Description. ♀. Apterous; body length 4.2–6.0 mm. Head brown, except mandible, clypeus and most part of frons testaceous (occasionally anterior half of frons testaceous); antenna brown, except antennomeres 9–10 yellow-whitish (in specimen from Mayotte, antenna brown, except scape and flagellomere 8 testaceous); mesosoma black, except lateral margins of pronotum brown-testaceous (in specimen from Mayotte, mesosoma totally black); metasoma brown; legs brown, except tarsi testaceous (in specimen from Mayotte, legs brown, except articulations and part of trochanters whitish, part of meso- and metafemur whitish). Antenna clavate; antennomeres of holotype in following proportions: 13:7:32:16:13:10:10:9:8:14. Head excavated, bare, shiny, finely punctate, unsculptured among punctures; frontal line complete; occipital carina absent; temple distinct; POL = 2.5; OL = 2.5; OOL = 12. Palpal formula 5/3. Pronotum shiny, unsculptured, crossed by strong transverse impression. Mesoscutum shiny, sculptured by many longitudinal keels, with two lateral pointed apophyses situated on sides of margin between mesoscutum and mesoscutellum ( Fig. 180G ). Mesoscutellum sloping anteriorly, shiny, unsculptured. Metanotum sloping anteriorly, shiny, unsculptured, weakly excavated behind mesoscutellum, with two lateral pointed apophyses ( Fig. 180G ); lateral regions of metanotum transversely striate. Metapectal-propodeal disc shiny, strongly transversely striate, except anterior surface unsculptured; propodeal declivity transversely striate. Mesopleuron and metapleuron strongly transversely striate. Meso-metapleural suture obsolete, slightly visible only in posterior half. Protarsomeres in following proportions: 20:4:8:20:33. Protarsomere 3 produced into hook. Enlarged claw ( Fig. 182B ) with one large subdistal tooth and one row of seven lamellae. Protarsomere 5 ( Fig. 182B ) with two rows of 4 + 15-17 lamellae; apex with at least 16 lamellae. Tibial spurs 1/0/1.
