(
Fig. 8
, Map 1)
Male.
Size medium, form slender. Fastigium verticis about 1.6 times as wide as scape, lateral margins not raised. Scape as long as pedicel and first segment of flagellum combined; pedicel as long as first segment of flagellum. Eyes elongate and oval, protruding outwards; median ocellus subcircular, better defined than lateral ocelli (
Fig. 8
A). Anterior margin of pronotum slightly projected in the middle, posterior margin almost straight, 2 low callouses present on each side laterally; lateral lobes longer than high, ventral margin truncate (
Fig. 8
B–C).
Hind
femora with 4–5 inner and 5–7 outer ventral spines; hind tibiae with 7 inner and 6 outer spines on dorsal surface, subapices of ventral surface with 1 inner spine. Tegmina considerably surpassing apices of hind femora, reaching the basal one-thirds area of hind tibiae; hind wings slightly longer than tegmina. Ninth abdominal tergite divided in the middle, forming two lobes, the apices with 1 small hook on ventral surface, directing upwards and inwards (
Fig. 8
F). Cerci longer, cylindrical, the apical half slightly curved upwards (
