First four antennal segment in a ratio of 25:8:15:14, segment III 3 X as long as thick, segment XI 4.5 X as long as thick. Eyes glabrous. Frons polished, with few punctures at central area of frons. WH 1.0 X LH; WF 0.56 X WH; WF 1.1 X HE; OOL 1.1 X WOT; posterior ocellus distant from the crest vertex 0.75 X DAO; frontal angle of ocellar triangle acute. Vertex entirely rounded, occipital carina visible in dorsal view. VOL 0.52 X HE.

Mesosoma ( Fig. 17 ): thorax polished. Pronotal disc with anterior transverse carina. Notauli well impressed, incomplete anteriorly, nearly reaching in the posterior margin of the mesoscutum. Parapsidal furrows well impressed, incomplete anteriorly. Propodeal disc 1.07 X as wide as long, polished except the basal triangle, with median carina nearly complete, lateral of propodeum polished, declivity strigulate.

Metasoma: petiolate. Genitalia ( Fig. 19 ): paramere short, 0.58 X as long as the basiparamere, apical margin with strongly concave, apical inner portion large and with the upper margin irregular and slightly shorter than the outer corner, the latter rounded; volsella with the ventral ramus of digitus high, 0.52 X as long as paramere, wider apically, with upper margin truncate with rounded corners; aedeagus with a pair of high apical lobes, ending very sharply and slightly directed downward.
