DIAGNOSIS. — A Coccoglypta species with a keeled body whorl, light brown, greenish to greyish colour and strong sculpture on the ventral shell surface.

DISTRIBUTION. — This species is more widely distributed than C. liui Páll-Gergely , n. sp. Namely, it was collected on the Emei Shan, the Qingcheng Shan and Fengqishan.

COMPLEMENT OF DESCRIPTION

Shell dextral, rather large, light brown, greenish to greyish, dorsal and ventral surface of similar colour; shell depressed globular or conical, body whorl slightly or prominently keeled; entire shell consists of 5.25-5.75 whorls, separated by rather shallow suture; protoconch consisting of 1.5-1.75 whorls, matt, rather smooth, dorsal side of teleoconch dominated by irregular, very rough wrinkles and strong tubercles (tubercles appearing after the first 1.5 whorls of teleoconch); some fine spiral grooves also visible, especially close to the suture; ventral surface similar to dorsal, although with slightly weaker sculpture; aperture strongly oblique to shell axis, white; peristome expanded (mostly in basal and umbilical direction) but not reflected; parietal callus weak, only indicated by fine whitish calcareous layer, which is transparent in fresh shells; umbilicus open, moderately wide to rather narrow, showing all whorls.
