Palpal formula 6/3. Pronotum, crossed by strong transverse impression, shiny, with anterior collar and disc slightly granulate. Mesoscutum less than twice as long as broad, shiny, sculptured by longitudinal keels, laterally without pointed apophyses ( Fig. 242C ). Mesoscutellum shiny, smooth, sloping anteriorly. Metanotum short, excavated behind mesoscutellum ( Fig. 242B ). Metapectalpropodeal disc shiny, unsculptured; propodeal declivity, mesopleuron and metapleuron transversely striate.
