Nyika Range; 12.5× 6.5 mm).

A common eastern African species, with a general distribution in Tanzania, Malawi and Mozambique. Found at four stations inland. Can easily be separated from juveniles of Kempioconcha by its non-ribbed apex. Differs from other Subulinidae in the area by the pronounced axial sculpture on the teleoconch and by the relatively large body whorl.
