Head: mandible bidentate. Clypeus trapezoidal. First four antennal segments in a ratio of 27:11:10:10, segment XI 1.5 X as long as broad. Frons strongly coriaceous, punctures large, shallow, separated by 0.5–1.5 X their diameters. LH 1.02 X WH; WF 0.59 X WH; 1.24 X HE; OOL 1.17 X WOT; DAO 0.33 X WOT; posterior ocelli distant from the vertex crest 1.67 X DAO, frontal angle of ocellar triangle acute. Vertex slightly straight, corners rounded. VOL 0.5 X HE.
Mesosoma: thorax strongly coriaceous, with punctated smaller and more distant each other than those of frons. Pronotal disc 0.57 X length of mesoscutum. Propodeal disc 0.6 X as long as wide. Fore femur 3.0 X as long as thick.
Metasoma: tergite II with pair of very shallow lateral depressions, each one with tubercle flattopped, with pit on the top, with dense tuft of long hairs, tubercles slightly closer to the median line than the lateral margin of tergite II. Hypopygium with median stalk 1.4 X as long as plate, posterior margin straight. Genitalia (Figs. 44–45): paramere as long as basiparamere, apex rounded and thin. curved slightly inward, dorsal margin straight and illdeveloped, ventral margin concave above; volsella with cuspis with apex acute, digitus with large basal projection; aedeagus with ventral ramus longer than dorsal body, laminar, surface vertical, angled medially outward, ramus thin with apex wider and rounded in lateral view; dorsal body with two pairs of apical lobes, outer pair angled medially outward, apex with two sharpened teeth directed downward, ventral margin dilated medially (Fig. 46), inner pairs stout, membranous and hairy; apodeme extending beyond the elliptical genital ring.
