Discussion. Camras (1962a) gives characters that distinguish this species from the other described Afrotropical Thecophora as follows: (1) Veins black to the very base., (2) Legs black, yellow on basal half of posterior femur, [and] basal one third of middle femur, (3) In some views the dorsum is faintly white pollinose, leaving two very fine black longitudinal stripes on the anterior half., and (4) Theca yellow, black on apical margin; relatively large, wider in the middle than at base. The holotype of this species is deposited in the MRAC and has been checked by the author. This species can easily be confused with small dark Thecophora pilosa which have a dark wing base and completely black fore and middle legs.
