Protarsomere 1 as long as 4 (in holotype, or slightly shorter (7:8, in specimens from Cameroon, Djarengol). Enlarged claw ( Fig. 201C ) with one small subapical tooth and few bristles or four peg-like setae. Protarsomere 5 ( Fig. 201C ) with inner proximal serrate region and one row of 16 lamellae or two rows of 1 (proximal) + 12–14 lamellae (extending beyond 0.5 × length of protarsomere); apex with approximately 9–11 lamellae. Tibial spurs 1/0/1.

♂. Fully winged; body length 1.1–1.6 mm. Head black, except mandible testaceous; antenna brown; mesosoma and metasoma black; legs brown, except tarsi, protibia and articulations testaceous.
