Etymology.

The specific name derived from the county where the type locality is located and is a noun in apposition.

Diagnosis.

The male of this new species is similar to Zelotes liaoi Platnick & Song, 1986 in having a finger-like RTA, U-shaped sperm duct (SD), a triangular median apophysis (MA) in ventral view and a strong terminal apophysis (TA) with a spine-like apex, but differs by the clearly visible embolic projection (EP) (vs invisible or absent) and by the embolus (Em) with a membranous apex bending toward posterior part of tegulum (vs sclerotized apex bending toward anterior part of tegulum) (Figs 6C-F , 7 vs Song et al. 2004: fig. 158C, D). The female of Z. dingnan can be distinguished from that of Z. liaoi by the teardrop posterior part of the fovea (Fo) (vs subtriangular) and by the copulatory ducts (CD) divided into three parts (anterior, medial, and posterior) (vs two) (Figs 8C, D vs Song et al. 2004: fig. 158A, B).

Sperm duct (SD) U-shaped, originating from near median apophysis. Median apophysis (MA) with a broad base and retrolaterally curved apex. Terminal apophysis (TA) subquadrangular, with a tooth-like apophysis prolaterally and a spine-like apophysis anteriorly. Intercalary sclerite (IS) longer than terminal apophysis, with membranous part anteriorly. Embolic projection (EP) spine-like, covered by the membranous part of intercalary sclerite. Embolus (Em) with a membranous apex directed posteriorly.

Female. Habitus as in Fig. 8A, B . Total length 5.49. Carapace: 2.39 long, 1.85 wide. Eye sizes and interdistances: AME 0.07, ALE 0.09, PME 0.07, PLE 0.08, AME-AME 0.06, AME-ALE 0.03, PME-PME 0.06, PME-PLE 0.06, AME-PME 0.1, AME-PLE 0.13, ALE-ALE 0.23, PLE-PLE 0.32, ALE-PLE 0.06.

Colouration as in male, but paler.

Epigyne (Fig. 8C, D ). Epigyne 1.3 × longer than wide. Anterior pockets (AP) wavy, longer than median pockets (MP). Posterior pockets (PP) poorly visible. Anterior part of fovea (Fo) subrectangular, 1.5 × wider than long. Posterior part of the fovea teardrop-like. Copulatory openings (CO) slit-like, located antero-laterally. Copulatory ducts (CD) consist of three parts: longitudinal anterior part, C-shaped median part, which is 2 × wider than anterior, and swollen posterior part. Lateral glands (LG) twice shorter than median part of copulatory ducts, directed laterally. Spermathecae (Sp) oval, connected with copulatory ducts by a short bending tube. Fertilisation ducts (FD) slightly curved.

Comments.

The holotype male and the paratype female were collected in different localities. Distance between Guizhumao parking lot and Sanbaishan National Forest Park is about 12 km, which is very close. Moreover, both specimens have similar habitus and coloration. For these reasons, we consider them as conspecific. This hypothesis will be confirmed or rejected in future when both sexes are collected together.

Distribution.

Known only from the type locality, Jiangxi Province, China (Fig. 9 ).
