Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| D.K. Pandey et al. 2012 | Shells small, incomplete, moderately evolute, planulate, compressed. Whorl section with slightly arched lanks and venter (Fig. 48A, B). Ornamentation consists of very ine, numerous, lexiprorsiradiate primary ribs bifurcating slightly below the distinct ventrolateral shoulder (Fig. 48C, D). Secondaries cross the venter with forward-directed convexity. Occasionally a single, undivided primary rib on one side is connected with a secondary rib on the other side (leading to “galloping” of secondaries). Constrictions present, indistinct. |
