Type material.

Type ♂, [SENEGAL], Dakar, IFAN 1952, 31. VII. 1952, A. Villiers, preparation N ° IFAN 2 CH. Rungs P. (MNHN) .

Diagnosis.

(See also the identification key of calamistis species subgroup, section 3.3. 2.). This species can be distinguished from the other known members of the calamistis subgroup by the combination of the following characters of the male genitalia: vinculum u-shaped at the outer margin, w-shaped at the inner margin with an indentation, with a large saccus; apical extension of the sacculus very short compared to the cucullus; juxta pointed inferiorly, the sides rounded, the superior plate bifid; vesica with a semi-circular large cornutus.
