Face+clypeus 1.0 × as wide as long; labrum not exposed when mandibles closed; malar space 0.6 × as long as basal mandibular width; lateral ocellus separated from compound eye by 0.9 × ocellar diameter, distance between ocelli 1.5 × maximum ocellar diameter; head posteriorly behind ocellar triangle flat; gena, on lateral view 1.0 × as long as compound eyes; occipital carina absent ventrally; antenna with 34 flagellomeres, ratio of length from second to fourth flagellomeres: 1.2:1.1:1.1, subapical flagellomere 1.3 × as long as centrally wide.
MESOSOMA. Epicnemial carina complete; metapleuron with dorsal margin evenly declivous, polished with isolated setae; submetapleural carina smooth, anteriorly expanded into a conspicuous lobular lobe. Propodeum with lateromedian longitudinal carina strong, slightly closer subbasally; lateral longitudinal carina weak but discernible, absent anterior to spiracle; posterior transverse carina complete.

COLOR. Head extensively black except palpi and face+clypeous yellow and tawny orbits from posterior ocelli to gena. Mesosoma predominantly black except propodeum dorsally, mesoscutum (except three brownish black vittae) and scutellum reddish tawny (except anteriorly brownish); tegula yellowish; prolegs brownish black except trochanter distally, femur basally and distally, tibia, and, tibial spur yellowish, and tarsomeres (except, distal third of basitarsomere, and tarsomeres 2–4 yellowish brown) yellowish; mesoleg brownish black except trochanter distally, femur basally and distally, and tibia dorsally yellow; mesotibia ventrally and mesotarsomeres brownish yellow; metaleg brownish black except reddish tawny spot posteriorly in coxa, femur basally and distally, and tibia dorsally yellow; meso- and metatibial spur whitish; and, ovipositor valvae testaceous; wings slightly infuscate; metasoma brownish black with tergites grading posteriorly and laterally to reddish brown.
