The Ants of Africa
Subfamily Myrmicinae

Genus Cyphoidris Weber (1952: 26)

Diagnostic Features - Antenna with 11 segments. Frontal lobes present; pronounced antennal scrobes. Eyes present and forward of mid-length of the head. Anterior clypeal margin unarmed but median portion narrow and bicarinate. Mandible with 10-14 teeth, decreasing in size from apex to base. Promesonotum domed in profile, propodeum bispinose.

Weber's (1952) genus description is at {original description}.

Not in Bolton (1973a) but reviewed by Bolton (1981b). The geographical notes in the latter review, however, are incorrect. First, Bolton described parissa as the only one of West African origin, despite listing an Ivory Coast finding of spinosa. I am including Cameroun, and thus exalta, in "West Africa".
