Paralectotype: CHINA: Sichuan: [Fubyankho River, Between Shigaits and Shintyan], 0 1 Aug 1893, Potanin, 1Ƥ ( AMNH _PBI 00159817) ( ZISP). Other Specimens Examined: CHINA: Sichuan: Jinchuan, 2000–2350 m, 31.46666 ° N 102.05 ° E, 0 9 Sep 1963, Unknown, 13 ( AMNH _PBI 00337423) ( NKMU). Xiaojin, 30.98333 ° N 102.35 ° E, 2350 m, 26 Aug 1963, Le-Yi Zheng, 1Ƥ ( AMNH _PBI 00337424) ( NKMU).

Diagnosis. Recognized by the large size, 4.0–4.5 male, 3.9–4.9 female, comparatively small eyes in male with vertex 1.7–1.8 times as wide as eye, pale dorsum and tibial spines ( Fig. 1 ), darkened base of hind tibia, reduced color pattern on ventral surface of hind tibia ( Fig. 6 ), robust vesica 1.5–2.0 times as large as those in other species of the genus, membranous lobe around secondary gonopore prominent, covered with denticles arranged in 6–7 rows, small blade of vesica gradually tapering, attenuated laterally, with gradually curved base and straight apex, large blade somewhat sinuous and flattened, widened at middle ( Fig. 12 ). Not easily confused with other species of the genus. Most similar to L. xizangensis in the large size, uniformly pale dorsum, hind femur with reduced dark pattern on ventral surface and pale tibial spines but differing from that species in the darkened bases of hind tibia and tibial spines, and distinctive shape of vesica.

Distribution. Sichuan province of China.

Host. Unknown.
