Differential diagnosis.

This species is similar to B. lakainguta , B. multihami , and B. hooki , but differs from all by the presence of spiral striation on the shell and absence of hooked apertural barriers. Bensonella karoensis is also not spirally striated, is more ovoid with a blunter apex and shallower suture. See also under B. spinosa sp. nov.
