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.
