Type species. Gynandrotilla ferruginea Arnold, 1946 , ♁, by original designation.

Diagnosis. MALE. Apterous. Mandibles acute apically, with preapical tooth, beneath deeply excised. Clypeus raised in the middle, concave transversely on each side of the middle, the apical margin angularly emarginate in the middle and arcuate on each side. Head wider than mesosoma, vertex long. Eyes with small sinus on inner margin, not reniform. Antennae 13-jointed; flagellum elongate and filiform, F1 short, other ones longer than wide, apical flagellomere transversely compressed. Ocelli well developed. Mesosoma not constricted at sutures, all of which clearly defined; pronotum marginate in front and at the sides, the hind margin angular; tegula fairly large, hirsute; hind margin of the mesonotum transverse, not extending beyond tegula, its posterior corners produced into oblique teeth truncated at the apex. Lateral margins of the nearly flattened scutellum raised; metanotum short but distinct. Propodeum unarmed. T1 not transverse, widened gradually caudad, joining T2 on its cephalic aspect, the anterior angles at its base dilated and directed a little outwards. T7 fairly flattened, wider than long, the apical margin transverse. S1 with a median carina ending caudad in a tooth. S8 (hypopygium) marginate at the sides, feebly concave, its apical margin transverse. Claws unarmed. FEMALE. Unknown.

Diversity and distribution. Only the type species, based on the male sex only, is known from Zimbabwe, Botswana and South Africa .

Remarks. In southern Africa, this is apparently the only wingless male mutillid with ovate and deeply emarginate compound eyes and a strong ventral mandibular tooth.
