Type material.

Holotype ♂: China: Hainan: Qiongzhong County: Mt. Limushan, Pine forest, N19°10'53", E109°45'20", 537 m, 2.XII.2015, X. Zhang & Z. Chen. Paratypes: 2♀3♂, same data as holotype; 1♀, same area, N19°10'55", E109°45'17", 637 m, 3.V.2011, Y. Zhou.

Etymology.

The specific name refers to the type locality; adjective.

Diagnosis.

The male of Notiocoelotes qiongzhongensis , sp. n. can be distinguished from all of the other Notiocoelotes species, except Notiocoelotes pseudolingulatus and Notiocoelotes sparus , by having posteriorly extended conductor and cymbial furrow almost half of cymbial length. From the latter two species, it can be distinguished by the semicircular conductor apex (while Notiocoelotes pseudolingulatus has a blunt apex, and Notiocoelotes sparus has an acute apex) (cf. Fig. 5 A–C; Liu and Li 2010: figs 10-11; Dankittipakul et al. 2005: figs 1-3). The female of Notiocoelotes qiongzhongensis , sp. n. can be distinguished from all Notiocoelotes , except Notiocoelotes orbiculatus and Notiocoelotes parvitriangulus , by the rounded receptacles. It can be distinguished from Notiocoelotes orbiculatus by the head of receptacles situated on anterior part of receptacles (while the head of receptacles is situated on posterior part of receptacles in Notiocoelotes orbiculatus ); and it can be distinguished from Notiocoelotes parvitriangulus by the nearly square-shaped atrium (while Notiocoelotes parvitriangulus has a triangular atrium) (cf. Fig. 6 A–B; Liu and Li 2010: fig. 7B; Liu et al. 2010: fig. 78A).
