Redescription. The description by Horvath, 1913 was obviously based on female specimens, as syntypes from Cameroon are mentioned from “Mus. Berolin. et Hung.” and from Congo (Regio Chari) from “Mus. Paris”. The female from Zool.Museum Berlin is here designated as lectoptype.

Based on Horvath’s Latin description and additional data for the male, a redescription is given below.

Male. Body oval, coloration ochraceous, darker brown to black are head, pronotum and triangular base of scutellum, base of antennal segments I+II, basal 2/3 of femora, 2 anterior tubercles of deltg II–VII, 3–4 anterior tubercles of lateral carina of mtg III–VI and row of tubercles on lateral margin of scutellum along deltg III+IV; whitish are antennae, legs and basal and pre-apical pattern of scutellum.

Head. Slightly longer than wide; clypeus oval beset with larger erect tubercles reaching apex of antennal segment III; antennae slender about as long as width of head, segments I–III cylindrical of subequal length, IV barrel-shaped nearly as long as preceding ones with distinct plaques; eyes oval; postocular lobes with lateral tooth, vertex with 2–3 rows of larger tubercles, laterally depressed and delimited by row of tubercles along inner margin of eyes. Rostrum arising from open atrium, as long as head.

Pronotum. Sinuate lateral margins beset with row of round tubercles, anterolateral ones more prominent; disk with 2 ring-shaped granular carinae on posterior lobe, their inner carinae continuing as rows of tubercles reaching anterior margin.

Scutellum. Triangular elevated base densely tuberculate; median carina with spaced round tubercles; lateral margins excised for exposed rim of corium with row of erect tubercles reaching to posterior margin of deltg IV; surface with tingid-like reticulation and brownish pattern.

Abdomen. Deltg I carinate and elevated; lateral margins of deltg II–VII rounded and beset with double row of 4 dorsal and 5 ventral tubercles; tergite VIII of male exposed, cup-like and triangular-shaped posteriorly.

Venter. Surface finely granulate with few sub-lateral tubercles on vltg V–VII; spiracles II–VI ventral, VII lateral placed on tubercle of lower row; sternite VIII exposed, crescent shaped, posterolateral apices bearing spiracles VIII barely visible in dorsal view.

Pygophore. Oval, surface granulate.

Female. Of larger size; tergite VIII sub-rectangular, carinate at middle, posterior margin with 3 larger tubercles; tergite IX+X truncate, produced posteriorly; ptg VIII consisting of cluster of tubercles, one of them bearing spiracle VIII, without connecting sclerite.

Measurements. Male / female: Length 4.1/ 4.4mm; length of antennae 0.85/ 0.9mm; ratio length of antennae / width of head 1.03/1.028; ratio head length/width 1.03/1.08; ratio pronotum w/l 1.76/2.0; ratio scutellum l/ w 1.42 / 1.34; width of abdomen 1.55/ 1.55mm; length antennal segments I/II/III/IV = 3/3.5/3.5/6 and 4/4/4/6.

Distribution. So far recorded from ( Kamerun) Cameroon ( Horvath 1913), Chari Region in Central African Republic ( CAR) ( Horvath 1913), Togo and Cote d’Ivoire in Westafrica (this paper); Yangambi and Lomani in Democratic Republic of Congo ( DRC) (this paper) and Congo Lembo ( Schouteden 1919) ( DRC near the border of CAR).
