Tong, Yanfeng & Li, Shuqiang, 2008, Four new cave-dwelling species of Telema (Arachnida, Araneae, Telemidae) from Guizhou Province, China, Zoosystema 30 (2), pp. 361-370 : 369

Telema oculata n. sp.

( Figs 1D ; 5 )

TYPE MATERIAL. — Holotype: China, Guizhou Province, Duyun City, Dushan County, Xiasi Town (25°29’N, 107°27’E), Guo-Jia-Fen-Dong Cave, 24.V.2005, Leg. Y. F. Tong & Y. C. Lin, ♀ ( MNHN).

Paratypes: same data as holotype, 3 ♀♀ ( IZCAS), 2 ♀♀ ( MNHN) ; same locality and collector as holotype, Liang-Shui-Jing-Dong Cave, 21.V.2005, 3♀♀ ( IZCAS), 2 ♀♀ ( MNHN) .

ETYMOLOGY. — The specific name is from Latin oculata, with eyes and refers to the presence of eyes in this species, for all recorded telema species from Guizhou are eyeless.

DIAGNOSIS. — The new species is closely similar to the female of T. nipponica ( Yaginuma, 1972) , distributed in Japan. However, in T. nipponica the sternum is triangular, and obtusely inserted into coxae IV, but this new species with a smoothly outer margin. This new species also has relatively longer legs (the shortest leg of the new species is nearly as long as the longest leg of T. nipponica ), the body size is larger, and the spermatheca is symmetrical in the new species (the spermatheca of T. nipponica is without figure, but described as asymmetrical thick curved tube [ Yaginuma 1973]).

DESCRIPTION

Female (n = 11)

Total length 1.40-1.45 (average: 1.42). Carapace 0.57-0.61 (average: 0.59) long, 0.51-0.53 (average: 0.52) wide; abdomen 0.79-0.83 (average: 0.81) long, 0.71-0.73 (average: 0.72) wide. Carapace, legs, labium, endites and chelicerae yellow.Sternum ( Fig. 5A ) deep brown. Carapace ( Fig. 1D ) nearly round, with pair of setae on the 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 one large tooth, one relatively small tooth and three barely visible granulous denticles, retromargin with four barely visible denticles ( Fig. 5F ). Legs with a dorsal spine at the distal end of patella as well as in the middle of tibia. Leg measurements: I 3.57 (1.12, 0.19, 1.10, 0.68, 0.48); II 3.12 (0.97, 0.18, 0.91, 0.58, 0.48); III 2.28 (0.72, 0.17, 0.60, 0.41, 0.38); IV 2.85 (0.92, 0.17, 0.81, 0.54, 0.41). Leg formula: I-II-IV-III.Abdomen globular, bluish-gray, the ventral surface being purplish-brown; colulus as in Figure 5D . Genital area with one row of hairs on epigynal plate, and another row behind epigastric furrow ( Fig. 5E ). Spermatheca distal end swollen, curved downwards ( Fig. 5B, C ).
