Lysiteles leptosiphus sp. nov.

Figs 26–27

Type material: Holotype: ♀, China : Hainan: above the Wuzhishan mountainside (N18º53.835', E109º41.889', alt. 1593 m), 9 April 2009, G. Tang ( IZCAS, Tang _ No. 111) . Paratype: 1 ♀, same data as holotype ( IZCAS, Tang _ No. 111) .

Etymology. The specific epithet is taken from the Latin adjective leptosiphus , and means small-tubeshaped, referring to the small copulatory ducts.

Diagnosis. This new species is similar to L. silvanus Ono, 1980 , but can be separated from the latter by the simple twist of the copulatory ducts around spermathecae (twisted together complicately in L. silvanus ).

Description. Female (holotype measured): Total length 2.80. Prosoma 1.10 long, 0.90 wide; Opisthosoma 1.80 long, 1.60 wide. Prosoma yellow, carapace with a large “n”-shaped blackish brown marking. Eye measurements: AME 0.07; ALE 0.12; PME 0.05; PLE 0.10; AME–AME 0.12; AME–ALE 0.22; PME–PME 0.20; PME–PLE 0.26. MOA length 0.26 with front width 0.28 and back width 0.30. Chelicera blackish brown, gnathecoxa and labium brown, sternum yellow. Legs yellow with sparse spines. Leg formula: II, I, IV, III; leg measurements: I: 2.70 (0.80, 1.00, 0.50, 0.40); II: 2.90 (0.85, 1.10, 0.55, 0.40); III: 2.05 (0.70, 0.75, 0.30, 0.30); IV: 2.15 (0.70, 0.80, 0.35, 0.30). Opithosoma with a pairs of longitudinal grayish black stripes extend to the venter.

Epigynum ( Figs 26 B–F, 27 A–B). Epigynum with a narrow sclerotized plate, copulatory openings bilaterally, copulatory ducts slender, twisted once around the oval spermathecae.

Male: Unknown.

Distribution. China (Hainan). Only known from the type locality.

Variation. Total length: female, 3.30–4.00 (n=2).
