Type material.

Holotype ♂: China: Jiangxi: Yichun City: Wanzai County: Shuangqiao Town, Nanshe Cave, N28°10'8", E114°17'16", elevation: 195 m, 15.V.2013, Y.F. Luo and J.C. Liu. Paratypes: 1♂10♀, same data as holotype.

Etymology.

The specific name refers to the type locality; adjective.

Diagnosis.

The male of the new species has uniquely shaped palps and can be easily recognized from all of the other Spiricoelotes species by the extremely modified conductor (with two outgrowths at the base, only one in Spiricoelotes anshiensis sp. n., and none in other species), the looped apex (Fig. 5 A–C). The female of the new species is similar to Spiricoelotes chufengensis sp. n. but can be distinguished from it by the larger and anteriorly situated atria, the more slender and longer copulatory ducts, the longer, more slender spermathecae that are separated from each other by copulatory ducts (Fig. 6 A–B).
