Measurements (mm) . Body (head to end of abdomen): ♂ , 3.0–3.6; ♀ , 3.7–4.9; length of pronotum: ♂ , 0.6–0.8; ♀ , 0.7–1.0; length of forewing: ♂ , 0.6–0.9; ♀ , 0.7–1.0; length of hind femur: ♂ , 1.7–2.0; ♀ , 1.8–2.3. Description . Male ( holotype ) . ( Fig. 5 ). Coloration in life ( Fig. 4 ): Head mostly creamy, with dark brown base and two dark spurs extending towards antennal bases; two brown marks between antennal bases; antennae creamy with tan apices; eyes black. Pronotum creamy overall; dorsum with large dark brown spot, symmetrical and becoming rounded on lateral lobes; posterior edge of spot poorly defined. Forelegs creamy, darkening to tan on tibiae; middle legs creamy, with dark markings on femora and tibiae, and elliptical white mass in tibiae; hind femora creamy, with two irregular brown transverse bands; apical crescents of hind femora light brown; hind tibiae creamy. Tegmina dark brown, anal area and apices white. Abdomen dark brown, tergites with irregular dark brown median spots; basal segment of cercus dark brown, apical segment cream; paraproctal processes white. Antennae 10-segmented. Forewings about as long as pronotum; hind wings absent. Male stridulatory file ( Fig. 6C ) 0.33 mm in length, with about 38 teeth. Swimming plates of hind tibia absent. Male epiproct ( Fig. 6A ) about as wide as long; very shallowly indented basally, convex apically, with long apical bristle about ¾ its length. Paraproct hooks strongly sclerotized, rounded apically and widened at middle. Male subgenital plate ( Fig. 5C ) truncated. Female subgenital plate ( Fig. 5D ) tapered apically, pinched laterally and rounded at apex.
