Microdrillia sansibarica
Microdrillia sansibarica is a species of sea snail, a marine gastropod mollusk in the family Borsoniidae.
According to Kilburn this species may be a synonym of Microdrillia patricia, but appears to have a more produced base and to lack a basal cord on early whorls.
According to Tucker, Bela sansibarica Thiele, J., 1925 is a synonym of Bela chuni Thiele, 1925.
