Description. Male. Pronotal disc greenish-blue. Post-ocular stripe, stripe of the lateral lobes of the pronotum, tegmina, wings and dorsal portion of the thoracic and abdominal tergites black; face, lower half of the lateral lobes of the pronotum and thoracic and abdominal tergites yellowish white; legs light brown with a basal, black line in the lower margin of the hind femora ( Figs. 24A,B). Tegmina with a very small, yellowish-white subapical spot. ( Fig. 24C). Head moderately elongated, eyes globose and prominent, but not flaring towards the sides very much; frontal costa rounded in side view, in frontal view moderately divergent. Dorsal carina short, not reaching the fastigium; scutellum moderately expanded, rectangular ( Fig. 24B). Pronotum flat, low tectate, extending beyond the tip of the hind femora; mid line extending a little beyond the half lf the mid-pronotal disc; anterior spine stout, apically arcuate, ascendant to anterior edge ( Fig. 24D); lateral lobes of the pronotum wider than long; lateral shoulder carinae rounded and slightly prolonged ( Fig. 24C). Tegmina ovoid, covering the first abdominal tergite and with a small subapical spot ( Fig. 24C). Legs slender and elongate, fore femora with a little developed sulcation above; no apical spine; mid femora with a well-developed internal dorso apical spine; hind femora with a moderately developed pre-genicular spine. Abdomen. Subgenital plate longer than wide, ( Figs. 24 E–G), a little upturned, almost subacute, penultimate sternite with no medial prolongation ( Fig. 24F), cylindrical cerci of similar thickness throughout and rounded tip ( Fig. 24G); epiproct triangular with a pointed tip ( Fig. 24E).
