Tanasevitch, Andrei V., 2006, On some Linyphiidae of China, mainly from Taibai Shan, Qinling Mountains, Shaanxi Province (Arachnida: Araneae), Zootaxa 1325, pp. 277-311 : 284-285

Indophantes ramosus sp. n.

Figs 19–22

Material. Holotype ♂ ( SMF), China, Quinghai Prov., Bei Shan National Park, 120 km NE Xining, 2300–2700 m, 23.V.–8.VI.1996, leg. J. Martens.

Diagnosis. The palp structure of I. ramosus sp. n. resembles that of the Himalayan I. digitulus (Thaler 1987) . The new species is easily distinguishable from it by the bifid cymbial posterodorsal outgrowth, the absence of a tooth­like extension on the posterior part of the paracymbium, as well as by the more deeply divided branches of the lamella characteristica.

Etymology. The specific name is a Latin adjective meaning branching, referring to the shape of the cymbial posterodorsal outgrowth.

Description. Male. Total length––1.95. Carapace 0.90 long, 0.80 wide, brown. Chelicerae 0.40 long. Legs yellow without median bands. Leg I, 4.21 long (1.13+0.25+1.00+1.03+0.80), IV––3.80 long (1.03+0.23+0.93+0.98+0.63). Chaetotaxy. Ti I: 2­1­0­0, II: 2­0­1­0, III–IV: 2­0­0­0; Mt I–IV: 1­0­0­0. TmI––0.24. Palp ( Figs 19–22 ): Cymbium with a pronounced, posterodorsal, bifid outgrowth. Paracymbium with a dentiform extension in posterior part. Lamella characteristica long, with two pointed branches. Terminal apophysis large, well­sclerotised, consisting of two flat lobes. Opisthosoma 1.00 long, 0.88 wide, dorsally pale with a wide grey median stripe in anterior part and several transverse grey stripes posteriorly.

Female. Unknown.
