Type material.

Holotype ♂: China: Jiangxi: Ganzhou City: Ningdu County: Huangguan Village, Taiping Cave, N25°28'53", E115°54'35", elevation: 420 m, 29.IV.2013, Y.F. Luo and J.C. Liu. Paratypes: 10♀, same data as holotype.

Etymology.

The specific name refers to the type locality; adjective.

Diagnosis.

The male of the new species can be easily recognized by the short, broad conductor without a looped apex, the short cymbial furrow (approximately 1/5 length of cymbium, approximately 1/2, 1/3 or 1/4 length of cymbium in other species) and the strong patellar apophysis (twice as broad as in other species) (Fig. 7 A–C). The female of the new species is similar to Spiricoelotes anshiensis sp. n. but can be distinguished by the larger atria (approximately 1/2 of epigynal plate), the epigynal hoods that are separated by twice their width, the slender and horizontally stretched copulatory ducts, the longer and helical spermathecae (Fig. 8 A–B).

Leg measurements: I 14.81 (3.76, 4.81, 3.84, 2.40); II 12.10 (2.82, 3.80, 3.52, 1.96); IV 16.81 (4.25, 5.00, 5.06, 2.50). Chelicerae with three promarginal and four retromarginal teeth. Palp: patellar apophysis subequal to patellar width, strongly curved; RTA with blunt tip, extending slightly beyond distal margin of tibia; LTA long, about 1/2 length of RTA; cymbial furrow short, approximately 1/5 length of cymbium; conductor short, anteriorly extending; embolus beginning at 7 o’clock position; base of embolus wider than tibia, triangular, horizontally directed (Fig. 7 A–C).

Female (one of the paratypes): Total length 7.16. Carapace 3.36 long, 2.56 wide. Abdomen 3.80 long, 2.80 wide. Eye sizes and interdistances: AME 0.14, ALE 0.19, PME 0.16, PLE 0.19; AME-AME 0.06, AME-ALE 0.06, PME-PME 0.10, PME-PLE 0.09. Leg measurements: I 15.12 (4.17, 4.87, 3.20, 2.34); II 13.37 (3.72, 4.25, 3.25, 2.15); III 12.76 (3.44, 3.92, 3.4, 2.00); IV 16.66 (4.68, 5.00, 4.61, 2.37). Chelicerae as in male. Epigyne: atria large, occupying 1/2 of epigynal plate, located anteromedially; hoods distinct, located anterolaterally; spermathecae spiraled; copulatory ducts long and almost horizontally stretched (Fig. 8 A–B).
