Thorax ( Fig. 452 ) with slightly transversely elongate, polygonally reticulate sculpture on pronotum that is generally of similar mesh size, but conspicuously shallower than that on frontovertex; mesoscutum with polygonally reticulate to imbricate-reticulate sculpture that is of slightly larger mesh size than that on frontovertex and clearly shallower; axilla with similar sculpture to mesoscutum, but slightly deeper; scutellum with conspicuously deeper and coarser sculpture than that on mesoscutum, but of similar mesh size, apical 0.3X and side with progressively shallower sculpture; visible part of mesoscutum about 1.9X as broad as long; scutellum about 1.1X as long as broad; setae on mesoscutum moderately dense, separated by a little less than their own lengths and of more or less uniform length, those on scutellum of similar density, but clearly longer especially towards apex; fore wing with venation and setation as in Figs 450, 451 ; propodeum ( Fig. 452 ) medially with some irregular, very shallow sculpture medially in posterior half; setae outside spiracle extending towards posterior margin, but not down side.
