Description.

Measurement. ♂, BL: 12.0 mm; HL: 1.9 mm; HW: 1.4 mm; FWL: 8.5 mm.

Coloration. General color brown, marked with fuscous and ochraceous (Figs 51-53). Vertex dark scattered numerous yellowish spots, median carina ochraceous, lateral carinae and margin dark. Genae brown, eyes brown, ocellus yellowish, antenna dark and the areas surrounding ocellus and antenna beneath eye brown scattered yellowish spots. Frons pale brown with brown spots. Postclypeus, anteclypeus yellowish-brown and the apex black. Pronotum dark scattered brown spots, median carina brown, lateral carinae dark; lateral, ventrally curved areas brown. Mesonotum ochraceous scattered black brown spots. Thorax ventrally dark brown. Forewings with venation and stigma brown. Legs dark with pale brown spots.

Head and thorax. Head (Figs 23-25, 51-53) slightly short and robust, shorter than pronotum and mesonotum combined (0.67:1). Vertex (Figs 23, 51, 52) with conspicuous median carina; disc sunking distinct. Frons (Fig. 24) with lateral carinae reaching to the behind of eyes, not to frontoclypeal suture. Pronotum (Figs 23, 51, 52) with distinct median carina, lateral carinae curved. Mesonotum (Fig. 23) tricarinate on disc, lateral carinae curved towards median carinae at the front. Forewing (Figs 26, 51-53) longer than widest part (3.06:1), venations as in Fig. 26; hindwing longer than widest part (2.13:1), venations as in Fig. 27. Spinal formula of hind leg 8-11-11.

Male genitalia. Anal style (Figs 28, 29) short, broad. Anal tube (Figs 28, 29) large, nearly oval in lateral view; long, capitate in dorsal view, ratio of length to width at middle about 1.5:1. Pygofer (Figs 28-30) large and broad in lateral view, posterior margin with a blunt process dorsally. Parameres (Figs 29, 30) relatively long in ventral aspect. Aedeagus (Figs 31-33) with phallobasal conjunctival processes produced dorsally and ventrally, respectively; left one obviously longer than right one; phallobase narrow and long, curved dorsally; apicodorsal membranous lobe large in lateral view (Fig. 32), with two small processes, one covered with numerous fine spines, another not; apicoventral membranous lobe converging towards apex and rounded in ventral view (Fig. 31) with two stout spine-like processes, directed anteroventrally in lateral view, covered with numerous fine spines.

Type material.

Holotype: ♂, China: Yujun Mountain (N30°04', E101°57', 3,000 m), Kangding County, Sichuan Province, 6 Aug. 1999, G.-D. Ren. (IEGU).

Etymology.

This new species is named for its aedeagus having two stout spine-like processes apically.

Distribution.

China (Sichuan).

Remarks.

This species is similar to Saigona ussuriensis (Lethierry, 1878), but can be distinguished from the latter by its anal tube obviously narrowing at basal third; apicoventral lobe of pallobase with two stout processes at apex; phallobasal conjunctival processes asymmetrical apically.
