(GH). Diagnosis. This species is readily distinguished from all other Pachyscia species by tuberculate mesonotum in male and posteriorly narrowing anal segment in female. Notes. Bi (1990) originally placed this species in Sinophasma Günther, 1940 . Chen and He (1996: 41) later transferred this species to Asceles Redtenbacher, 1908 based on Asceles quadriguttatus Chen & He, 1996 [= Pachyscia quadriguttata ]. Actually, the elongate and posteriorly notched anal segment in male and subapically lobed mesofemora in female shows the characters of the genus Pachyscia and therefore here transferred. First description and illustration of female was provided by Chen and He (1992: 44). Distribution. Hunan (Suoxiyu and Zhangjiajie), Guizhou (Fanjingshan) and Guangxi (Longsheng, Jinxiu and Xing’an), China .
