Holotype.

Female (XUX-2011-001), Bawangling, Changjiang County, Hainan Province, China, 19.04°N, 109.09°E, 657 m, collected 19 June 2011 by D. Li, F. Liu, M. Kuntner and X. Xu, deposited at CBEE, College of Life Sciences, Hubei University, Wuhan, China.

Paratypes.

2 females and 2 juveniles (XUX-2012-(094-097)), Bawangling Nature Reserve, Bawangling, Changjiang County, Hainan Province, China, 19.24°N, 109.38°E, 462 m, collected 19-20 July 2012 by D. Li, F. Liu and X. Xu; 1 female (XUX-2014-012) collected at the same locality, 19.03°N, 109.10°E, 711 m, collected 23 March 2014 by F. Liu and C. Xu.

Etymology.

The species epithet, a noun in apposition, refers to the type locality.

Diagnosis.

Females of the new species differ from Q. jianfeng sp. n. by the two pairs of receptacular clusters along the anterior margin of bursa copulatrix, which are visible in both dorsal and ventral views (Fig. 1C-H). It can be distinguished from Q. baishensis and Q. nui by its receptacular clusters with similar size or the middle pair being slightly smaller than the lateral pair. It also differs from all other Qiongthela species in Hainan by its receptacular clusters, all of which have short genital stalks (Fig. 1C-H). The male is unknown. To facilitate future identification of the species, we provided the DNA barcode for the holotype (XUX-2011-001), which is available on GenBank (Genbank accession code KP229897).

Description.

Female (Fig. 1B). Carapace dark brown; opisthosoma darker than carapace; sternum narrow; a few long pointed hairs running over ocular mound in a longitudinal row; chelicerae robust with promargin of cheliceral groove containing 9-10 denticles of variable size; legs with strong hairs and spines; opisthosoma with 12 tergites, close to each other, the fifth largest; seven spinnerets. Measurements: BL 15.75-30.35, CL 8.37-15.95, CW 7.88-12.50, OL 7.42-16.50, OW 5.75-15.50; ALE> PLE> PME> AME; palp 24.10 (8.25 + 4.35 + 5.15 + 6.35), leg I 25.80 (8.45 + 4.75 + 5.05 + 5.00 + 2.55), leg II 24.70 (7.65 + 4.50 + 4.85 + 5.00 + 2.70), leg III 26.80 (7.85 + 4.80 + 4.70 + 6.10 + 3.35), leg IV 37.80 (11.00 + 5.85 + 6.95 + 9.45 + 4.55).

Female genitalia. Two pairs of receptacular clusters along the anterior margin of bursa copulatrix, similar size or the middle pair slightly smaller, with short genital stalks (Fig. 1 C–D)
