Coelotes tiantangensis, Luo & Chen, 2015

Luo, Ying & Chen, Jian, 2015, Two new Coelotes species from China (Araneae: Agelenidae: Coelotinae), Zoological Systematics 40 (3), pp. 258-267 : 264-267

Coelotes tiantangensis sp. nov. ( Figs 15–29 )

Material examined. Holotype ♂, Tiantangzhai National Forest Park , Hubei Province, China, 27 September 2012, leg. Ying Luo and Jie Liu. Paratypes: 8♀, same data as holotype ; 4♂, Tiantangzhai National Forest Park , Anhui Province, 28 September 2009, leg. Hai-Juan Xie and Xin Xu. All specimens are deposited in CBEE .

Etymology. The specific name is an adjective, referring to the type locality, Tiantangzhai, in which “Tiantang” means paradise, and “zhai” means stockaded village.

Diagnosis. This new species is similar to C. obtusangulus sp. nov., but can be distinguished from the latter by the shorter patellar apophysis, the RTA with distal end not extending beyond tibia, the large epigynal teeth closed with each other ( Figs 2 , 4 , 16 , 18 ). More details can be seen under the above diagnosis of C. obtusangulus sp. nov.
