New species of the spider genus Telema (Araneae, Telemidae) from caves in Guangxi, China Author Wang, Chunxia Author Li, Shuqiang text Zootaxa 2010 2632 1 45 journal article 10.5281/zenodo.276109 71a6e5ce-0c1a-49c9-9cb1-29c0839cda0b 1175-5326 276109 Telema cordata sp. nov. Figs 11–15 , 38 Type material: Holotype : male ( IZCAS ), Yiling Cave [ 23º02.374'N , 108º17.529'E , ALT: 151m , T: 23°C, H: 86%], Wuming County, Nanning, Guangxi, China , July 31, 2009 , C. Wang & Z. Yao leg. Paratypes : 20 males , 84 females , same data as holotype . Etymology: The specific name is derived from the Latin word “cordis”, meaning “heart”, and refers to the heart-shaped male palpal bulb; adjective. Diagnosis: This new species is similar to T. strentarsi Lin & Li, 2010 , but can be distinguished by the presence of six eyes ( Figs 12 A, 13A), the distinctly long, beak-shaped embolus ( Figs 11 A–B, 14A–B), and the semicircular spermatheca of female ( Figs 13 C, 15A). Description: male ( holotype ). Total length 1.70 ( Fig. 12 A). Prosoma 0.62 long, 0.60 wide. Opisthosoma 0.90 long, 0.70 wide. Sternum 0.45 long, 0.37 wide. Prosoma, sternum and chelicerae yellow; legs, labium, endites pale yellow. Prosoma nearly triangle, with a pair of setae at the retrolateral side of eyes. Six eyes. FIGURE 7.

Chelicerae longer than endites, with two teeth and three tiny granulous denticles on the promargin, and three small triangular teeth on the retromargin of fang furrow ( Figs 15 F). Patellae I–IV with one long macroseta on the distal part of dorsal surface. Tibia I–IV with one long macroseta dorsally (position 0.3). Leg measurements: I 5.00 (1.50, 0.25, 1.60, 1.00, 0.65); II 4.17 (1.40, 0.25, 1.10, 0.87, 0.55); III 2.97 (0.90, 0.22, 0.80, 0.55, 0.50); IV 3.90 (1.25, 0.25, 1.12, 0.75, 0.53). Leg formula: I-II-IV-III. Opisthosoma dark green, covered with long setae. Bulb pale yellow, heart-shaped. Embolus long, beak-shaped, and approximately 1.5 the length of bulb ( Figs 11 A–B, 14A–B). Female (one of the paratypes ). Similar to male in coloration and general features, but with a smaller body size and shorter legs. Total length 1.55 ( Figs 13 A–B). Prosoma 0.62 long, 0.60 wide. Opisthosoma 0.75 long, 0.70 wide. Sternum 0.42 long, 0.36 wide. Leg measurements: I 4.80 (1.50, 0.25, 1.45, 1.00, 0.60); II 4.17 (1.25, 0.25, 1.20, 0.87, 0.60); III 2.72 (0.9, 0.20, 0.75, 0.50, 0.37); IV 3.80 (1.25, 0.25, 1.10, 0.70, 0.50). Leg formula: I-II-IV-III. Genital area with a row of setae on epigynal plate and a row of stout setae posterior to epigastric furrow ( Fig. 15 B). Spermatheca elongate, semicircular in lateral view ( Figs 13 C, 15A). Variation: Total length: males 1.64–1.75 (n = 21), females (1.52–1.60) (n=84). Distribution: China (Guangxi) ( Fig. 38 ), known only from the type locality.
