Redescription.

Body length: male: 5.5-5.9 mm (N = 2).

Coloration. General color blackish brown (Figs 1A, B , 3A, B ). Eyes brown, ocelli yellowish brown. Vertex brown, pronotum dark brown and mesonotum blackish brown. Frons generally yellowish brown, blackish brown above frontoclypeal suture. Clypeus blackish brown. Rostrum generally brown except darker tip. Forewing semi-translucent, with a small irregular blackish brown spot at branch of Y-vein, stigma blackish brown. Hind tibiae yellowish brown and abdominal sternites blackish brown.

Head and thorax. Vertex (Fig. 3A ) broad, 2.2 times wider than long; anterior margin arched convex, posterior margin arched concave; median carina reaching transverse carinae, indistinct. Frons (Fig. 3B ) 1.2 times as wide as long, median carina indistinct, extending from slightly above level of lateral ocelli to median ocellus. Clypeus with median carina distinct and elevated throughout. Pronotum (Fig. 3A ) 2.2 times longer than vertex, posterior margin nearly at right angle. Mesonotum 1.6 times longer than pronotum and vertex combined. Forewing (Fig. 3C ) 3.0 times longer than wide, with 10 apical and 6 subapical cells; fork Sc+RP distad of fork CuA1+CuA2; first crossvein r-m basad of fork MP; RP 2 branches, MP with five terminals: MP11, MP12, MP2, MP3, and MP4, fork MP1+MP2 basad of fork MP3+MP4. Hind tibia with 2-3 lateral spines, metatibiotarsal formula: 6/7/7-8, second segment of hind tarsus with 2-3 platellae.

Male genitalia. Pygofer (Fig. 3D, E ) symmetrical, dorsal margin concave and U-shaped ventrally, widened towards apex; in lateral view, lateral lobes arched extended caudally. Medioventral process triangular in ventral view. Anal segment (Fig. 3D, F ) long, tubular, symmetrical, apical lobes slightly enlarged, 2.2 times longer than wide in dorsal view; anal style finger-like, not extending beyond anal segment. Gonostyli (Fig. 3D, E, G ) symmetrical in ventral view; in inner lateral view, apical part extended, apical margin round. Aedeagus (Fig. 3H-K ) in total with three processes. Right apex of periandrium with a medium-sized spinose process, curved and apex directed left-ventrocephalad; spinose process on left side near apical 1/3 of periandrium being the longest, gently curved from left to right side over periandrium and apex directed to the right side; base of periandrium ventrally with one small tooth. Endosoma slender, structure simple, left side near the middle with a stout and short spinose process, apex directed dorsocephalad.

Host plant.

Unknown.

Distribution.

China (Guizhou), Russia (Sakhalin Island).

Remarks.

This species can be distinguished from other species of the genus by the following characters: anal segment symmetrical; aedeagus with three processes: right spinose process of periandrium curved and apex directed left-ventrocephalad; left spinose process of periandrium being the longest, curved over periandrium and apex exceeding right lateral margin of periandrium; spinose process of endosoma stout and short, apex directed dorsocephalad.

Note.

This species is recorded from China for the first time.
