Palp (Fig. 1 C-F and Fig. 3 ). Tibia with two apophyses: ventral apophysis (VTA) hook-shaped in ventral view, shorter than tibia, curved prolaterally, with widened base; retrolateral apophysis (RTA) thick, horn-like, with tooth-like apex, longer than tibia. Tegular ridge (TR) broad, arising at 12 o’clock position, extending along tegular margin. Embolus (Em) very thick, with 1.5 spirals clockwise, apex directed at 3 o’clock position.

Colouration (Fig. 2 A and B). Carapace red to dark brown. Chelicerae, endites and labium dark brown. Sternum yellow brown, mottled. Abdomen with a few white spots, distinct symmetrical black-brown stripes from anterolaterally to subposterolaterally and the subtriangular black-brown spot in front of anus.

Epigyne (Fig. 2 C and D and Fig. 3 G and H) two times wider than long. Anteromedian part with septum (Se) dividing atrium (At) into two large oval parts. Copulatory openings (CO) located at posterior part of the fovea. Copulatory ducts (CD) almost straight, not in a line, shorter than spermathecal width. Spermathecae (Spe) anticlockwise coiled, forming one full turn, slightly separated by nearly 1/3 of its maximum width (in some specimens). Fertilisation duct indistinct.

Comments. In life (Fig. 4 ), this species exhibits dark colours in most parts of the legs and abdomen, while yellowish after preservation in ethanol.

Diagnosis

The male of this new species is similar to that of Lysiteles torsivus Zhang, Zhu & Tso, 2006 ( Tang et al. 2008: 34, fig. 18a-e) in having a hook-shaped ventral tibial apophysis and thick cone-shaped retrolateral apophysis, but can be easily distinguished from it by (Fig. 1 ) the carapace lacking pair of broad yellow-brown stripes (vs present in L. torsivus ) and the anterior part of embolus with 1.5 spirals (vs 1.25 in L. torsivus ). The female of the new species resembles those of L. auriculatus Tang, Yin, Peng, Ubick & Griswold, 2008 ( Tang et al. 2008: 6, fig. 2a-e), L. spirellus Tang, Yin, Peng, Ubick & Griswold, 2008 ( Tang et al. 2008: 31, fig. 16a-f), L. subspirellus Liu, 2022 ( Liu et al. 2022c: 55, fig. 7A, C, D) in having anticlockwise spiral spermathecae, but can be separated by (Fig. 2 A, C and D) the longitudinal dark brown stripes covered 1/3 of dorsal abdomen (vs nearly 1/2 in L. auriculatus and L. spirellus , more than 2/3 in L. subspirellus ) and the spermathecal end directed at 7 o’clock (vs 5 o’clock in L. auriculatus , 9 o’clock in L. spirellus , 6 o’clock in L. subspirellus ).

Etymology

The specific name refers to the type locality; noun in apposition.

Distribution

Known only from the type locality in Jiangxi Province, China (Fig. 5 ).
