Description

MEASUREMENTS AND RATIOS. LT: ♂ (n = 5): 28.7 mm (27.2–30.0); ♀ (n = 1): 29.7 mm; LTg/BTg = 2.80; BV/LV = 4.57; LF/BF = 0.71.

HEAD. Pale yellow-brown ( Fig. 5 C–D); vertex strongly curved and deeply grooved with lowest point in middle and with all margins carinate ( Fig. 5C ); frons slightly visible from above ( Fig. 5C ), strongly convex, smooth, subquadrate with sides projecting laterally basally and with impressed C-shaped groove along lateral margin, starting in front of eye ( Fig. 5D ); clypeus subtriangular, narrower and shorter than frons, black-brown ( Fig. 5D ); labium elongate, black-brown, surpassing hind coxae ( Fig. 5B ); antennae pale yellow-brown with scape cylindrical, slightly elongate and pedicel strongly bulbous ( Fig. 5D, F ).

THORAX. ( Fig. 5C, F ). Dark brown to black-brown; pronotum irregularly wrinkled with smooth longitudinal carina and 2 strongly impressed points on anterior half of disc; mesonotum with disc wrinkled and sides smooth; scutellum impressed basally, elevated apically and slightly transversely winkled; tegulae brown with apex pale yellow-brown.

TEGMINA. ( Fig. 5 A–B, E). Dark brown to black-brown with olivaceous green hue on basal half, more conspicuous ventrally; veins and veinlets yellow-brown, maybe olivaceous green in living specimens; 3–4 small, yellow-white spots along costal margin, 2–4 along claval joint and 2 longitudinally aligned on disc near nodal line; costal and sutural margin subparallel; apex oblique with apico-sutural angle broadly rounded.

HIND WINGS. ( Fig. 5 A–B). Dark brown to black-brown with a basal milky-white elongate patch along costal vein; broader than tegmina.

LEGS. ( Fig. 5 A–B). Dark reddish brown to nearly black; anterior legs darker; tibiae I slightly foliaceous externally; tibiae II slender; tibiae III with 4–5 lateral and 7 apical spines.

ABDOMEN. ( Fig. 5 A–B). Tergites black with membranous joints greenish; sternites brown; genital segments black-brown.

MALE GENITALIA. Pygofer, anal tube and gonostyli black-brown; pygofer higher than long, with posterior margin sinuate in lateral view ( Fig. 10 A–B); anal tube elongate, 1.95 times longer than broad, broader at 3⁄5 of total length, strongly curved ventrally near base ( Fig. 10 A–B); lateral margins sinuate ( Fig. 10A ) and apical margin excavate in dorsal view ( Fig. 10C ); gonostyli ( Fig. 10A ) elongate with posterior half broader and strong subbasal constriction in lateral view; strong tooth directed antero-ventrally at half length; apical margin rounded; phallic complex ( Fig. 10 D–E) with endosomal process of aedeagus laminate, slightly concave externally and with ventral margin laterally projecting subbasally; dorsal margin rounded in lateral view and nearly smooth, showing few slightly marked teeth near base and near apex.

Distribution

Known from Peleng Island off Central Sulawesi (see map Fig. 7 ).
