( Figs 25–29 View FIGURES 17–29 )

Description. Male. Head and mesosoma black; metasoma dark castaneous. Mandible with four apical teeth; median clypeal lobe trapezoidal, broadly like duckbill, high in lateral view, median tooth rounded; frons coriaceous, punctate; eyes glabrous; antenna with moniliform flagellomeres; gena with one pair of spines. Notauli absent; pronotal disc weakly coriaceous; metasomal tergite II with tergal process with subrounded lateral depression, tuft of setae, most lateral one directed outward, distinctly longer than others. Posterior hypopygeal margin straight. Genitalia: paramere with rounded apex, strongly arched inward, very constricted, very wide basally, higher than the basiparamere, few, long bristles present; aedeagal ventral ramus shorter than dorsal body, apex narrow, laminar; aedeagal dorsal body with one pair of apical lobe, long, weakly curved dorsally, ventral margin weakly serrated, membranous; basal process absent; apodeme not extending beyond genital ring. Female unknown.

Remarks. This species belongs to the gilvipes species-group by having metasomal tergite II with a lateral tergal process, the tufts of this tergal process have most lateral setae distinctly longer than the others. It is not similar to other species of its species-group. This species is mainly different because it has the median clypeal lobe trapezoidal, broadly like a duckbill, the gena with one pair of spines, and the paramere with a rounded apex, that is strongly arched inward and very constricted.
