Material examined.

Holotype ♂ (IZCAS AR 27810): CHINA: Taiwan: Kaohsiung City, Shoushan Mountain, 29 June 2013, S. Li, G. Zheng & Y. Tong leg. Paratypes: same data as holotype, 1 ♀ (SYNU-11); same data as holotype, 2 ♀ (SYNU-57).

Etymology.

The specific name is taken from the type locality; adjective.

Diagnosis.

The new species is similar to Xestaspis paulina (see Eichenberger et al. 2012), but can be distinguished by the sternum with short radial furrows between coxae I–II, II–III and III–IV (Figs 8F, 9E), by the lateral carapace surface, which is strongly striated (Figs 8B, D, 9B, D), by the abdominal scuto-pedicel region with only one straight scutal ridge, without a second, upper, semicircular ridge (Fig. 8J, K), and by the male palp with strongly pointed conical extension (ce in Fig. 10A, B).

Description.

Male (holotype). Total length 1.87; carapace 0.82 length, 0.65 width; abdomen 1.09 length, 0.84 width. Habitus as in Fig. 8A, C, E. Body yellow or reddish brown, chelicerae and sternum lighter, legs yellow. Carapace: pars cephalica slightly elevated in lateral view. Carapace dorsally smooth, with two rows of short, finely hairs laterally; sides strongly striated; lateral margin with a row of finely hairs. All eyes oval, about subequal; clypeus height about equal to the diameter of anterior eyes (Fig. 8B, D, G). Sternum with narrow, transverse palpal groove, covered with thin hairs standing in small pits, radial furrows present (Fig. 8F). Abdomen: dorsal scutum ovoid, punctate, densely covered with short hairs. Booklung covers very small, anterolateral edge with tubercle. Pedicel tube short, without dorsolateral extension, scuto-pedicellar region with straight scutal ridge (Fig. 8J, K). Colulus very small, bearing two setae. Genitalia: sperm pore narrow, slit-like. Palp (Fig. 10A, B): cymbium and bulbus yellow. Bulbus distally tapering, ending as pointed conical extension (ce). Cymbium not extending beyond distal tip of bulb. Embolus-conductor complex, mesially bent in dorsal view.

Female (paratype). Total length 2.11; carapace 0.86 length, 0.69 width; abdomen 1.28 length, 1.05 width. Habitus as in Fig. 9A, C. As in male except as noted. Genitalia: ventral view: simple, externally without special features (Fig. 9H, I). Dorsal view: vulva with a small receptaculum and complicated sclerites (Figs 9J, 10C).
