Description: Body length: 10.7 mm.
Coloration and pruinescence: Head mainly black except gena and anterior edge of parafacial which are red; head covered with whitish-grey pruinescence. Palpus yellow. Scape and pedicel varying from dark brown to fuscous red. Thorax mainly black; posterior 1/3 of scutellum reddish-yellow; scutum with four presutural dark vittae, lateral vitta subrectangular, indistinctly outlined anteriorly and reaching further forward than strong lateral posthumeral seta. Legs black. Tegula and basicosta black or dark brown. Abdominal tergites 3–5 entirely covered with dense yellowish-grey pruinescence, except on posterior 1/5– 1/6 where pruinescence turns brownish.
Head: Compound eye bare. Arista thickened on basal 1/2 or slightly more. Second aristomere about 7.5 times as long as wide. Thickened part of third aristomere about 1.6 times as long as second aristomere. Postpedicel 6.8 times as long as pedicel. Vertex at its narrowest point 1.13 times as wide as compound eye in dorsal view. Lateral vertical seta weak, scarcely differentiated from postocular setae. Six to seven frontal setae descending below level of base of arista. Frontoorbital plate with one row of medioclinate setae lateral to row of frontal setae. Gena in profile about 0.25 times as high as compound eye. Postocular setae fine, relatively long, bent anteriorly. Prementum about 1.0–1.5 times as long as wide.
Legs: Fore claws and pulvilli at least as long as fifth tarsal segment.
Abdomen ( Fig. 4A View Figure 4 ): Syntergite 1 + 2 with one pair of strong median marginal setae. Tergite 3 with one pair of median marginal setae 1.25 times as long as corresponding tergite. Tergite 4 with a row of 11 marginal setae. Tergite 5 with a row of marginal and discal setae.
Male terminalia ( Fig. 4B–D View Figure 4 ): Epandrium relatively long and convex. Hypandrial arms not bent anteriorly, shorter than medial plate of hypandrium. Distal 1/2 of cerci widely apart and finger-like; basal 1/2 not convex, with a short longitudinal carina bearing long, erect setae. Medial slope of longitudinal carina without brush-like setulae ( Fig. 4C, D View Figure 4 ). Distal 1/3 of cerci strongly bent posteriorly ( Fig. 4B View Figure 4 ). Medial preapical tooth of cerci well developed. Surstylus laterally compressed, paddle-like, strongly curved posteriorly ( Fig. 4B, C View Figure 4 ); surstylus with very few setulae along posterior margin and on basal 1/2 of lateral surface ( Fig. 4B View Figure 4 ).
Hosts: Unknown.
Distribution: Afrotropical: D. R. Congo.
