Diagnosis

Moderately small; head mostly yellowish-orange with vertex, frons and occiput dark brown to black; mesosoma dorsally black and ventrally yellowish-orange; metasoma mostly dark brown to black; head granulate to coriaceous with some isolated punctures; inner margins of eyes slightly convergent ventrally; clypeus transverse, long; malar line moderately short; occipital carina joining hypostomal carina strongly above mandible base; antenna with 31 flagellomeres, penultimate flagellomere slightly elongate; mesosoma moderately elongate, entirely coriaceous but ventral half of speculum smooth; area superomedia elongate; apical half of metasomal tergite 1 finely punctate-reticulate, tergite 2 aciculopunctate, following tergites coriaceous; female femoral tooth strong, slightly higher than basally wide, followed by a row of denticles; ovipositor short and straight, apically slightly sinuous. B 5.7; A 3.5; F 3.8; CT 1.7; ML 0.5; POL 1.0; OOL 1.3; Fl n–1 1.2; ASM 2.2; OT 1.3; FFT 2.

Differential diagnosis

Rather small, yellowish-orange and black species from the Seychelles Islands; readily differentiated from all other Afrotropical species by the colour pattern with the mesosoma dorsally black and ventrally yellowish-orange, the coriaceous mesoscutum, the strong femoral tooth and the short ovipositor.
