Type material: Holotype: female, CHINA, Yunnan Province, Tengchong County, 41–46 km of the road Bawan to Tengchong, Dahaoping Village [N24.55625º, E99.45155º], 2416 m, 18 October 2003, Guo Tang leg (HNU-Tang 03101803). Paratypes, Baoshan City: 1 Ψ, Yakou of Nankang [N24.43717º, E98.46054º], 2186 m, 31 October 2003, Guo Tang (CAS-Tang 031031); 1 Ψ, Nankang [N24.294º, E98.282º], 2100 m, 4–7 November 1998, Charles Griswold (HNU-98NK37).
Etymology. The specific name is derived from the Latin curvatus, meaning curved and referring to the shape of the copulatory ducts, adjective.
Diagnosis. This species is similar to L. dentatus Tang, Yin, Peng, Ubick & Griswold, 2007 in general appearance, but can be separated from the latter by: opisthosoma dorsum with large blackish markings and some white bilateral spots (3 pairs of small black markings posteriorly in L. dentatus), copulatory ducts curved in S-shape (sinuous in L. dentatus). This species is also similar to L. bhutanus Ono, 2001 and L. saltus Ono, 1979 in markings style, but can be separated from those species by the long S-shaped copulatory ducts.
Description. Female: Total length 3.50. Prosoma 1.70 long, 1.40 wide; opisthosoma 2.00 long, 1.30 wide. Dorsal shield of prosoma light brown, with a pair of brown lateral stripes. Both anterior and posterior eye rows recurved. Eye tubercles blackish brown with white rim. ALE tubercles largest. Eye sizes and interdistances: AME 0.08, ALE 0.20, PME 0.05, PLE 0.15, AME-AME 0.20, AME-ALE 0.19, PME-PME 0.30, PME-PLE 0.32; MOA 0.45 long, front width 0.45, back width 0.48. Sternum yellow with black hairs. Chelicerae, gnathocoxae and labium yellow. Leg measurements: I: 5.20 (1.80, 1.80, 0.90, 0.70), II: 5.60 (1.90, 2.00, 1.00, 0.70), III: 3.40 (1.10, 1.10, 0.70, 0.50), IV: 4.20 (1.50, 1.50, 0.70, 0.50); formula 2, 1, 4, 3. Legs light yellow with many spines, tibiae with gray annular marking, femora I with 3 prolateral spines, tibiae and metatarsi I, II with 2 pairs of ventral spines, tibiae and metatarsi III, IV with 1 pair of ventral spines. Opisthosoma oval, dorsum yellow with pairs of medial white spots and a pair of longitudinal black bilateral stripes; venter yellow with a large rectangle black marking before spinnerets.
Epigyne-vulva (Figs 6 d–g). Atrium small, copulatory openings medial; copulatory ducts slender, curved in “S”-shape in ventral view; spermathecae ball-shaped.
Male: Unknown.
Variation. Total length: females 3.40–3.60 (n = 3). Femora I, II with 2 or 3 dorsal spines, markings on opisthosoma dorsum vary in size (Figs 6. a–c).
Distribution. China (recorded from Tengchong County and Baoshan City of Yunnan Province).
