Telema breviseta , new species

( Figs. 1B , 3A–I , 6 )

Holotype. – Male ( IZCAS), Yalong Cave (18 ° 59'N 108 ° 53'E), Yalong Village, Donghe Town, Dongfang City, Hainan Island, China, coll. Y. Song, X. Han, G. Deng and Y. Tong, 1 Apr.2005.

Paratypes. – 8 females, 6 males ( IZCAS), same data as holotype ; 2 females, 1 male ( IZCAS), a cave (not named) (19 ° 01'N 109 ° 04'E), Nanlang village , Donghe town , Dongfang city, Hainan Island, China, same collectors as holotype, 30 Mar.2005 .

Diagnosis. – The new species is similar to T. nipponica ( Yaginuma, 1972) and can be distinguished by the presence of a small prolateral cymbial apophysis, the distinctive shape of papal bulb of males, the presence of a row of short setae on anteroventral surface of femur I, the shape of sternum, and the presence of two large promarginal teeth on fang furrow.

Description. – Males. Total length 0.98–1.09. Carapace 0.51– 0.53 long, 0.47–0.50 wide; abdomen 0.58–0.61 long, 0.44– 0.46 wide. Carapace yellowish brown with brownish margin; at center a dark suffused area from which ill-defined striae diverge; area before AM with two light yellow rings, indistinct in some specimens. Legs, labium, endites and chelicerae yellowish brown. Sternum dark brown. Abdomen gray, blackened on posterior area; spinnerets light yellow, colulus blackened. Carapace with pair of setae at clypeus, behind eyes, and at middle. Six eyes, anterior row of four eyes nearly straight, AM close together, nearly touching, separated from AL by 1/2 diameter of AL, lateral eyes contiguous. Promargin of fang furrow with two large tooth, and three small denticles, retromargin with four barely visible denticles. Legs with dorsal spine at distal end of patella as well as at middle of tibia. Leg measurements: I 2.90 (0.86, 0.18, 0.87, 0.56, 0.43); II 2.55 (0.77, 0.17, 0.74, 0.46, 0.41); III 1.93 (0.62, 0.17, 0.48, 0.34, 0.32); IV 2.44 (0.77, 0.17, 0.66, 0.47, 0.37). Leg formula: I-II-IV-III. Femur I with characteristic row of short setae on anteroventral surface (also present in femur II on specimens of Nanlang). Palp with prolateral slender cymbial apophysis; bulb oval with one simple apophysis.

Females. Total length 1.05–1.12. Carapace 0.51–0.58 long, 0.48–0.54 wide; abdomen 0.62–0.67 long, 0.47–0.51 wide. Eyes and chelicerae as in male. Leg measurements: I 2.84 (0.85, 0.18, 0.82, 0.52, 0.47); II 2.46 (0.76, 0.17, 0.69, 0.45, 0.39); III 1.88 (0.57, 0.17, 0.48, 0.34, 0.32); IV 2.41 (0.76, 0.17, 0.66, 0.45, 0.37). Leg formula: I-II-IV-III. Femur I without special setae. Epigynum with sparse hairs on epigynal plate, and another row behind epigastric furrow. Spermatheca strong, with distal end swollen and curved downwards.

Etymology. – The specific name is from Latin “ brevi = short, and seta = bristle”, and refers to the row of short setae on anteroventral surface of femur I.
