Diagnosis. This species is similar to L. maius Ono, 1979 ( Figs 12 a–l ), the differences are discussed in the diagnosis of L. maius .

Description. Male: Total length 2.40. Prosoma 1.20 long, 1.00 wide; opisthosoma 1.30 long, 1.00 wide. Dorsal shield of prosoma blackish brown with an anchor-shaped black marking. Eyes with white rim. ALE>PLE>AME>PME. Chelicerae, labium, gnathocoxae blackish brown. Sternum black. Legs yellow with black annuli, and with weak spines. Femora with 3 prolateral spines, femora I–IV with 4 dorsal spines, tibiae and metatarsi I, II both with 2 pairs of ventral spines. Leg measurements: I: 4.40 (1.40, 1.30, 0.90, 0.80), II: 4.80 (1.50, 1.40, 1.00, 0.90), III: 3.20 (1.00, 1.00, 0.70, 0.50), IV: 3.50 (1.10, 1.00, 0.80, 0.60), formula: 2, 1, 4, 3. Opisthosoma ellipsoid, widest medially; dorsum brown, with many small black markings; laterally with some white spots; venter grayish black.

Palp ( Figs 13 e–g, j ). VTA stout and apically curved dorsally, RTA strongly sclerotized, spatula-shaped; bulb flat, sperm duct thick; embolus twisted and apically pointed.

Female: Total length 3.00. Prosoma 1.30 long, 1.20 wide; opisthosoma 1.70 long, 1.40 wide. Dorsal shield of prosoma blackish brown with a median black line. Leg measurements: I: 3.00 (1.00, 0.80, 0.70, 0.50), II: 3.30 (1.10, 0.90, 0.80, 0.50), III: 2.30 (0.70, 0.60, 0.60, 0.40), IV: 2.60 (0.80, 0.70, 0.60, 0.50), formula: 2, 1, 4, 3. Opisthosoma ovoid, widest medially, dorsum uniformly dark or with paramedian dark blotches; laterally with white spots; venter with black and white markings.

Epigyne-vulva ( Figs 13 h–i , l–k). Epigyne surrounded by black markings, sclerotized plate small; copulatory openings lateral; copulatory ducts short; spermathecae pyriform.

Variation. Total length: males 2.20–2.60 (n = 12); females 2.80–3.20 (n = 59). This species has variable opisthosoma markings ( Figs 13 a–d ), however, the shape and structure of the genital organs are diagnostic.

Distribution. Nepal, Bhutan; China (new to China, recorded from three counties: Tengchong, Gongshan and Longling of Yunnan Province).

FIGURE 23. Distribution records of the species: L. himalayensis Ono, 1979, L. kunmingensis Song & Zhao, 1994, L. maius Ono, 1979, L. niger Ono, 1979, L. punctiger Ono, 2001, L. saltus Ono, 1979, L. torsivus Zhang, Zhu & Tso, 2006. Not all of distribution data are given for those species with many distribution records because these would overlap on the map. Furthermore, only approximate distribution marks are given for the species published by others scholars (e. g., L. himalayensis distribution record from Bhutan and Nepal, etc.) because the original paper did not include latitude and longitude.
