pectal-propodeal complex with lateral and posterior areas ecarinate. Metasoma (Figure 174). Tergal process with deep, subcircular and sublateral pair of depression, 0.66 x as long as tergite II, diverging posterad, with thin, small and long setae on lateral area; each depression with large tubercle on its center, evenly wide in longitudinal section, very low, entirely dorsad, with broad pit on top, with small tuft of setae dorsad. Hypopygium (Figure 265) with median stalk 1.16 x as long as hypopygial plate; lateral stalk triangular; posterior margin strongly concave. Genitalia (Figures 517-519). Basiparamere small. Paramere with ventral margin excavated. Aedeagal dorsal body with apex higher than parameral apex, evenly wide.
