Ventral 0.5 of facial orbit and malar space widely striate. MI 0.9. Mandible with two equal teeth. Genal carina reaching the hypostomal carina far from mandibular base. Mesoscutum with dense coarse punctures apico-medially and laterally; mesopleuron with fine punctures dorsally and almost smooth ventrally; metapleuron with superficial punctures. Area basalis triangular, about as long as wide; area superomedia short, 1.5x longer than wide and 0.8x as long as the area petiolaris, costula in the middle; area petiolaris very large (ca. 0.5x as long as propodeum), 0.95x as long as wide. Hind femur 4.8x longer than wide; hind metatarsus 0.38x as long as the hind tibia; hind claws with one visible basal tooth.
