view on leftside of vinculum and valva, lateral view inner side of right valva tegumen/uncus, dorsal view aedeagus with vesica everted
Male genitalia (Plates). Uncus long and narrow, distally with a small pointed tip ventrally; the tegumen-vinculum area much wider than in other Amerila species. Valvae short and square-shaped, distally not rounded; outer surface without extrusible coremata; inner sclerotized process short and strong, hook-like, distally pointed, and situated inside a membraneous pocket. Vesica medially with a small, plate-like sclerotization, but without any cornuti.
Female genitalia. Bursa copulatrix without signa or other conspicuous sclerotizations.
East and South Africa; from eastern Zaire and western Kenya to Zimbabwe and Zwaziland.
This species had been first discovered by Simon Muller when examining material from TMPR and BMNH, who had given it the name 'alba' in an unpublished graduation thesis (Muller 1980: 65). As a valid description of that name has never been published, we take the pleasure to name this species in dedication to its discoverer. The male genitalia of A. mulleri is fairly distinct from other African Amerila except A. magnifica, and these species probably represent a well differentiated subgroup within the genus.
