Head black, except mandible and clypeus ferruginous; propleuron black; pronotum black, except margins and posterior collar reddish; rest of mesosoma black; metasoma black-brown, some× with apex reddish; legs testaceous, except coxae and clubs of femora black or brown. Antenna clavate; antennomeres in following proportions: 16:6:27:19:14:11:9:9:8:10. Head shiny, completely reticulate rugose; occipital carina complete; OL shorter than POL; OPL shorter than OL. In specimen from Kenya, 00°61.517’S 34°09.200’’E, POL = 6; OL = 5; OOL = 11; OPL = 2; temple absent; greatest breadth of lateral ocelli longer than OPL (3:2). Pronotum dull, granulate, not humped, crossed by slight anterior and posterior transverse impressions; posterior collar short, slightly visible; pronotal tubercle not reaching tegula. Mesoscutum dull, granulate and reticulate rugose. Notauli absent. Mesoscutum with two longitudinal keels on place of notauli and reaching approximately 0.5 × length of mesoscutum.
