Description: Coloration typical of group, katepisternum and meron very slightly infuscate and pollinose; tergite 6 lighter than preceding segments, epandrium and cerci darker. Setation as in diagnosis and measurements. Protarsal spines with typical array of 8 fang-shaped spines alternating in size, 4 on each on two basal tarsomeres. Male genitalia: Hypandrium with narrowed anterior end, width 0.5x the posterior end; phallus in dorsoventral view gradually broadened subapically to at least twice the width of phallus shaft. Like cameroonensis , without coarse or fine scales, only minute pimpules apically, short, dense spicules medially; aedeagus best distinguished from cameroonensis in lateral view, freidbergi being larger and much thicker ( Fig. 12h , cf. fig. 12e).
