Antenna clavate; antennomeres in following proportions: 15:7:47:29:22:16:13:12:9:12. ADOs present in antennomeres 6–10. Head flat, dull, granulate and sculptured by small areolae and irregular keels; frontal line complete; occipital carina incomplete, only present behind and on sides of lateral ocelli, laterally not reaching eyes; lateral ocelli situated in front of virtual straight line joining posterior edges of eyes; posterior margin of vertex weakly excavated; POL = 3.5; OL = 4; OOL = 10; OPL = 1; temple absent; greatest breadth of lateral ocelli longer than OPL (3.5:1). in specimen from Central African Republic, 03°00’27’’N 16°11’55’’E, head weakly excavated. In specimen from Zambia, Chati, POL = 4, OL = 4. Pronotum crossed by strong anterior transverse impression and strong posterior transverse furrow; disc humped; posterior collar very short; pronotum granulate and sculptured by numerous longitudinal keels and striae (pronotum punctate, unsculptured among punctures in specimen from Central African Republic, 03°00’27’’N 16°11’55’’E); pronotal tubercle not reaching tegula. Mesoscutum of holotype shiny, completely sculptured by numerous irregular, parallel and longitudinal keels. In specimen from Zambia, Chati, median region of mesoscutum reticulate rugose. Notauli apparently complete and posteriorly separated, hardly visible among longitudinal keels. Mesoscutellum and metanotum shiny, smooth, punctate, without sculpure among punctures (granulate in specimen from Central African Republic, 03°00’27’’N 16°11’55’’E). Metapectalpropodeal disc dull, without transverse keels, reticulate rugose and sculptured by few longitudinal keels (completely reticulate rugose in specimen from Central African Republic, 03°00’27’’N 16°11’55’’E), slightly longer than propodeal declivity (15:10); propodeal declivity reticulate rugose, without longitudinal keels.
