Mesoscutellum with weak reticulation on median part, lateral parts with coarse sculpture; with a very weak median groove; submedian grooves with outer margin indistinct, straight and parallel; with nine scattered setae. Dorsellum with very weak sculpture and shiny, with median carina. Propodeum with a strong median carina that expands posteriorly; with strong irregular carinae and strong reticulation; callus with five setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation. Fore wing with 3&4 setae on dorsal surface of submarginal vein; speculum closed; costal setal row broken.
