea and to encourage the preservation of the remaining natural habitats of this unique area.Four new species are described Caribbomerus jaliscanus sp. nov. (Cerambycinae, Graciliini), from Mexico; Championa zarazagai sp. nov. and Championa chihuahuaensis sp. nov. (Cerambycinae, incertae sedis), both from Mexico; and Scopadus selkingi sp. nov. (Lamiinae, Acanthomerosternoplini), from Panama. We also propose keys for the following genera Neocompsa Martins, 1965; Placoclytus Chemsak Linsley, 1974; Nyssicus Pascoe, 1859; Championa Bates, 1880, and Scopadus Pascoe, 1857. Additionally, the differences between Hypexilis Horn, 1885 and Caribbomerus Vitali, 2003 are provided, Caribbomerus howdeni (Napp Martins, 1984) is synonymized with Hypexilis pallida Horn, 1885, and new records are registered.We provide diagnostics for eight species groups of Oriental Pseudopostega Kozlov (Lepidoptera Opostegidae) and a pictorial key for their identification. We designate three new species groups, P. frigida and P. strigulata groups, and the P. auritella group for two Palaearctic species, and rename the P. nigrimaculella group as the P. matrona group. We assign P. euryntis (Meyrick), P. zelopa (Meyrick), and P. Elimusertib manufacturer subviolaceae (Meyrick), three formerly unplaced species, to species groups based on re-examination of male and female genitalia. We list 22 currently known Oriental Pseudopostega species, and synonymize Pseudopostega spilodes (Meyrick), syn. nov., with P. machaerias (Meyrick). One new Mediterranean species with affiliations to the Oriental fauna, P. matrona Karsholt Remeikis, sp. nov., is described. The new species is illustrated with photographs of the adults and male genitalia. Additionally, we provide a distribution map of the P. matrona group, now extralimital to the Oriental region.The new genus Yanomamius n. gen. from Brazilian and Venezuelan Amazon is described, with three new species from Brazil Y. franciscoi n. sp. (type species), Y. raonii n. sp., and Y. neblina n. sp. The enigmatic Venezuelan species described as Holothele waikoshiemi Bertani Araújo, 2006 and presently included in Guyruita Guadanucci et al. (2007) is transferred to the new genus, making the new combination Y. waikoshiemi (Bertani Araújo, 2006) n. comb. Yanomamius n. gen. is closely related with the schismatotheline genera Schismatothele Karsch, 1879 and Euthycaelus Simon, 1889 sharing as probable synapomorphies a group of short spines on the retrolateral distal tibia of male palp and the shape of bulb. They differ by the position of the spines in a compact group instead of in rows and by a tapering embolus. Females differ from Schismatothele and Euthycaelus by the spermathecae weakly sclerotized. A series of recent phylogenies based on molecular data suggested a close relationship between schimatothelines and psalmopoeines. The male tibia I of Yanomamius n. gen. species have a series of ridges or a single protuberance behind the tibial apophyses that resemble those of psalmopoeines and strengthen the idea of close relationship of the two subfamilies.Boana hobbsi is a poorly known hylid frog currently placed within the Boana punctata group. Yet, morphological, ecological and bioacoustic traits do not support this placement, with no molecular data being available to date to test this hypothesis. Based on newly collected mitochondrial DNA sequences, morphological data review and field observations, we provide new insight into the phylogenetic relationships, morphological variations and geographic distribution of B. hobbsi. Our findings reveal that B. hobbsi is nested (with strong support) within the Boana benitezi group, recovering once more a polyphyletic Boana punctata group. Supported by this new genetic, morphological and ecological evidence, we propose a new taxonomic arrangement which includes B. hobbsi as a member of the Boana benitezi group. Furthermore, we emphasize the importance of conducting biological inventories in remote Amazonian areas, where many taxonomic and geographic knowledge gaps persist with regards to Amphibian diversity.A small Oriental genus Pompographa Gozmány, 1971 is reviewed, with three known species including a new species P. concaviella Park, sp. nov. described from Thailand. The recently described species from Laos, Torodora barathrona Park, 2020 is transferred to Prompographa, P. barathrona Park, comb. nov. Adult images of the three known species and genitalia of the two species, except the type species, are given.Lyriothemis pallidistigma sp. nov. (holotype male Cat Tien National Park, Dong Nai Prov., southern Vietnam) is described. This species is reminiscent of L. defonsekai van der Poorten, 2009 and L. elegantissima Selys, 1883, but can be separated by the shape of its secondary genitalia and its patterning. Information on its biology and ecology is provided.Five new species of the endemic Australian leafhopper genus Mayawa Fletcher, 2000 (M. affinifacialis sp. nov., M. bimaculata sp. nov., M. brevicephala sp. nov., M. kathyae sp. nov. and M. vestigia sp. nov.) are described and illustrated and a revised key to species is provided. One of the new species tested positive for a previously unknown strain of phytoplasma belonging to the 16SrV group. The related paralimnine