Female (XUX-2012-106, matured 18 July 2013 at CBEE, College of Life Sciences, Hubei University), Jianfengling National Forest Park, Jianfeng Town, Ledong County, Hainan Province, China, 18.70°N, 108.86°E, 764 m, collected 22 July 2012 by D. Li, F. Liu and X. Xu, deposited at CBEE, College of Life Sciences, Hubei University, Wuhan, China.

Etymology.

The specific epithet honors the arachnologist Changmin Yin, a pioneering liphistiid specialist in China.

Diagnosis.

The female of the new species differs from the other Qiongthela species by the receptacular clusters with less granula, the middle pair larger than the lateral pair, the middle pair along the anterior margin of bursa copulatrix, and the lateral pair located on the dorsal wall of the bursa copulatrix (Fig. 3B-C). The male is unknown. The DNA barcode of the holotype (XUX-2012-106) is available on GenBank (Genbank accession code KP229895) for facilitating future identification of the species.

Measurements: BL 20.50, CL 8.00, CW 7.21, OL 12.40, OW 10.00; ALE> PLE> PME> AME; palp 13.54 (4.70 + 2.43 + 2.80 + 3.61), leg I 15.90 (5.10 + 2.80 + 3.11 + 3.20 + 1.69), leg II 15.35 (4.70 + 2.80 + 2.79 + 3.41 + 1.65), leg III 13.85 (4.35 + 2.10 + 2.60 + 3.00 + 1.80), leg IV 23.71 (7.00 + 3.35 + 4.18 + 6.30 + 2.88).

Female genitalia. The middle receptacular clusters along the anterior margin of bursa copulatrix, the lateral pair located on the dorsal wall of the bursa copulatrix, the middle pair larger than the lateral pair, and the middle pair with short genital stalks (Fig. 3B).

Distribution.

Hainan (Jianfeng), China.

Remarks.

This new species was found at the Jianfengling National Forest Park as some specimens of Q. jianfeng sp. n., but at a higher altitude compared with the latter.
