Polydictya katsurakoae – Nagai & Porion 2002: 9 (record from Wowoni Island) [erroneous identification].

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.

Description

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

Known from Central, South and South East (Buton and Wowoni Islands) Sulawesi ( Fig. 7 ).
