(Fig. A. 5; B. 5, 11; C. 5; D. 5)

Type material. Holotype male, China: Guangxi, Fangfenggang, Shangsi, 10 Jul. 1991, coll. Wen Lu (SEM).

Diagnosis. Male. Bottom of rostrum truncated slightly inward. Epistomal suture slightly wide and distinctly curved upward. Distal edge of labrum narrow and straight. Lateral ocelli a little large, oval and flat. Occiput somewhat narrower than anterior pronotum. Pronotum slightly parallel-sided. Oblique veins four (three, on covered tegmen, and outermost vein apart from corner), the outermost vein normally close to the corner of stridulatory vein; second vein short and very distant from that corner. Inner side of mirror normally bent (strongly bending on covered tegmen). Crossvein between chord and mirror reaches to a little below the inside corner of mirror. Inner branches of Cu1 at apical field nine, the last vein being very short (eight on covered tegmen and fourth closing to fifth at base). Forewings distinctly reach well beyond the tip of abdomen. Stridulatory file, inside apex apart from hair, with only 58 anvil-like teeth. Hindwings long, obviously reaching beyond the tip of cercus. Genitalia: Median notch between paired lower apical teeth not reaching dorsal edge of epiphallic apex, above it with a lappet slightly inclined inward. Outer edge of paired lower apical teeth with an ear-like boss at median.

Coloration. Head and pronotum rufous. Most of hind femur brown. FWs light brown. Occiput uniform rufous. Bottom 1/3 of cheek brown. Frons with inconspicuous angular light patch. Crescent pattern of pronotum distinctly red. Bottom 1/3 part of lateral lobe with a distinct light stripe. Subapex of hind femur with brown dorsal patch.

Measurements. BL 25; HW 6.5; PL 5; PW 7.5; FWL 18.5; FWW 7.5; AFL 9.5; HWL 7.5; HLL 15.5; CL 7; API 1.27; PI 1.50; NST 58; SFL 4.43; DST 13.

Etymology. The specific epithet “ longus ” alludes to the longer FWs of the species which conspicuously reach well beyond the tip of the abdomen.
