One of the most widespread Amerila species, known from 14 countries in sub-Saharan Africa. In Cameroon, it was recorded from Southwest and Northwest Provinces. On Mount Cameroon, A. niveivitrea was recorded only between 1100 and 2200 m a.s.l. ( Fig. 1 View FIGURE 1 ).

Female genitalia (Fig. 28)

Papillae anales subsquare, terminally covered with dense setae; a pair of elongated membranous protuberances ventrally, anteriorly from the oviduct; protuberances distinctly wide and shallow proximally, then gradually tapering and more conspicuous distally; anterior apophyses moderate length, straight, not triangular; apophyses posteriores of the same width, 50 percent longer than the anterior apophyses; dorsal and ventral pheromone glands reduced; sternum VIII moderately sclerotized with a pair of small, rounded protrusions raised towards the median line of the body; ostium bursae wide, sclerotized; ductus bursae much shorter than its width, membranous; corpus bursae forming an irregular, ovoid, densely plicate pouch with several small, spiny, heavily sclerotized signa; single, elongate near the origin of the ductus seminalis and several minute sclerotizations forming an irregular line in the proximal section of corpus bursae; ductus seminalis narrow, originating from the slightly convex medio-lateral portion of the corpus bursae.


Female genitalia were briefly described in Häuser & Boppré (1997), but have not been illustrated anywhere yet.
