Three well-differentiated post-sutural dorsocentral bristles. Apical scutellar bristles present. Legs dark brownish. Abdomen with golden and silvery pollinosity, T5 with golden pollinosity. T1+−3 with 2 pairs of lateral marginal bristles, T4 with 1 pair of median marginal and 3 pairs of lateral marginal bristles. ST5 with deep median cleft with margins almost parallel and with pilosity. Cercus straight in lateral view, with pointed apex. Cerci with distal third narrower than middle part in posterior view; parallel. Pregonite and postgonite both with expanded base, gradually narrowing to apex, which is darker than base. Distiphallus with smooth ventroapical margin, rounded apex, lateral expansions, straight dorsal outline, lateral lobes and a dorsoapical “fold” (hoodshaped juxta).
