(Figs 5, 28)
Holotype female with labels: 1) Holotypus; 2) Ghana, Northern Region, Banda-Nkwanta, 150m, 08°22’N 02°08’W, Dr. S. Endrödy-Younga [legit]; 3) N[umbe]r 71, light trap, 5-8.IX.1965; 4) GS 5472 GB, 5) Ancylogastra endroedyi Bassi, Holotype, G. Bassi det. Deposited in HNHM.
Diagnosis. In size, A. endroedyi sp. n. (Fig. 5) is similar to A. amphiaula (Fig. 1), but it has a yellowish white ground colour in contrast to the greyish white ground colour of A. amphiaula. The female genitalia of A. endroedyi sp. n. (Fig. 28) are similar to those of A. amphiaula (Fig. 25) and A. magnifica sp. n. (Fig. 27), differing in the more rounded papillae anales, the poor sclerotisation of abdominal segment VIII, the slender and strongly bifid lamella antevaginalis of the sterigma and the smaller lateral extension of the ductus bursae with its shaft only half sclerotised.
Etymology. Named after Sebestyén Endrődy-Younga, collector of many, very valuable entomological specimens throughout Africa.
Description (Fig. 5). Wingspan 27 mm. Labial palpi four times as long as eye diameter, brown with upper half white. Maxillary palpi subtriangular, dark brown tipped white. Antenna simple, off-white with costa bronze brown. Frons rounded, moderately produced, white. Ocelli and chaetosemata poorly developed. Vertex white. Tegulae and thorax brown. Forewing ground colour yellowish white with scattered brown scales; with subrectangular dot in cell; brown stripe dividing in thinner stripes after cell; subterminal fascia narrow, angled at apex, silvery white bordered pale brown; terminal line brown; seven brown subterminal spots; apex rounded; termen slightly oblique; fringe pale grey with short scales white tipped brown; underside white strongly suffused with yellow brown. Hindwing bright white with light yellow suffusion; fringes concolorous; underside white with costal yellow brown suffusion. Legs bronze brown. Abdomen white.
Male unknown.
Female genitalia (Fig. 28). Papillae anales rounded, weakly sclerotised. Apophyses posteriores basally rounded, then narrow and apically slightly curved. Abdominal segment VIII subrectangular, poorly sclerotised. Apophyses anteriores slightly longer than apophyses posteriores, strongly sclerotised basally, narrow, slightly curved. Sterigma with lamella antevaginalis strongly bifid. Ostium bursae membranous. Ductus bursae longer than corpus bursae, with wrinkled sclerotisations basally, then wrinkled and partially scobinate; lateral extension longer than ductus bursae, with shaft narrow and partially sclerotised with distal sac sponge-like and lightly sclerotised. Corpus bursae suboval, membranous with rows of scobinations basally and medially.
Distribution. Only known from Ghana.
