Diagnosis

(1) Tegmina brown, tinged with reddish ventrally on basal half (Fig. 2B), and with whitish markings: irregular one at apical half of clavus, 3 along claval suture, 4–5 along costal margin and 3–4 on disc of membrane (Fig. 2A); (2) hind wings with a large basal bright red patch (Fig. 2A); (3) frons regularly rounded in dorsal view, not projecting anteriorly (Fig. 2C), yellow-brown (Fig. 2D); (4) anterior tibiae not laminate (Fig. 2 A–B); (5) abdomen red dorsally (Fig. 2A); (6) genital segments red.

Etymology

The species epithet is formed by the words basis, -is (Latin) = base, and ruber, -bra, -brum (adj., Latin) = red, and refers to the bright red patch at the base of the posterior wing.

MEASUREMENTS AND RATIOS. LT: ♂ (n = 3): 26.7 mm (25.5–28.3); ♀ (n = 2, extrapolated): 30.0– 31.1 mm; LTg/BTg = 2.61; BV/LV = 6.13; LF/BF = 0.75.

HEAD. Yellow-brown with clypeus dark brown to black-brown with paler median line (Fig. 2 C–D, F); vertex curved with all margins carinate, and deeply grooved with lowest point in middle (Fig. 2C); frons slightly visible from above (Fig. 2C), convex, smooth, subquadrate, with impressed S-shaped longitudinal groove along lateral margin, starting in front of eye (Fig. 2D); clypeus narrower and shorter than frons (Fig. 2D); labium elongate, dark brown, surpassing hind coxae (Fig. 2B); antennae yellowbrown with scape cylindrical, elongate, and pedicel bulbous (Fig. 2D, F).

THORAX. (Fig. 2C, F). Dark brown with pronotum and sometimes disc of mesonotum paler yellowbrown; pronotum coriaceous with smooth median carina and 2 impressed points on anterior half of disc; mesonotum smooth with disc irregularly wrinkled and transverse wrinkles on scutellum; apex of scutellum elevated; tegulae dark brown with apex pale yellow-white.

TEGMINA. (Fig. 2 A–B, E). Brown with red hue on corium, more conspicuous ventrally; 4 subquadrate to rectangular pale yellow spots along costal margin; irregular yellow-white markings on disc along claval

joint and on clavus, and 2 spots on disc aligned longitudinally near nodal line; largest spot usually at apex of clavus; tegmina slightly broadening from base to apex and with apex oblique.

HIND WINGS. (Fig. 2 A–B). Brown with antero-basal bright red patch covering about ¼ of total surface and not reaching posterior margin; broader than tegmina.

LEGS. (Fig. 2 A–B). All legs reddish-brown; tibiae I and II slender; tibiae III with (4–)5 lateral and 7 apical spines.

ABDOMEN. (Fig. 2 A–B). Bright red with 2 basal tergites black; black ventrally; genital segments bright red.

MALE GENITALIA. Pygofer, anal tube and gonostyli bright red; pygofer higher than long, with posterior margin sinuate in lateral view and showing digitiform process in middle (Fig. 9 A–B); anal tube elongate, 2.26 times longer than broad, broader at half of total length, strongly curved ventrally near base (Fig. 9 A–B); lateral margins sinuate (Fig. 9B) and apical margin strongly notched in dorsal view (Fig. 9C); gonostyli (Fig. 9A) elongate with posterior half much broader and strong subbasal constriction in lateral view; strong tooth directed antero-ventrally at half length; apical margin broadly rounded; phallic complex (Fig. 9 D–E) with endosomal process of aedeagus laminate, slightly concave externally and with ventral margin laterally projecting subapically, showing irregular dorsal teeth along body and with apex pointed postero-ventrally.

Distribution
