Four new species of Nemobiinae from China (Orthoptera, Gryllidae, Nemobiinae)

摘要

Four new species of the cricket subfamily Nemobiinae from China are described. They are Homonemobius nigrus sp. nov., Speonemobius sinensis sp. nov., Polionemobius annulicornis sp. nov. and Pteronemobius yunnanicus sp. nov. All type specimens are deposited in East China Normal University, Biology of History Museum (HSNU); Shanghai Entomological Museum (IEAS) and Shanghai Normal University (SHNUC). The subfamily Nemobiinae includes 51 genera and about 291 known species. The largest genus, Pteronemobius, includes 100 species. This subfamily differs from the Trigonidiinae in the characters of hind tibiae being distinctly shorter than those of the hind femora and the second tarsal segment compressed. Thus far, four genera (Marinemobius, Dianemobius, Polionemobius and Pteronemobius) and 17 species have been reported from China. In this paper, four new species are described (Homonemobius nigrus sp. nov., Speonemobius sinensis sp. nov., Polionemobius annulicornis sp. nov., Pteronemobius yunnanicus sp. nov.) and the two genera Speonemobius and Homonemobius are first recorded from China.
