Redescription.

Male: medium size, integument rugous; head conical and oblique; fastigium of vertex short with obtuse apex; eyes prominent and globose; antenna, filiform longer than head and pronotum combined; pronotum without lateral carinae and with straight median carina, crossed by three sulci, its anterior and posterior margins rounded and incised in the middle; pale basal band of lateral lobes of pronotum narrowed in front of second transverse furrow but not interrupted; longitudinal median band of pronotum disc dark and less wider than adjacent clear bands; prozona longer than metazona; prosternal tubercle conical; anterior margin of mesosternum broadly projected medially; mesosternal space open and longer than it is wide; elytra vestigial or lobiform; median pale spot on inner area of hind femora absent; outer area of hind femora with three pale spots; incipient spots along medio-superior margin at level of outer spots present; dorsal carina of hind femora finely toothed; lower outer areas of hind femora dark, wine-colored; hind tibiae wine-colored; distal half of hind tibiae widened, basal ring present; supra-anal plate subconical, with two digital tubercles near lateral margins; subgenital plate short conical, gradually tapering towards rounded apex; cerci conical, curved inward and without preapical lobule. Epiphallus (Fig. 15 Q View Figure 15 ): bridge narrow, short and arched; ancorae small, close together and with acute apex; lophi short, broad and lobiform; lateral plates broad and rounded; anterior and posterior projections short. Phallic complex (Fig. 15 R – T View Figure 15 ): dorsal arch of the cingulum V-shaped, strongly open not overlying the endophallic sclerites; latero-ventral sclerite broad, subtriangular; zygoma wide; apodemes of the cingulum long, reaching the apex of the endophallic apodemes; lower ectophallic sheath not enveloping the base of the rami; upper ectophallic sheath globular, sloping forward.

Female: Similar to the male but larger; supra-anal plate conical with a transverse groove in the middle field; posterior edge of the subgenital plate projecting; cercus conical with angular apex; dorsal valves of the ovipositor weakly toothed; base of the spermathecal duct widened well before it opened into the copulatory bursa; spermatheca ampulla relatively thin; distal, recurrent trunk of the spermatheca lateral diverticulum> 3 × longer than the proximal trunk.

Remarks.

Pteropera verrucigena was originally described from Barombi station (southwest Cameroon) with some paratypes recorded between Kumba-Mamfé (Southwest Cameroon) by Karsch (1891). We now additionally recorded the species from Sohock (Littoral Cameroon).
