Description. Male. Body medium-sized. Fastigium verticis narrower than scape of antenna, divided into 2 conical tubercles, bases of tubercles drawn together, apices separated, obtuse, directing forward (Fig. 12B–C). Eyes oval, protruding forward; median ocellus oval, located between antennal sockets; lateral ocelli nearly circular, situated on lateral margins of conical tubercles of fastigium verticis (Fig. 12A–B). Apical segment of maxillary palp longer than subapical one, apex inflated.

Anterior margin of pronotum rather straight, posterior margin slightly protruding backward; lateral lobe longer than high, anterior and posterior margins straight, ventral margin arc-shaped (Fig. 12B–C). Posterior margin of mesonotum protruding backward. Posterior margin of metanotum slightly straight.

Fore coxae with 1 small spine; femora unarmed on ventral surface, internal genicular lobe with 1 small spine, external genicular lobe with 1 long spine; tibiae with 2 inner spines and 2 outer spines on ventral surface, apices with 1 outer spine on dorsal surface and 1 pair of spines on ventral surface, between the paired ventral spines with 1 small spine. Middle femora unarmed on ventral surface, internal and external genicular lobes with 1 long spine respectively; tibiae with 2 inner spines and 2 outer spines on ventral surface, apices with 1 pair of dorsal spines and 1 pair of ventral spines, between the paired ventral spines with 1 small spine. Hind femora with 11–16 inner spines on ventral surface; tibiae with 31–36 inner spines and 33–35 outer spines on dorsal surface, arranged in average, subapices with 1 pair of dorsal spines, apices with 1 pair of dorsal spines and 2 pairs of ventral spines, interiodorsal spine slightly shorter than hind basitarsi; hind basitarsi with 2–3 dorsal spines (Fig. 12F).

Posteromedian process of 7th abdominal tergite extremely long and straight, obviously surpassing apex of paraproct, apical area of posteromedian process dichotomous, apex obtuse, slightly inflated (Fig. 12D–E). Paraproct rather long, basal half slightly broad, narrowing to apex, apex obtuse, directing dorso-backward (Fig. 12D). Epiproct nearly triangular, apex obtuse. Cerci slender, conical, apices acute (Fig. 12D).

Female. Unknown.

Coloration. Body brown. Lateral margin of fastigium verticis yellowish-brown, eyes yellow. Flagellum of antenna yellow. Face with 4 longitudinal black stripes, both sides of clypeus with 1 black spot respectively. Apices of all femora black, outer margin of basal half of hind femora with yellowish-brown stripes, spines of hind femora and tibiae black.
