Morphological characters as given in the generic description, and the following:
Head. Ocellar triangle with apical angle slightly acute, OOL, POL, OCL ratios–1:8:4.5; frontovertex with regular, polygonal raised reticulate sculpture, the cells becoming smaller on face; setae silvery white; eye with setae hyaline, each seta shorter than a facet. Relative measurements (holotype, card)—head dorsal width, 35; frontovertex width, 13; head frontal height, 39; eye height, 28; malar space, 10; antennal scape length, 25.
Mesosoma. Pronotum with fine, irregular polygonal reticulate sculpture, the cells transversely elongate; mesoscutum with fine, regular polygonal reticulate sculpture; axilla with slightly raised reticulate sculpture; scutellum with distinct, raised, reticulate sculpture, clearly deeper than on mesoscutum; setae silvery white including those distal to each propodeal spiracle. Relative measurements (holotype, card)—mesosoma length, 53; pronotum length (width), 15 (28); mesoscutum length (width), 17 (31); scutellum length (width), 18 (16); propodeum median length, 6.
