Genus Kazakhstania Librovitch, 1940 View in CoL
Type species
Gattendorfia (Kazakhstania) karagandaensis Librovitch, 1940: 68 ; original designation.
Genus diagnosis
Genus of the Gattendorfiinae with a small, thinly discoidal to pachyconic conch with low coiling rate (WER = 1.50–1.70); all stages evolute, with depressed whorl profile. Shell surface often with constrictions on the outer flank and venter. Suture line with deep, lanceolate or slightly pouched external lobe, which is much deeper than the adventive lobe.

Remarks
Kazakhstania is easily distinguished from the other genera of the subfamily Gattendorfiinae because of the very wide umbilicus and the depressed whorl profile in all ontogenetic stages. Another distinguishing criterion is the very deep external lobe, which is usually one and a half to two times as deep as the adventive lobe.
