Species possessing 8–9 anal spines: Neonaphorura graffisp. nov. and Neonaphorura zakarpaticasp. nov. from different habitats in Ukraine: oak forest (Donets'k region, Dnipropetrovs'k region), and ‘stone steppe’ (Lugans'k region) (first species), and lowland meadow (Zakarpattya region) (second one) are described. These new species differ from the other representatives of this genus in the details of body chaetotaxy, number of vesicles in postantennal organ, number of sensilla on antennal segment IV, pseudocellar formulae and also location of anal spines. A table with comparison of diagnostic characters and geographical distribution of all known Neonaphorura species is given. An identification key to the Holarctic species is included.
The tribe Lyponiini is studied with morphology and seven new species from China are described: Lyponia (Lyponia) cangshanica sp. nov., L. (L.) hainanensissp. nov., L. (Poniella) pulchella sp. nov., L. (P.) qinlingensis sp. nov., L. (P.) tianquanensissp. nov., L. (Weiyangia) muyuensis sp. nov. and Ponyalis variabilis sp. nov. The diagnostic characters are described and illustrated.
Palaearctic species of the genus Scelolyperus Crotch, 1974 (Coleoptera: Chrysomelidae) are reviewed. Scelolyperus perreus sp. nov. from Turkey is described, illustrated and compared with Palaearctic species. Scelolyperus altaicus ssp. eous (Ogloblin, 1936) is elevated to species rank. Four taxa classified or associated with Scelolyperus are transferred elsewhere: Luperus pseudoaltaicusMedvedev, 1975 and Scelolyperus napoloviMedvedev, 2012 are transferred to EuluperusWeise, 1886; Adimonia glabraFischer von Waldheim, 1842 is not conspecific with Scelolyperus sericeus (Jacobson, 1894) but belongs to the genus AgelasticaChevrolat, 1836 and A. alni orientalisBaly, 1878 is proposed as its new synonym; forgotten Eugalera seminigraPic, 1903 is tentatively transferred to LuperusGeoffroy, 1762. The lectotypes are designated for Luperus altaicus ssp. eous and Adimonia glabra . Colour photo of habitus and both male and female genitalia are provided for all Palaearctic Scelolyperus species. Preliminary diagnostic table for Palaearctic “Luperus-like” genera is presented.
A new genus of Prionoceridae, Idgiaites gen. nov. (type species: I. jurassicussp. nov.), is described and illustrated from a well-preserved impression fossil from the Middle Jurassic Jiulongshan Formation collected at Daohugou Village, Shantou Township, Ningcheng County, Inner Mongolia, China. This is the first representative of Prionoceridae described from the Mesozoic era, and the presence of this family in the Jurassic indicates that cleroids were quite diverse during the early evolution of polyphagan beetles. The occurrence of plants in the same Formation may indicate that Idgiaites like it's modern confamilials were pollen-feeding.
The genus Bergenstammia Mik of Poland is reviewed. Differential diagnosis for species recorded from this country, including Bergenstammia glacialis sp. nov. described from the alpine zone in the Tatra Mts. are provided. The newly described species was found in the postglacial cirque in the glacier-fed stream. A key to the species of Bergenstammia nudipes group is also given as well as photographs of wings, illustrations of male and female terminalia and known distributions for species are included.
The monotypiC genus Gorochovitettix Storozhenko et Pushkar, gen. nov. (type species Gorochovitettix kannackiensis Storozhenko et Pushkar, sp. nov. from Vietnam) is described in the subfamily Metrodorinae. The new genus is similar to the genus OrthotettixHancock, 1909 from Malaysia, differing from the latter by the fore and mid femora considerably compressed laterally with the leaf-like upper and lower carinae. The new genus is similar to the genera VaotettixPodgornaja, 1986 from Vietnam and Paramphinotus Zheng in Zheng and Ou, 2004 from South China by the distinctly widened frontal ridge, differing from them by the antennal socket placed distinctly below the lower margin of eye.
A taxonomic review of Limoniinae (Diptera, Limoniidae) known from Eocene Baltic amber with particular references to the following genera is presented: Dicranoptycha Osten Sacken, 1860, Limonia Meigen, 1803, LipsothrixLoew, 1873, Rhipidia Meigen, 1818, Thaumastoptera Mik, 1866, ToxorhinaLoew, 1850, Trentepohlia Bigot, 1854. A new genus, Antoheliagen. nov., and two new species, Antohelia stanislawisp. nov., Trentepohlia (Trentepohlia) bajdaisp. nov. are described. The phylogenetic relationships of the Limoniinae known from Eocene Baltic are discussed based on the results of a newly performed cladistic analysis. The illustrated key for the genera of subfamily Limoniinae recorded from the Baltic amber inclusions is provided
Two new species from the genus Opadometa Archer, 1951 (Araneae: Tetragnathidae) are described, the O. sarawakensis sp. nov. and O. kuchingensissp. nov. from Bako National Park, Sarawak, Malaysia. Descriptions, illustrations and summary on the web characters are provided based on female specimens.
Euscorpiops artemisaesp. nov. from Myanmar and Euscorpiops orionisp. nov. from Thailand are described and compared with other species of the genus EuscorpiopsVachon, 1980. A key to the species of Euscorpiops is provided. Sexual dimorphism is present, as males of some species have a narrower pedipalp chela than females, while in other species the shape of the chela is the same in both sexes. Males of both new species have the pedipalp chela very narrow, in the male holotype of E. artemisaesp. nov. the chela length to width ratio is 4.13 and in the male holotype of E. orionisp. nov. it is 4.58. In addition to morphological analysis, we describe also the karyotype of male holotype and paratype of E. orionisp. nov. Both analyzed specimens have achiasmatic meiosis and the same number of chromosomes (2n=103) with predominance of acrocentric chromosomes gradually decreasing in size. During the first meiotic division we observed one trivalent in both males. This type of multivalent indicates centric fusion or fissions that may cause the differentiation of the karyotypes within the genus Euscorpiops.
