Diagnosis.

Big-sized species with General color yellow, anal segment with a pair of spinose processes, forked apically (Figs 50-51); aedeagus with eight processes and with many irregularity ventral teeth at subapically (Fig. 52).

Description.

Coloration. Head yellow. Vertex yellowish white to black (Figs 39, 41). Frons black except middle carinae yellowish white and lateral margin yellowish brown (Figs 40, 42). Clypeus and genae yellow (Figs 40, 42). Rostrum yellowish brown, with apex brown. Eyes generally yellow to brown (Figs 35-42), ocelli yellowish brown (Figs 36, 38, 40, 42). Antennae yellow (Figs 35-42). Pronotum and mesonotum with carinae yellowish brown (Figs 39, 41). Forewings with veins dark brown (Figs 35-38). Hindwings pale white, veins brown. Legs yellowish white to pale yellowish; tibiae yellow basally, tarsomeres yellowish white (Figs 36, 38). Abdomen yellow (Figs 35-38).

Structure. Head including eyes narrower than pronotum, ratio 0.79:1 (Figs 39, 43). Vertex with anterior margin transverse, lateral carinae with slightly concave, longer than wide at base, ratio 1.22:1, narrower at apex than at base, ratio 0.55:1 (Figs 39, 43). Frons longer in middle line than wide at widest part, ratio 1.83:1, lateral carinae straight (Figs 40, 44). Postclypeus wider at base than frons at apex, slightly longer than wide at base (Figs 41, 46). Antennae cylindrical, basal segment longer than wide, ratio 1.55:1, shorter than second, ratio 0.38:1 (Figs 39-44). Pronotum shorter than vertex, ratio 0.67:1 (Figs 36, 38, 40, 42, 44). Mesonotum longer pronotum and vertex combined, ratio 1.21:1 (Figs 39, 43). Forewings longer than widest part, ratio 3.85:1, widest at apical 1/4 (Figs 35-38, 45). Posttibial spur with approximately 29-32 distinct teeth along hind margin.

Male genitalia. Anal segment with a pair of spinose processes, forked apically (Figs 50-51). Pygofer quadrate in caudal view (Figs 47-49). Diaphragm broad, transparent, dorsal margin arched (Fig. 49). Aedeagus with eight processes and with many irregularity ventral teeth at subapically (Fig. 52). Genital styles with lateral margins arched in caudal view, with two lateral margins almost parallel in profile (Figs 53-54). Suspensorium large and X-shaped, with a process at each lateral margin (Fig. 55).

Female genitalia. Gonocoxa VIII with base of inner margin slightly concave (Fig. 57). Gonapophyses VIII with apex sharp, ventral margin membranous at half of apical, in dorsal margins with several small teeth at half of apical (Fig. 58). Gonapophyses IX long, sclerotized, curved basally and narrowing towards apex, serrated caudad in distal, with approximately 18 teeth, abruptly reduced and indistinct at apex (Fig. 59). Gonoplacs twisted (Fig. 60).

Report hosts.

None.

Distribution.

China (Guizhou, Yunnan).

Etymology.

The specific epithet is from the Latin word furca (forked), indicating the anal segment produced lateroapical angles forked.

Remarks.

This species is similar to Parasogata binaria sp. n., but can be distinguished by the anal segment with a single pair of processes (two pairs of processes in Parasogata binaria sp. n.), suspensorium with dorsal margin hunch-up (with dorsal margin concave in Parasogata binaria sp. n.).
