Description
ɗ, BL: 14.7 mm; HL: 4.0 mm; HW: 1.4 mm; FWL: 9.2 mm. Ψ, BL: 14.8 mm; HL: 4.3 mm; HW: 1.5 mm; FWL: 10.0 mm.
General color brown, marked with fuscous and ochraceous. Vertex and most part of genae brown, the areas surrounding ocellus and antenna beneath eye yellowish or yellowish green. Frons, postclypeus, anteclypeus, and rostrum yellowish or yellowish green. Pronotum ochraceous, suffused with fuscous; median carina pale green; lateral, ventrally curved areas yellowish. Mesonotum ochraceous, with broad, pale green stripe along median longitudinal carina. Thorax and abdomen ventrally yellowish or yellowish green; abdomen dorsally dark brown, with yellowish brown spots; pygofer and parameres fuscous, suffused with pale brown; anal tube yellowish dorsally. Legs yellowish brown, marked with ochraceous.
Head (Figs. 7, 8, 56–58) long, much longer than pronotum and mesonotum combined. Vertex (Figs. 7, 8, 56) with cephalic process long, distinctly robust; median carina very faint, only conspicuous at apex and base; lateral carinate margins nearly parallel. Frons (Fig. 58) with lateral carinae reaching to eyes, not to frontoclypeal suture.
Mesonotum (Figs. 7, 8, 56) with lateral carinae distinct, median carina very faint. Fore wing venation as in Fig. 62.
Male genitalia with pygofer (Figs. 59–61) large and broad in lateral view (Fig. 60), posterior margin nearly straight, abruptly curved anteriorly near 1/6 apex to accommodate anal tube, length ratio of upper margin to lower margin about 1: 2.2. Anal tube (Figs. 59, 60) large, nearly triangular in lateral view (Fig. 60), large, long, oval in dorsal view (Fig. 59), ratio of length to width at middle about 1.7: 1. Anal style (Figs. 59, 60) short, broad. Parameres (Figs. 60, 61) relatively large, broad in lateral aspect (Fig. 60), apex sharply rounded, protruded posteriorly. Aedeagus (Figs. 63–65) with phallobasal conjunctival processes produced dorsally and ventrally, respectively; phallobase narrow and long, curved dorsally; apical, dorsal, membranous lobe small, semi-globose in lateral view (Fig. 64), without spines; apical, ventral, membranous lobe converging towards apex and triangular in ventral view (Fig. 63), directed anteroventrally in lateral view (Fig. 60), covered with numerous fine spines at apex.
