1992  Wangrenoceras Yang & Yang: 600.

Type species: Wangrenoceras rotalarium Yang & Yang, 1992, p.600; OD.

[ Yang & Yang, 1992, p. 603.]:  Shell small to medium in size, convolute to moderately evolute, discoidal. Venter broadly
arched with remarkable medial keel. Lateral sides marked by moderately prominent transverse ribs, terminating with
nodes on the ventrolateral part. Umbilicus wide and shallow. Suture line gastriotic, with wide and short ventral lobe
divided by a low medial saddle into two short acuminate prongs, and two pairs of lateral lobes.

This genus is similar to Liuchengoceras in the shape of conch and the surface ornamentation, but the latter has rather
long ventral lobe, narrowly acuminate prongs and narrowly arched venter and acute keel.]