genus Austroauridius gen. nov. based on A. iwaii sp. nov. from Queensland is also described and illustrated and a key to known genera of Australian Paralimnini is provided.Based on material collected by canopy fogging in forests on Borneo, Obhylius arboricola gen. nov., sp. nov., and Seticotasteromimus brunomanseri sp. nov., the second species of this genus, are described. Further records of the type species of Seticotasteromimus Germann, 2013, S. jarawa Germann, 2013, are presented from Borneo, some 2700 km distant from the type locality on the Andaman Islands. Along with Seticotasteromimus, the new genus is best placed in the subtribe Cotasteromimina.Two new species of Belisana Thorell, 1898 from Xishuangbanna, Yunnan Province, China, are described and illustrated Belisana bubeng sp. nov. (male, female) and Belisana xiaolongha sp. nov. (male).There are 29 species or subspecies in genus Hexacentrus occurring in Asia, Africa and Australia. Because of its similar appearance, it is not easy to distinguish them by traditional methods. In this study, we collected samples and sequenced COI genes from wide range. By reconstructing the gene tree, we found one new species, H. formosanus Chen et He sp. nov., from Taiwan. The new species is similar to H. expansus or H. inflatissimus, but differs from the former in male Cu2 vein of left tegmina curved and slender, and spectrum of male left tegmina slender and subsquare; differs from the later by body size smaller and female tegmina narrow and short. The type specimens are deposited in National Museum of Natural Science, Taichung, Taiwan (NMNS). H. japonicus hareyamai is treated as species level, H. hareyamai stat. nov.A new Tardigrada species, Claxtonia goni sp. nov. is described from specimens collected in the central area of the Haleakalā National Park, the island of Maui, Hawaii, U.S.A. The new species and Clx. pardalis (Degma Schill, 2015) together with several examples of Clx. wendti (Richters, 1903) are the only known Claxtonia species with the plates having an intracuticular pattern resembling that on a leopard's fur. Claxtonia goni sp. nov. differs from Clx. pardalis in the absence of pores on leg plates, in smaller and uniform pores on dorso-lateral plates, in very unequally spaced teeth in the dentate collar, in lesser ratio of internal cephalic cirrus and lateral cirrus A lengths, and in relatively shorter claws in fourth pair of legs. The differences between the new species and the other congeners as well as Echiniscus species with the same cirri composition and similar cuticular sculpture are also defined. The diagnosis of the genus Claxtonia is amended and three Echiniscus species are transferred into the genus with the proposed new combinations Claxtonia aliquantilla (Grigarick, Schuster Nelson, 1983) comb. nov., Clx. mosaica (Grigarick, Schuster Nelson, 1983) comb. nov. and Clx. nigripustula (Horning, Schuster Grigarick, 1978) comb. nov..The remarkable diversity in male and female genital morphology among the species of Sitona Germar might contribute to the understanding of the structural "lock-and-key" isolating mechanism. Recently, it has been found that in spite of the phallic sizes in male weevils of the genus Sitona, their internal sacs should precisely match with the vaginal infoldings of conspecific females. The present research also deals with the male transfer apparatus, which is a special organ for insemination procedure inside the female bursa copulatrix. A wedge-shaped structure with a fused ejaculatory pump was distinguished as the bio-syringe part of the transfer apparatus in the examined species. Two paired sclerites of the transfer apparatus support the bio-syringe, so that it would slide freely between them and lock precisely over the opening of the spermathecal duct inside the bursa copulatrix of the female. In this phenomenon, several new structures were also found, including a bursal sclerite ("bursal disc") and a pair of miniature pouches ("bursal plugs") which are embedded in the thickened wall of the female bursal lumen. These findings explain how the shapes of male and female copulatory organs are normally species-specific and provide an opportunity for understanding the role of the structural lock-and-key isolating mechanism.Four Chinese species of the genus Didrepanephorus Wood-Mason, 1878 with dense setae on dorsal surface are illustrated, including D. heterocolor Qiu, Zhao Xu, new species from Guizhou. Didrepanephorus mucronatus Arrow, 1921 and D. subvittatus Benderitter, 1922 are newly recorded from China in Yunnan and Guangxi respectively. Detailed descriptions, intraspecific variations, and natural history are provided for the aforementioned species. Previously unknown female of D. nishiyamai Muramoto, 2006 is documented for the first time.Andrena is the second most speciose genus of bees, with around 1,500 species known globally. It is predominantly distributed through the Holarctic with severely limited diversity in other biogeographical regions, and with the greatest species richness in arid and Mediterranean areas. Despite a long history of study, many species remain undescribed. As part of an ongoing revision of undetermined Old World material, many new species have been discovered in museum collections.
