Type material.

Holotype ♀: China: Sichuan Province: Muli County, N27°54'57", E101°16'20", 2229 m, 13.XI.2013, Y. Li and J. Liu.

Etymology.

The specific name refers to the type locality; adjective.

Diagnosis.

The female of the new species has uniquely shaped epigyne and can be easily distinguished from all other Sinocoelotes gen. n. species by the anteriorly situated atrium (atrium with distinct anterior margin, but lacking distinct posterior margin, and the posterior part broader than anterior part), the teeth broad and located between two atrial lateral margins, the long and strongly twisted spermathecae, closely spaced, the slender, mesally originating spermathecal heads (which are also mesally originating in Sinocoelotes luoshuiensis sp. n, but are 1/4 length shorter than those in Sinocoelotes muliensis sp. n.; laterally originating in all other species) (Fig. 15 A–B).

Description.

Female. Total length 5.76. Carapace 2.56 long, 1.72 wide. Abdomen 3.20 long, 1.87 wide. Eye sizes and interdistances: AME 0.09, ALE 0.16, PME 0.12, PLE 0.13; AME-AME 0.07, AME-ALE 0.02, PME-PME 0.08, PME-PLE 0.10. Leg measurements: I: 5.97 (1.73, 2.08, 1.38, 0.78); II: 5.40 (1.62, 1.80, 1.24, 0.74); III: 5.12 (1.50, 1.60, 1.30, 0.72); IV: 7.03 (1.94, 2.31, 1.83, 0.95). Chelicerae with 3 retromarginal teeth. Epigyne: atrium located anteriorly, occupying 1/4 of epigynal plate square, with distinct anterior margin, but lacking distinct posterior margin; teeth broad and long, located on the lateral margins of the atrium; spermathecae narrowly separated from each other, posterior part of spermathecae about 1/4 the anterior part; spermathecal heads slender and long, close to each other; copulatory ducts much thin ner than anterior part of spermathecae (wider in some species), short (about 1/3 length of epigyne), membranous (Fig. 15 A–B).

Male. Unknown.
