Head, thorax, and outer sides of legs pale to dark greyish brown, inner sides of femora and tibiae yellow; tegulae with a single black spot basally.

view on leftside of vinculum and valva, lateral view inner side of right valva tegumen/uncus, dorsal view aedeagus with vesica everted
Uncus very small, short, triangular, distally with a small, narrow tip. Valvae large, oval-shaped, distally rounded, outer surface with long, extrusible, tube-like coremata; inner sclerotized process short, curved, and distally blunt, with 3-6 larger spines along the outer side. Vesica medially with two areas of many small, parallel cornuti; the larger area with two larger, slightly curved, and numerous smaller, straight cornuti, the other smaller area with many medium-sized straight cornuti.
Distribution
West, Central, and East Africa; from Sierra Leone to Cameroon, Gabon, and Angola, Zaire, and western Kenya.
Comments
In several of the male specimens examined from Zaire, Uganda, and Kenya the fw ground colour is paler grey, but this might also be due to old age. The status of the type material of subvitrea is given by Goodger & Watson (1995: 4) as syntype(s), but the description by Bartel (l.c.) is clearly based on a single male specimen which therefore must be regarded as holotype.
