Type species: Pronorites cyclolobus var. uralensis Karpinskii, 1889, p. 8 [OD].

[Nassichuk, 1975, p.54: Stenopronorites is extremly involute and characteristically has flattened sides and a
rounded venter. In early growth stages, the ratio of whorls height width approximately unity but at maturity the
whorl height is twice the whorl width. The shell is smooth but faint ribs may be present on the venter
and ventrolateral flanks.
 
The suture has 6 or 7 lobes or less between the ventral lobe and the umbilical seam and 2 to 4 internal lobes in
addition to the dorsal lobe for total complement of 18 to 24 lobes. The first lateral lobe is divided into two more
or less equal subdivisions by a moderately high saddle with diverging flanks].

A:   Conch discoidal, very or completely involute, with shallowly rounded ventral side. Umbilicus moderately narrow to narrow.
B:   Surface of conch smooth.
G:   18 - 24 lobes, first umbilical wide, symmetrically bifid.

[Ruzhentsev & Bogoslovskaia, 1971, p.148: Megapronorites shows asymmetrical subdivision of first umbilical lobe leading to Uralopronorites. Stenopronorites symmetric bifid first umbilical lobe, with saddle increasing height.]
