Mandible with two apical teeth; median clypeal lobe trapezoidal, broadly like duckbill in dorsal view, high in lateral view, median tooth straight; frons strongly coriaceous, punctate; eyes weakly setose. Notauli complete; pronotal disc coriaceous, punctate. Metasomal tergite II with tergal process with one pair of non-conspicuous lateral depressions, tubercle absent, callus present, tuft of setae. Posterior hypopygeal margin straight. Genitalia: paramere with weakly rounded apex, wide; as long as basiparamere; volsella with small basal projection; aedeagal ventral ramus shorter than dorsal body, apex rounded, weakly serrated, laminar, curved ventrally; aedeagal dorsal body with two pair of apical lobes, outer lobe wide, curved ventrally, dorsal margin weakly serrated, ventral margin strongly setose, inner pair membranous; basal process absent; apodeme extending beyond genital ring.

Remarks. This species does not fit other species-groups because it has the clypeus broadly duckbill-like in dorsal view, the metasomal tergite II with the tergal process with one pair of non-conspicuous lateral depressions, without tubercle, but with a callus and tuft of setae.
