carinate. Metasoma (Figure 139). Tergal process with deep, longitudinally elliptical and sublateral pair of depression, 0.58 x as long as tergite II, diverging posterad, with very small and thin setae on anterior area; each depression with very small tubercle on its center, evenly wide in longitudinal section, very low, entirely dorsad, with small pit on top, with small few setae anterad. Hypopygium (Figure 231) with median stalk evenly narrow, 1.3 x as long as hypopygial plate; lateral stalk triangular; posterior margin straight or nearly so and with median elevation. Genitalia (Figures 413-416). Basal margin of paramere with rounded projection. Aedeagal dorsal body with apex as high as parameral apex, evenly wide, narrowing abruptly apicad. Aedeagal ventral ramus with apex as high as aedeagal dorsal body apex; slightly trifurcated forming two sheets, ventral sheet long and smooth, dorsal sheet small and smooth. Genital ring straight, each half straight in dorsal view.

FEMALE: Unknown.
