(Fig. A. 4; B. 4, 10; C. 4; D. 4)

Type material. Holotype male, China: Yunnan, Xishuangbanna, Menghai, 2 Aug. 2000, coll. Zhe Li (HBU).

Diagnosis. Male. Frons normal. Epistomal suture wide and almost straight. Distal edge of labrum slightly concave. Lateral ocelli rounded and slightly convex. Occiput somewhat narrower than anterior pronotum. Pronotum slightly narrowed in front. Oblique veins three, the outermost vein apart from the corner of stridulatory vein. The inner side of mirror strongly bent (same on covered tegmen). The crossvein between the chord and mirror arrives at the inside corner of mirror. Inner branches of Cu1 at apical field eight (seven on covered tegmen). Forewings do not reach the tip of abdomen. Stridulatory file, inside apex distant from hairs, with 55 anvil-like teeth and four angular ones inside. Hindwings short, slightly overreaching the end of abdomen. Genitalia: Median notch between paired lower apical teeth not reaching dorsal edge of epiphallic apex, above it with a lappet; epiphallus very short and distinctly raised dorsally.

Coloration. Head and pronotum rufous. The apical half of hind femur brown, remainder yellow brown. FWs light brown. Occiput rufous with inconspicuous wide black stripe. Cheek with bottom 1/3 brown. Frons with a yellow strip across the median ocellus, and an angular yellow patch under the stripe, between them a pair of brown spots. Crescent pattern of pronotum distinctly red. Bottom 1/3 part of lateral lobe with a light stripe which is distinct in front. The subapex of hind femur without any dorsal patch.

Measurements. BL 27.5; HW 6.5; PL 5; PW 8; FWL 17.5; FWW 8.5; AFL 8.5; HWL 2; HLL 16; CL 8.5; API 1.06; PI 1.60; NST 59; SFL 4.29; DST 13.

Etymology. The specific epithet “ striatus ” refers to the yellow stripe across the median ocellus on the frons in this species.
