Metasoma (Figs 2B, 5 E–F). Tergite I 1.64–1.76× as long as posteriorly broad, smooth and shiny, with fine and relatively dense setiferous punctures laterally (Fig. 2B); spiracle near its basal 0.35; lateromedian longitudinal carinae strong, reaching about 0.2 of length of tergite; lateral longitudinal carinae weak, reaching about 0.2 of length of tergite. Sternite I extending back about 0.75 of length of tergite (Fig. 5E). Tergite II 1.00–1.18× as long as posteriorly broad, central region shiny, with fine and sparse setiferous punctures (Figs 2B, 5F); rest of tergites shiny, progressively more densely and strongly punctate.

Colouration (Figs 1B, 5 A–F). Head black with clypeus, face, frontal and vertical orbits, mouth parts except apex of mandibles, malar space and ventral part of gena, white; antenna with scape and pedicel dark brown dorsally, widely white at ventral side, flagellomeres brown, basal flagellomeres whitish on the ventral side. Mesosoma mostly orange, propleuron and postscutellum, white; posterolateral corners of propodeum and posterior part of metapleuron and posterior lower part of mesopleuron sometimes paler; metapleuron with a wide dark brown mark; posterior dorsal part of propodeum brown, posterior rim of propodeum black. Metasoma mostly dark brown, anterolateral marks of tergites I–VI, somewhat extending back, anterior narrow band of tergites III–VI and posterior rim of tergites II–VII, whitish.
