Mesoscutum with strong reticulation on sidelobes, meshes isodiametric; midlobe with a mix of strong reticulation with elongate meshes and with longitudinal carinae, with a strong and complete median groove, and with four adnotaular setae in a single row; notauli very strong, distinct and smooth. Mesoscutellum with weak reticulation, meshes elongate; submedian grooves distinct, straight and parallel; with two pairs of setae on lateral parts, one pair at posterior margin and one pair situated slightly behind middle of mesoscutellum close to axillular groove; frenal groove very wide and subdivided by carinae with median carina especially strong. Dorsellum with strong reticulation, with median carina. Propodeum with a strong narrow median carina; with strong reticulation; callus with two setae. All coxae with weak reticulation and shiny. Fore wing with seven setae on dorsal surface of submarginal vein; speculum closed; costal setal row broken. Petiole transverse with strong longitudinal carinae.
