Hessebius luculentus, a new species of the genus Hessebius Verhoeff, 1941 from China (Lithobiomorpha, Lithobiidae)

Abstract

Hessebius luculentussp. n.(Lithobiomorpha: Lithobiidae), recently discovered from Shandan County, Zhangye City, Province Gansu, Qinghai-Tibet Plateau, China, is described. Morphologically it resemblesH. jangtseanus(Verhoeff, 1942), but can be easily distinguished from the latter by size of Tömösváry’s organ’s, the morphological characters of a protuberance on the dorsal end of the second article of the female gonopods; and obvious differences in the dorsal plectrotaxy of both the 14thand 15thlegs. The main morphological characters and a key to the known Chinese species of genusHessebiusbased on adult specimens are presented.
