Figs 2, 12, 13, 20

Anomologa demens Meyrick, 1926: 309 . Exotic Microlepidoptera, 3 (10): 309. Holotype (♂), in DMSA (examined).

Type material examined. Holotype of A. demens ♂, “ Slypsteendrift, 28.xii.1924, A.J.T. Janse ” | “ Anomologa demens M., Type No. 813” (DMSA).

Material examined. 2 ♂, same data as for holotype (gen. slide 27/13, O. Bidzilya; g. 4134) (DMSA).

Diagnosis. The species can easily be recognized by the uniformly black forewing and bright orange head that are unique for Anomologa . Other species of the genus have a white forewing with dark fasciae. The male genitalia are characterized by having an elongate, subrectangular tegumen (widened in basal part in rest of Anomologa species) in combination with a short saccus, and a long slender phallus (certainly broader in rest of species).

Redescription. Wingspan 21.0– 22.7 mm (Fig. 2). Head (Figs 12, 13) bright, ochreous brown, labial palpus light brown mixed with black, head, thorax and tegulae uniformly black; hindwing and fringe dark, greyish-black.

Male genitalia (Fig. 20). Uncus parallel-sided at basal part, then weakly broadened, slightly longer than broad, extends to 1/2 length of valva; tegumen elongate, subrectangular, anteromedial emargination broadly rounded, extending to 1/4–1/3 length of tegumen; valva moderately broad, dorsal margin weakly bent inwards in middle, apex rounded; sacculus as broad as adjacent portion of valva, dorsal margin gradually rounded, ventral margin direct to 3/4, then narrowed, apex with short pointed tip, extends to 1/2 length of valva; vinculum slender, band-shaped, juxta lobes broadly rounded, separated by deep V-shaped incision; saccus parallel-sided, weakly constricted in middle, apex weakly concave, extends to top of pedunculus; phallus slender, as long as valva, weakly inflated at base, gradually narrowed to 3/4, apex distinctly broadened, posterior margin straight, subapical tooth triangular, short, broad at base.

Female genitalia. Unknown.

Biology. Adults have been observed in December.

Distribution. South Africa (Limpopo province).

Remarks. Anomologa demens was described based on single male collected in Slypsteendrift, Limpopo Province, South Africa. No additional specimens apart from two males collected in sympatry with holotype (coll. DMSA) were available for study.
