Description.

Coloration. General color yellowish white to yellowish brown. Head yellowish brown (Figs 13-16). Vertex yellowish white, except along lateral margin dark brown (Figs 13-16). Frons black, except median carinae yellowish white and lateral margins yellowish brown (Fig. 14). Clypeus and genae yellowish brown (Fig. 14). Rostrum yellowish brown, with apex brown. Eyes generally yellow to brown (Figs 9-16), ocelli dark brown (Figs 10, 12, 14, 16). Antennae yellow (Figs 13-16). Pronotum and mesonotum yellowish brown, except media carinae yellowish white (Figs 13, 15). Forewings with veins dark brown (Figs 9-12). Hindwings pale white, with veins brown. Legs yellowish white to pale yellow, tibiae pale yellow basally, tarsomeres yellowish white (Figs 10, 12). Abdomen brown, except lateral margins yellow (Figs 9-12).

Structure. Head including eyes narrower than pronotum, ratio 0.77:1 (Figs 13, 15). Vertex with anterior margin arched, lateral carinae slightly concave, submedian carinae uniting at apex, longer than wide at base, ratio 1.28:1, narrower at apex than at base, ratio 0.64:1 (Figs 13, 17). Frons longer in middle line than wide at widest part, ratio 2.28:1 (Figs 14, 18), lateral carinae nearly straight (Figs 14, 18). Postclypeus wider at base than frons at apex, slightly longer than wide at base (Figs 14, 18). An tennae cylindrical, basal segment longer than wide, ratio 1.55:1, shorter than second, ratio 0.42:1 (Figs 14, 18). Pronotum shoter than vertex, ratio 0.75:1 (Figs 13, 17). Mesonotum longer than pronotum and vertex combined, ratio 1.25:1 (Figs 13, 17). Posttibial spur with approximately 30-32 distinct teeth along hind margin. Forewings longer than widest part, ratio 3.48:1, widest at apical 1/4 (Figs 10, 12, 19).

Male genitalia. Anal segment with two pairs of spinose processes, upper pair smaller (Figs 24-25). Pygofer quadrate in posterior view (Figs 21-23). Diaphragm broad, transparent (Fig. 23). Aedeagus with ten processes subapically and with irregularity teeth at ventral of apex, constriction and blunt rounded at apex (Fig. 26). Genital styles with inner margin arched and outer margin concave in caudal view, distinctly constricted at apex (Figs 27-28). Suspensorium large and arrow-shaped (Fig. 29).

Female genitalia. Gonocoxa VIII at base of inner margin arched (Fig. 31). Gonapophyses VIII with apex sharp, with ventral margin membranous at half of apex, dorsal aspect with several small teeth apically (Fig. 32). Gonapophyses IX long, sclerotized, curved basally, narrowing towards apex, with approximately 17 teeth, abruptly reduced and indistinct at apex (Fig. 33). Gonoplacs twisted, long and stripe-shaped (Fig. 34).

Report hosts.

None.

Distribution.

China (Yunnan).

Etymology.

The specific epithet is from the Latin word binaria (bipartite), referring to the anal segment with two pairs of processes.

Remarks.

The species is similar to Sogata dohertyi (Distent, 1906), but can be distinguished by anal segment with processes cross (not cross in Sogata dohertyi ), aedeagus with a row processes (without process in Sogata dohertyi ).
