Bamboo plays an important role in the animal world, including providing a nutritious food source, shelter, and habitat. Inside of bamboo culm, we discovered a new genus of tarantula, which we describe here as Taksinusgen. nov. (♂♀). Specimens of this new tarantula were collected from Mae Tho, Mueang Tak district, Tak province, in Thailand, making it geographically distant from any other arboreal genera. Genital morphology was used to diagnose its genus, which is supported by distributional data, natural history, morphological characters, and photographic illustrations of the male and female. Diagnosis of the new genus was determined by distinguishing its different characters from those of other arboreal theraphosid spiders distributed throughout Southeast Asia. This tarantula’s specialization is that it lives in the stalks of the Asian bamboo Gigantochloa sp.

A new genus of the primitively segmented trapdoor spiders, which is endemic to the north of China, is described, Luthela gen. nov., and the status of Sinothela Haupt, 2003 and Sinothela sinensis (Bishop & Crosby, 1932) is discussed and both are treated as nomina dubia. The new genus Luthela gen. nov. is erected based on morphology and molecular data of the type species Luthela yiyuan sp. nov. A taxonomic revision of the new genus is given. Three Sinothela species are transferred to the new genus, L. luotianensis comb. nov. and L. schensiensis comb. nov. are redescribed using our newly collected specimens, include L. heyangensis comb. nov. as a junior synonym of L. schensiensis comb. nov., and describe six new species based on both male and female morphological characters: L. badong sp. nov., L. dengfeng sp. nov., L. handan sp. nov., L. taian sp. nov., L. yiyuan sp. nov., and L. yuncheng sp. nov.

AbstractVolumosinanew genus (Diptera: Sphaeroceridae: Limosininae) is described to accomodate the enigmatic Nearctic species Herniosina voluminosa Marshall, 1987 and its relationships are discussed. Based on morphological characters Volumosina is treated as part of the Limosina genus group along with Apteromyia Vimmer, 1929, Gigalimosina Roháček, 1983, Herniosina Roháček, 1983, and Limosina Macquart, 1835 but its position within the group remains unresolved. Volumosina voluminosa (Marshall, 1987) new combination is recorded from Canada and redescribed with new distributional and natural history data suggesting that it is an old-growth specialist associated with large woody debris. The gigantism of the male aedeagal complex of V. voluminosa is discussed.

AbstractFrom the endemic New World halyine genus Brochymena, two genera are recognized. New morphological characters at the generic level are described. Parabrochymena, new genus, with Pentatoma arborea Say as type species, is erected to contain 10 taxa formerly included in Brochymena. New combinations are Parabrochymena aculeata (Distant), P. apiculata (Van Duzee), P. arborea (Say), P. barberi barberi (Ruckes), P. barberi diluta (Blatchley), P. cuspidata (Distant), P. enigmatica (Ruckes), P. florida (Ruckes), P. haedula (Stål), and P. poeyi (Guérin-Méneville). Brochymena is redefined with 20 taxa: B. affinis Van Duzee, B. cariosa Stål, B. carolinensis (Westwood), B. chelonoides Ruckes, B. dilata Ruckes, B. exardentia Ruckes, B. hoppingi Van Duzee, B. humeralis Ruckes, B. laevigata Ruckes, B. lineata Ruckes, B. marginella Stål, B. myops Stål, B. parva Ruckes, B. punctata punctata Van Duzee, B. punctata pallida Blatchley, B. pilatei Van Duzee, B. quadripustulata (Fabricius), B. splendida Ruckes, B. sulcata Van Duzee, and B. tenebrosa Walker. Four synonymies are established: B. marginella Stål = B. carolinensis (Westwood); B. pilatei Van Duzee = B. sulcata Van Duzee; B. laevigata Ruckes = B. myops Stål; B. exardentia Ruckes = B. lineata Ruckes. Lectotypes are designated for B. affinis Van Duzee, B. cariosa Stål, B. myops Stål, B. punctata pallida Blatchley, and B. p. punctata Van Duzee. Species groups of Brochymena are characterized, and a key to all taxa is presented for the first time. As appropriate, for each species of Brochymena, the following are provided: citation of original description, synonymies, type material, diagnosis, description, geographical distribution, taxonomic comments, natural history, and illustrations of important structural characters. Chorological affinities are presented and systematic relationships are hypothesized.

A new riffle beetle, Zunielmis pax gen. et sp. nov., is described from Colombia (Vichada, Puerto Carreño, Bita River basin). It can be distinguished from all the other elmids by having large areas of a microgranular mesh (plastron) on the pronotum and elytra, crenulate lateral margin of the latter two, the shorter interocular distance than diameter of each eye, as well as by the characters of the structure of mandibles, the shape and sculpture of pronotum, and the structure of mesosternum, mesotibiae and elytra. The imagoes were collected on freshwater sponges. The habitat, where the new species was found, is described, and the adaptive meaning of the characteristics of plastron are discussed. Drawings and photographs of the adult habitus, distinctive morphological characters, and male and female genitalia are provided.

The New Zealand species of marsh beetles Atopida dorsale Broun, 1893 and Atopida testacea Broun, 1880 share several features that differentiate them from other members of Atopida White. Analysis of morphological characters and the structural anatomy of the genitalia justified the description of a new genus to accommodate these two species. Sensory structures of the apical maxillary palpomere are described for the first time in Scirtidae. The presence of lacinial hooks in Scirtidae is discussed. Morphology of female prehensors is described and observations of male and female genitalia during copulation are discussed. Lectotypes of both species are designated.

A new monotypic genus is herein described for the Western Cuban endemic whipscorpion Mastigoproctus pelegrini Armas, 2000. Its morphology is strikingly different from all other species of Mastigoproctus Pocock, 1894, but its generic placement remained unchallenged so far. Sheylayongium gen. n. is diagnosed from all other Mastigoproctinae Speijer, 1933 by a combination of several morphological characters of both sexes, e.g., high reduction of pedipalp armature and sexual dimorphism, carapace carination, unusual modification of sternite V, and female spermathecal structure. Its single species is thoroughly illustrated with high-resolution, full-color photographs, its geographical distribution is revised and updated, and new data are given on its natural history.
