Amerila roseomarginata (Rothschild, 1910) (Figs 14, 29)

Material (1 specimen). 1 ♂ Mount Cameroon (SW slope), 1.ii.2016, PlanteCam camp (1,100 m a.s.l.), N 4.1175°, E 9.0709°, lgt. V. Maicher, Sz. Sáfián, Š. Janeček, R. Tropek (attracted by light) .

Distribution

A very common species frequently collected across equatorial Africa. It is sparsely distributed from the Ivory Coast to the eastern regions of Kenya and Tanzania with some gaps most probably caused by the insufficient faunistic exploration in many countries. The present record (Fig. 14) is the first one for Cameroon, suggesting that the species might have a continuous range in tropical Africa. On Mount Cameroon, only a single specimen was collected at 1150 m a.s.l. ( Fig. 1 ).

Female genitalia (Fig. 29)

Papillae anales subsquare, terminally covered with sparse setae; separated ventrally by a pair of elongated mem- branous protuberances, anteriorly from the oviduct; anterior apophyses moderate length, straight; apophyses poste- riores narrower, one-third longer than anterior apophyses; dorsal and ventral pheromone glands reduced; sternum VIII sclerotized, forming a pair of prominent, flat, subsquare protrusions; ostium bursae wide, membranous; ductus bursae much shorter than its width, membranous; corpus bursae forming an irregular pouch with two sclerotized, flat surfaces in the proximal section and extensive irregular signum bursae with numerous, sharp, elongate spines in the distal section, terminating in a small, papilla-like appendix bursae; ductus seminalis narrow, arising from the anteromedian portion of the bursa.

Remarks

Female genitalia have neither been described nor illustrated before. The species identity of the collected specimen is confirmed by the key characters of imago provided by Häuser & Boppré (1997).

The weighted mean elevation of individual species (black dot), together with their lowest and highest records, are visualized. After species names, numbers of collected specimens are stated.
