Found at one station on Cabo Delgado. Two shells (2.7× 1.4 mm ) were collected by van Hoepen ( van Bruggen 2006: 124) on Ilha Vumba only 49 km south of station 7 on Cabo Delgado . Prior to that, perissodonta was known only from south-eastern Mozambique , Swaziland and north-eastern KwaZulu-Natal where it is quite common. The type , described from the area near Maputo, is larger than illustrated here, but the shells from northern KwaZulu-Natal vary from 3.2×1.7 to 6.2× 2.5 mm (van Bruggen 1969: 47 ) .
