Description. ♀. Fully winged; body length 5.0– 5.6 mm. Head black, except mandible reddish; antenna testaceous, except antennomeres 7–10 black; occasionally antenna totally black or brown; mesosoma black; occasionally lateral regions and posterior margin of pronotum reddish; metasoma brown or brown-reddish; legs black, except tarsi testaceous. Antenna clavate; antennomeres in following proportions: 40:14:58:41:28:20:18:14:13:19. Head shiny, excavated, granulate, with many parallel keels on frons, vertex and occiput; occipital carina absent; POL = 14; OL = 6; OOL = 30. Palpal formula 6/3. Pronotum crossed by transverse impression, dull, granulate and sculptured by some striae on collar and around disc; posterior edges of pronotum rounded, not produced into lobes. Mesoscutum dull, granulate and with longitudinal keels. In specimen from Uganda, 01°45’N 31°35’E, mesoscutum with many longitudinal keels crossed by many transverse keels (so mesoscutum apparently reticulate rugose). Notauli absent. In specimen from Uganda, 01°45’N 31°35’E, mesoscutum with two complete longitudinal keels similar to notauli. Mesoscutellum granulate and with many longitudinal keels; in specimen from Uganda, 01°45’N 31°35’E, mesoscutum completely reticulate rugose. Metanotum very reduced and short. Metapectal-propodeal disc reticulate rugose; propodeal declivity reticulate rugose, with two longitudinal keels. Forewing with two dark transverse bands; distal part of 2r-rs&Rs vein approximately 1.4–1.5 as long as proximal part. Protrochanter approximately 4 × as long as broad. Protarsomere 1 longer than 4 (24:14). Enlarged claw ( Fig. 163A ) with one subapical tooth and 11 peg-like setae. Protarsomere 5 ( Fig. 163A ) with two rows of 16 lamellae; apex with at least 15 lamellae. Tibial spurs 1/0/1.

♂. Unknown (see remarks).

Material examined. Type: ♀ holotype: DEMOCRATIC REPUBLIC OF THE CONGO: North Kivu, Loashi Valley , 01°22’S 28°47’E, VIII.1937, J. Ghesquière leg. ( MRAC) .

Hosts. Unknown.

Distribution. Democratic Republic of the Congo, Uganda, Zimbabwe.
