Type material. Holotype: male, CHINA, Yunnan Province, Tengchong County, Xinhua Township, Longjing Village [N24.48203°, E98.23390°], 1940 m, 5 June 2006, Chang-Min Yin, Jia-Fang Hu and Xiao- Hua Yang (HNU-YHY2904).
Paratypes: 1 Ψ, same data as holotype (HNU-YHY2904); 1 Ψ, same Village as holotype, Shanqing [N25.48243°, E98.31454°], 1880 m, 27 May 2006, Chang-Min Yin, Jia-Fang Hu and Xiao-Hua Yang (CAS- YHY1305).
Etymology. The specific name is the combination of the Latin uni (meaning single) and processus (meaning apophysis), referring to the male palp only with one tibial apophysis (RTA), noun.
Diagnosis. This female can be separated from L. punctiger Ono, 2001 by: abdominal dorsum with 2 longitudinal black stripes versus some small black spots in L. punctiger ; the copulatory ducts visible versus invisible in L. punctiger . This male can be separated from the allied species by: palp only with RTA and the long filamentous embolus.
Description. Male (holotype): Total length 2.58. Prosoma 1.22 long, 1.06 wide; opisthosoma 1.40 long, 1.00 wide. Dorsal shield of prosoma blackish brown. Eye tubercles black, eye sizes and interdistances: ALE 0.14, PLE 0.10, AME 0.08, PME 0.06; AME-AME 0.12, AME-ALE 0.16, PME-PME 0.17, PME-PLE 0.21, MOA 0.23 long with front width 0.27, back width 0.30. Sternum light black. Chelicerae, gnathocoxae, labium black brown. Legs yellow except femur I blackish brown. Leg measurements: I: 3.50 (1.10, 1.20, 0.70, 0.50), II: 4.05 (1.25, 1.40, 0.80, 0.60), III: 2.10 (0.60, 0.70, 0.40, 0.40), IV: 2.60 (0.70, 0.90, 0.50, 0.40); formula 2, 1, 4, 3. Legs with many spines, including femora I with 3 prolateral spines, femora I–IV with 4 dorsal spines, tibiae I, II with 2 pairs of ventral spines and 2 prolateral, retrolateral and dorsal spines; tibiae III, IV with 1 pair of ventral spines. Opisthosoma dorsum blackish brown with some small brown dots; medially with longitudinal white stripes; laterally with brown lines; venter grayish white.
Palp ( Figs 20 d–f, h View FIGURES 20 a – j ). Palp with a long black RTA only, needle-shaped; bulb flat, embolus long, filamentous, apically curved.
Female (one of the paratypes, HNU-YHY2904): Total length 3.40. Prosoma 1.30 long, 1.12 wide; opisthosoma 2.07 long, 1.82 wide. Dorsal shield of prosoma yellow, eye tubercles grayish white. ALE 0.15, PLE 0.11, AME 0.09, PME 0.06, AME-AME 0.13, AME-ALE 0.19, PME-PME 0.26, PME-PLE 0.25; MOA 0.18 long, front width 0.33, back width 0.36. Sternum, chelicerae, gnathocoxae, labium yellow. Legs yellow with many spines, spination same as in male. Leg measurements: I 3.20 (1.00, 1.10, 0.60, 0.50), II 3.70 (1.20, 1.20, 0.70, 0.60), III 2.20 (0.70, 0.80, 0.30, 0.40), IV 2.50 (0.80, 0.90, 0.40, 0.40); formula 2, 1, 4, 3. Opisthosoma grayish yellow with black lateral stripes; medially with scaled white spots; venter grayish white.
Epigyne-vulva ( Figs 20 g, i–j View FIGURES 20 a – j ). Copulatory openings medial; copulatory ducts small, tube like, visible in ventral view; spermathecae spherical.
Variation. Total length: females 2.30–3.40 (n = 2). The sexual dimorphism is obvious between female and male although the marking styles are the same ( Figs 20. a–c View FIGURES 20 a – j ).
Distribution. China (recorded from Tengchong County of Yunnan Province).
