Description.

Measurement. ♂, BL: 15.7 mm; HL: 2.4 mm; HW: 1.5 mm; FWL: 11.8 mm.

Coloration. General color brown, marked with fuscous and ochraceous (Figs 45-47). Vertex brown with median carina ochraceous, lateral margins brown. Genae brown, eyes brown, ocellus yellowish, antenna brown and the areas surrounding ocellus and antenna beneath eye yellowish. Frons yellowish. Postclypeus, anteclypeus black. Pronotum pale brown, lateral, ventrally curved areas with a yellowish band. Mesonotum pale brown scattered white spots and yellowish at the apex. Thorax ventrally at the fore femur brown, the other area pale green. Abdomen dorsally dark, with yellowish band on disc, ventrally dark. Forewings venation brown and stigma dark. Legs dark, tibiae with green rings. Genitalia black.

Head and thorax. Head (Figs 1, 45-47) shorter than pronotum and mesonotum combined (0.75:1). Vertex (Fig. 1) with median carina very faint, only conspicuous at apex and base; lateral carinate margins curved. Frons (Fig. 2) with lateral carinae almost reaching to to frontoclypeal suture. Mesonotum (Figs 1, 45-47) tricarinate on disc, lateral carinate curved towards media carinate at the front. Forewing (Figs 4, 45-47) longer than widest part (2.85:1), venation as in Fig. 4; hindwing longer than widest part (2.43:1), venation as in Fig. 5. Spinal formula of hind leg 8-12-11.

Male genitalia. Anal tube (Figs 6, 7) large, nearly triangular in lateral view (Fig. 41), large, long, round in dorsal view (Fig. 39), ratio of length to width at middle about 2:1. Pygofer (Fig. 7) large and broad in lateral view, posterior margin with a slightly sharp process dorsally. Parameres (Figs 7, 8) relatively large, broad in lateral aspect (Fig. 7), apex sharply rounded, protruded posteriorly. Aedeagus (Figs 9-11) with phallobasal conjunctival processes unequal in length, left one obviously longer than right one; phallobase narrow and long, curved dorsally; apical, dorsal, membranous lobe small in lateral view (Fig. 10), and long oval in dorsal view (Fig. 11); apical, ventral, membranous lobe converging towards apex and oval in ventral view (Fig. 9), directed anteroventrally in lateral view (Fig. 10), covered with numerous fine spines and veins.

Type material.

Holotype: ♂, China: Baiyun Mountain (N34°08', E112°05'), Henan Province, 13 Aug. 2008, X.-H. Hou. (IEGU).

Etymology.

This new species is named for its aedeagus with two phallobasal conjunctival processes unequal in length.

Distribution.

China (Henan).

Remarks.

This species is similar to Saigona henanensis Liang & Song, 2006, but can be distinguished from the latter by its phallobasal conjunctival processes not spiraled at apical 1/5, left one obviously longer than right one; phallobase with apical, dorsal small, with apical, ventral, membranous lobe small, not hook-like in lateral view.
