Type species: Megapronorites sakmarensis Ruzhentsev, 1949, p. 61 [OD].

[Ruzhentsev & Bogoslovskaia, 1971, p.141: Conch large, subplatycone.  Whorls moderately
involute, with almost flat ventral side.  Umbilicus is slightly narrow.  Shell surface almost smooth.  
20 lobes in all: a ventral one, eight umbilical lobes, of which two are on the inner side of the
conch, an inner lateral and a dorsal.  First umbilical lobe wide, bifid, somewhat
asymmetrical, because its outer part is larger than the inner part.  Inner lateral lobe
connected to fourth umbilical.] Comparisons: outer part of first umbilical lobe is wider than the inner one at
Megapronorites.
