Distribution

One of the most widespread species of the genus, although restricted to the Guineo-Congolian forest zone. Known from Sierra Leone to west Kenya (Kakamega Forest) and northwest Tanzania. On Mount Cameroon, it was col- lected from 650 m a.s.l. up to the timberline ( Fig. 1 ).

Male genitalia (Figs 18–19)

Morphology of the studied specimen does not differ from those presented in Häuser & Boppré (1997).

Female genitalia (Fig. 26)

Papillae anales subsquare, terminally covered with sparse setae; a pair of minute but distinctive membranous lobes ventrally, anteriorly from oviduct; anterior apophyses moderate length, thick, “thorn” like; posterior apophyses narrower, twice as long as anterior apophyses, slightly flattened at apex; dorsal and ventral pheromone glands re- duced; sternum VIII sclerotized, posteriorly evenly emarginated, divided medially by the membranous longitudinal concavity; ostium bursae wide, membranous; ductus bursae very short, membranous; corpus bursae oval, membra- nous, densely plicate; signum in the form of weakly expressed, sclerotized zone in the laterodistal portion of corpus bursae, additionally a pair of weakly sclerotized, narrow, elongate, parallel structures located on the opposite wall of corpus bursae; ductus seminalis slender, with wide entering, originating at the middle of corpus bursae.
