Notes.

These two collection localities of males and a female of this species are very close and located on both sides of Shenshan Mt. They are assigned in different two adjacent towns in Jinggang Mountain National Nature Reserve, Jiangxi Province, China. Meanwhile, one sub-adult male was also collected on 8 August 2015, which has the same habitus as the males collected on April 5 2014. These males are therefore recognised as corresponding to the conspecific female.

Diagnosis.

This species is easily distinguished from other Phrurolithidae spiders by the following combination of morphological characteristics: (1) lacking a layer of black pigment around the PME (Figs 1A, D View Figure 1 , 3A View Figure 3 ) (vs. PME with black pigment); (2) lacking distinct longitudinal and radial stripes on the dorsal carapace (Figs 1A, D View Figure 1 , 3A View Figure 3 ) (vs. black longitudinal or radial stripes present); (3) lacking chevron-shaped marking on abdominal dorsum (Figs 1A View Figure 1 , 3A View Figure 3 ) (vs. with at least two chevron-shaped markings); (4) male palpal tibia with a single retrolateral apophysis (Figs 2A-C View Figure 2 , 6A, B, D View Figure 6 ) (vs. two tibial apophyses present); (5) female epigyne (Fig. 3C, D View Figure 3 ) with the glandular appendages slender (vs. relatively short and thick), and the spermathecal tail club-shaped (vs. without a spermathecal tail).

Colouration (Fig. 1A-C View Figure 1 ). Carapace yellow, with indistinct radial stripes from median to marginal. Chelicerae, endites, labium, and sternum yellow. Legs yellow, with dark strips on patellae, tibiae and metatarsi I-IV (Figs 1 View Figure 1 , 5 View Figure 5 ). Abdomen yellow, with pair of large oval dark spots medially, pair of blade-shaped dark spots on sub-medial part, and semi-circular dark spot posteriorly.

Palp (Figs 2 View Figure 2 , 6 View Figure 6 ). Femoral apophysis well-developed, width slightly less than half of length, with abundant short setae. Patella unmodified. Tibia with a large retrolateral apophysis, longer than tibia, with sharply pointed and broad base. Cymbium approximately two times longer than wide. Bulb oval, with long V-shaped sperm duct, apophyses absent. Embolus hook-shaped, small, with large base, accompanied by a small tegular apophysis of embolic base, terminal apophysis slightly longer than embolus and surrounded by the embolic base.

Copulatory ducts and gland appendages distinctly visible through integument in intact epigyne. Copulatory ducts slender, curved forward, connecting with the oval bursae. Connecting tubes slender, ear-shaped, located at the distal of copulatory ducts, curved backwards to spermathecae, posteriorly with slender glandular appendages.
