Diagnosis. Pincerna costulosus is characterised by a small sized, translucent, high conical shell with strongly, regularly ribs on R1, and R2 extremely short.

Distribution. Pincerna costulosus is known from northwestern Vietnam (Lai Châu Province) and Southwest China (Yunnan Province) ( Chen & Wu, 2020).

Remarks. The species is quite stable in terms of shell characters, although only a few shells are known. Pincerna costulosus has been recently recorded from Xishuangbanna, Yunnan Province, China ( Chen & Wu, 2020). The present record extends the distributed range circa 400 km to the west.
