Originally described from the Mediterranean, this species has recently been mentioned from Tenerife, Canary Islands, by Nofroni & Tringali (1995). Our shells also originate from the Canary Islands. This species is not known from the Cape Verde Islands, but two more or less similar taxa, viz. O. dalsumi spec. nov. and O. prinsi spec. nov. are reported from that region.
