Tang leg.; 1♂ (IZCAS-Ar44501), Wuzhishan City, Wuzhishan National Nature Reserve, 7.viii.2007, C.X. Wang leg.

Etymology.

The specific name is after Prof. Liang Wei from Hainan Normal University, China; noun (name) in genitive case.

Diagnosis.

Gedea liangweii sp. nov. closely resembles that of G. daoxianensis Song & Gong, 1992 in having very similar habitus and copulatory organs, but it can be easily distinguished by the following: (1) the DTA bears six digitiform apophyses distally in retrolateral view (Fig. 3C ), vs. several long setae-like apophyses in G. daoxianensis ( Song and Gong 1992: fig. 6); (2) the copulatory openings are anteriorly located (Fig. 4A ), vs. posteriorly located in G. daoxianensis ( Song and Gong 1992: fig. 3); (3) the copulatory ducts are curved ~ 180° medially (Fig. 4B ), vs. curved ~ 100° in G. daoxianensis ( Song and Gong 1992: fig. 4).

Description.

Male (Figs 3 , 4C, D, F, G ). Total length 3.26. Carapace 1.72 long, 1.35 wide. Abdomen 1.57 long, 1.20 wide. Clypeus 0.07 high. Eye sizes and inter-distances: AME 0.37, ALE 0.26, PLE 0.21, AERW 1.24, PERW 1.11, EFL 0.80. Legs: I 3.48 (0.95, 0.65, 0.85, 0.63, 0.40), II 2.91 (0.90, 0.50, 0.63, 0.50, 0.38), III 3.33 (1.10, 0.50, 0.63, 0.70, 0.40), IV 3.23 (1.00, 0.43, 0.65, 0.75, 0.40). Carapace red-brown to dark brown, covered with dense yellow and white setae, with pair of indistinct, dark patches medially on eye field; fovea linear, longitudinal, dark. Chelicerae yellow, each with four promarginal teeth and one retromarginal fissidental tooth with four cusps. Endites paler than chelicerae, with sub-triangular distal processes extending laterally. Labium almost linguiform, bearing several dark setae at anterior margin. Sternum slightly longer than wide, with straight anterior margin, covered with paler thin setae. Legs yellow to brown, spinous. Abdomen elongate-oval, dorsum with two pairs of muscle depressions anteromedially and alternate dark brown and pale yellow transverse bands; venter pale-yellow to grey. Palp (Fig. 3A-C ). Tibia wider than long, with curved, tapered RTA coiled into a circle distally in retrolateral view, and platelike DTA bearing six digitiform apophyses at distal end; cymbium almost two times longer than wide; bulb swollen, with well-developed posterior lobe extending downward; embolus strongly sclerotized, tapered, and curved, originates from antero-prolateral portion of bulb, with rather pointed tip.

Female (Fig. 4A, B, E ). Total length 3.73. Carapace 1.59 long, 1.22 wide. Abdomen 1.91 long, 1.35 wide. Clypeus 0.08 high. Eye sizes and inter-distances: AME 0.35, ALE 0.23, PLE 0.20, AERW 1.12, PERW 1.02, EFL 0.73. Legs: I 2.53 (0.78, 0.50, 0.55, 0.40, 0.30), II 2.43 (0.75, 0.48, 0.50, 0.40, 0.30), III 3.04 (1.00, 0.50, 0.58, 0.63, 0.33), IV 2.99 (0.90, 0.43, 0.65, 0.68, 0.33). Habitus (Fig. 4E ) similar to that of male except darker, and with a more slender body. Epigyne (Fig. 4A, B ). Wider than long, with pair of small, posterolateral hoods; copulatory openings anteriorly located, almost round, separated from each other ca. their diameter; copulatory ducts thick, strongly curved ~ 180° medially; spermathecae almost elliptical, separated from each other more than their width; fertilization ducts originate from the inner of anterior portions of spermathecae, extending almost transversely.

Distribution.

Known only from the type locality in Hainan Province.
