Diagnosis. This species is similar to L. subdianicus sp. nov. (Figs 17 a–d) in general appearance and the genital organs: but differs in: the embolus being longer; the RTA short stick-shaped versus long spatulate in L. subdianicus; cymbium with modification absent in L. subdianicus; atrium almost as long as wide versus much wider than long in L. subdianicus; the copulatory ducts with fold absent in L. subdianicus. This species is also similar to L. silvanus Ono, 1980 and L. coronatus (Grube, 1861) in slender embolus, but can be separated from those species by: the RTA digitform (spatulate in L. silvanus), the copulatory ducts twist in 1 circle (about 2–3 circles in L. silvanus); the cymbium wider than in L. coronatus, VTA apically curved prolaterally (curved retrolaterally in L. coronatus).
Description. Male (HNU-CGY0512401, this is the first description of the male): Total length 3.70. Prosoma 1.60 long, 1.70 wide; opisthosoma 2.00 long, 1.50 wide. Dorsal shield of prosoma yellow, with sparse long setae, and with a pair of brown bilateral markings. Eye sizes and interdistances: AME 0.13, ALE 0.20, PME 0.06, PLE 0.15, AME - AME 0.20, AME - ALE 0.23, PME - PME 0.36, PME - PLE 0.38, MOA 0.40 long, front width 0.42, back width 0.45. Clypeus blackish brown. Both AER and PER strongly recurved. Sternum yellow. Chelicerae long, blackish brown, promargin with a row of curved thick hairs and 2 small teeth, retromargin with a row of curved hairs and 1 smaller tooth; gnathocoxae and labium long, light blackish brown. Legs I, II brown; III, IV yellow. Leg measurements: I: 7.60 (2.00, 3.00, 1.60, 1.00); II: 7.90 (2.20, 3.00, 1.60, 1.10); III: 4.60 (1.50, 1.60, 0.90, 0.60); IV: 5.10 (1.60, 1.80, 1.00, 0.70), formula: 2, 1, 4, 3. Opisthosoma nearly oval, dorsum anteriorly with a pair of brown longitudinal stripes; medially with a pair of white spots; posteriorly with 3 pairs of blackish brown stripes; sides with broken white spots and 5 black lines; venter gray with a U - shaped light black mark posteriorly.
Palp (Figs 7 c–f, i). VTA strongly sclerotized, apically curved, RTA with a basal projection, distal parts of RTA stick - shaped. The embolus slender and curved anticlockwise, large helix - shaped.
Female: (HNU-CGY0512401): Total length 4.00. Prosoma 1.70 long, 1.50 wide; opisthosoma 2.20 long, 2.00 wide. Body markings as in male. Clypeus brown, sternum light yellow. Chelicerae brown, gnathocoxae and labium brown. Leg yellow, leg measurements: I: 5.20 (1.50, 2.00, 1.00, 0.70); II: 5.60 (1.70, 2.00, 1.20, 0.70); III: 3.80 (1.20, 1.40, 0.70, 0.50); IV: 4.30 (1.40, 1.50, 0.90, 0.50), formula: 2, 1, 4, 3. Opisthosoma wider than in male.
Epigyne-vulva (Figs 7 g–h, j–k). Atrium large; copulatory ducts much wider anteriorly, twisted tubeshaped posteriorly; spermathecae globular.
Variation. Total length males: 3.00–3.90 (n = 31); females: 3.60–4.20. (n = 73). The markings of the opisthosoma dorsum vary in size and pigmentation.
Distribution. China (recorded from Yunnan Province: Gongshan, Fugong, Lushui, Longling, Tengchong Counties and Baoshan City).
