Description.
Body length: male 5.4-6.2 mm (N = 16), female 6.1-6.8 mm (N = 22).
Coloration. General color blackish brown (Figs 2C, D View Figure 2 , 6A, B View Figure 6 ). Eyes brown, ocelli yellow. Vertex brown, pronotum brown and mesonotum blackish brown. Frons generally brown and clypeus blackish brown. Rostrum generally brown except darker tip. Forewing semi-translucent, with a very small irregular blackish brown spot at branch of Y-vein, stigma dark brown. Hind tibiae brown and abdominal sternites blackish brown.
Head and thorax. Vertex (Fig. 6A View Figure 6 ) broad, 3.0 times wider than long; anterior margin slightly arched convex, posterior margin arched concave; median carina reaching transverse carinae. Frons (Fig. 6B View Figure 6 ) 1.2 times as wide as long, median carina indistinct, extending from basal 1/4 to median ocellus. Clypeus with median carina distinct and elevated throughout. Pronotum (Fig. 6A View Figure 6 ) 2.8 times longer than vertex, posterior margin nearly at right angle. Mesonotum 1.6 times longer than pronotum and vertex combined. Forewing (Fig. 6C View Figure 6 ) 3.0 times longer than wide, with 11 apical and 6 subapical cells; fork Sc+RP distad of fork CuA1+CuA2; first crossvein r-m basad of fork MP; RP 3 branches, MP with five terminals: MP11, MP12, MP2, MP3, and MP4, fork MP1+MP2 basad of fork MP3+MP4. Hind tibia with 3-4 lateral spines, metatibiotarsal formula: 6/7/8, second segment of hind tarsus with 2-4 platellae.
Male genitalia. Pygofer (Fig. 6D, E View Figure 6 ) symmetrical, dorsal margin concave and U-shaped ventrally, slightly widened towards apex; in lateral view, lateral lobes arched extended caudally. Medioventral process triangular in ventral view. Anal segment (Fig. 6D, F View Figure 6 ) long, tubular, nearly symmetrical, apical lobes slightly enlarged, 2.4 times longer than wide in dorsal view; anal style finger-like, not extending beyond anal segment. Gonostyli (Fig. 6D, E, G View Figure 6 ) symmetrical in ventral view; in inner lateral view, apical part extended, apical margin round. Aedeagus (Fig. 6H-K View Figure 6 ) in total with three processes. Spinose process on right side at apex of periandrium being the longest, gently curved from right to left side over periandrium, apex strongly recurved at 90° and directed apically; left side near base with a straight long spinose process, apex directed ventrocephalad; base of periandrium ventrally with several very small teeth. Endosoma slender, structure simple, left side near the middle with a stout and short spinose process, nearly straight, apex directed dorsocephalad.
Female genitalia. Tergite IX (Fig. 7A, B, D View Figure 7 ) moderately sclerotized, with a large wax plate, nearly oval, dorsal and ventral margins concave. Anal segment (Fig. 7C View Figure 7 ) rectangular, 2.1 times wider than long in dorsal view, anal style strap-like. Gonapophysis VIII (Fig. 7E View Figure 7 ) elongate, and slightly curved upwards. Gonapophysis IX (Fig. 7F View Figure 7 ) with two middle teeth, distance ratio between distal middle tooth to apex and length of denticulate portion is 2.6. Gonoplac (Fig. 7G View Figure 7 ) rod-like, 4.6 times longer than wide in lateral view. Posterior vagina pattern as shown in Figure 7H, I View Figure 7 .
Host plant.
Unknown.
Distribution.
China (Guizhou, Sichuan).
Note.
The female genitalia of this species are described and illustrated for the first time.
Remarks.
This species can be distinguished from other species of the genus by the following characters: anal segment symmetrical; right spinose process of periandrium being the longest, S-shaped, curved over periandrium and apex exceeding left lateral margin of periandrium; left spinose process of periandrium straight, apex directed ventrocephalad; spinose process of endosoma stout and short straight, apex directed dorsocephalad.
