Diagnosis. This species is described from a single male from Knysna, South Africa, identified by Razowski (2015) as Afroploce mabalingwae . It is superficially and morphologically extremely similar to other congeners, G. scabellana in particular, but can be distinguished by the exaggerated distal portion of the phallus.

Description. Head: Brown; posterior half of labial palpus black. Thorax: Brown-gray, tegula brown proximally. Forewing length 8.0 mm; forewing ground color mixed gray and brown, grayish near costa, with some faint refractive bluish spots, suffusions and spots brownish and blackish ( Fig. 8 ). Fringe gray, blackish terminally. Hindwing pale brownish cream above; fringe cream; male under side with irregularly ovoid patch of brownish gray secondary scales near middle of wing. Abdomen: Male genitalia ( Fig. 24 ) with uncus short-triangular; socii fused to tegumen; valva broad to middle with short, small hairy lobe at basal edge of basal cavity; sacculus terminating in rounded flange, with long group of dense setae (Spc 1) above ventral edge, two stout spines at base of cucullus; cucullus moderately uniform in width, slightly narrowing postmedially; phallus moderately broad, short; vesica with one large and two smaller cornuti. Female unknown.

Type. Holotype ♁, South Africa, Western Cape Province, Knysna , 5 Feb 1966, G. Bassi, slide Bassi 6441 ( GBC).
