Abstract

Hessebius luculentus sp. n. ( Lithobiomorpha : Lithobiidae ), recently discovered from Shandan County, Zhangye City, Province Gansu, Qinghai-Tibet Plateau, China, is described. Morphologically it resembles H. 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 14 ^th and 15 ^th legs. The main morphological characters and a key to the known Chinese species of genus Hessebius based on adult specimens are presented.
