Type material.

Holotype ♂: China: Hainan: Baoting County: Maogan Village, Xiananshilin Cave, N18°35'52", E109°25'37", 616 m, 26.VI.2014, F. Li & X. Wang. Paratype: 1♀, same data as holotype.

Etymology.

The specific name refers to the type locality; adjective.

Diagnosis.

The male of Notiocoelotes maoganensis sp. n. can be easily distinguished from all other Notiocoelotes species, except Notiocoelotes palinitropus , by having a semi-circular conductor. From Notiocoelotes palinitropus , the male of the new species can be distinguished by the short cymbial furrow about 1/3 of cymbial length (while Notiocoelotes palinitropus male has a long cymbial furrow, about 0.5 times as long as cymbial length) (cf. Fig. 1 A–C; Zhu and Wang 1994: figs 19-21). The female of Notiocoelotes maoganensis sp. n. can be easily distinguished from all the other Notiocoelotes species, except Notiocoelotes palinitropus , by the almost rectangular atrium. From Notiocoelotes palinitropus , the female of the new species can be distinguished by a broad atrium, about two times as long as wide (while Notiocoelotes palinitropus female has a narrow atrium, about three times as long as wide) (cf. Fig. 2 A–B; Liu and Li 2010: fig. 9B).
