Type
material.
Holotype ♂: China: Jiangxi: Ganzhou City: Ningdu County: Huangguan Village, Chufeng Cave,
N26°29'35"
,
E115°55'45"
, elevation: 395 m, 29.IV.2013, Y.F. Luo and J. Liu. Paratypes: 6♀, same data as holotype.
Etymology.
The specific name refers to the type locality; adjective.
Diagnosis.
The male of the new species has a uniquely shaped male palp and can be easily distinguished from all other
Spiricoelotes
by the more slender, needle-like conductor (conductor spiralled or with looped apex in other species) and the shorter cymbial furrow (approximately 1/4 length of cymbium, in other species approximately 1/2 length of cymbium) (Fig. 3
A-C
). The female of the new species can be easily
distinguished
from all of the other
Spiricoelotes
by the smaller (subequal to hoods) and posterolaterally situated epigynal atria, the bulb-shaped copulatory ducts and the broader spermathecae (Fig. 4
A-B
).

Leg measurements: I 15.05 (4.23, 5.12, 3.45, 2.25); II 13.55 (3.85, 4.30, 3.35, 2.05); III 12.85 (3.75, 4.05, 3.25, 1.80); IV 16.80 (4.65, 4.95, 4.75, 2.45). Chelicerae with three promarginal and five retromarginal teeth. Palp: patellar apophysis long, subequal to width of patella, with pointed tip, strongly curved; RTA with pointed tip, extending slightly beyond the tibia; LTA short; cymbial furrow short, approximately 1/4 length of cymbium; conductor long, needle-like, anteriorly extending; embolus, beginning at 6
o'clock
