Diagnosis.

This species differs from L. jihe sp. nov., L. davidi, and L. stridulans by absence of stridulatory ridges on the chelicerae in both sexes. Male of L. wufeng sp. nov. resembles that of L. zhangping sp. nov. in having slightly thick embolus but can be distinguished by serrulate embolic keel visible in retrolateral view (Fig. 6 F vs Fig. 9 E) and by subterminal protuberance connected to a hook-shaped apex (Fig. 6 D, E vs Fig. 9 D, E). Females of L. wufeng sp. nov. differ from L. zhangping sp. nov. by spermathecae with less distinct constriction between lobes and stalks (Fig. 6 G – J vs Fig. 10 A – G).

Description.

Male (holotype, Figs 2 B, 3 B). Carapace yellowish brown. Cephalic region smoothly elevated. Eight eyes in two rows: anterior row procurved, posterior row straight. Chelicerae concolorous with carapace, promargin with six teeth, retromargin with three teeth. Fovea procurved and deep. Sternum pale yellow with sigilla. Labium and maxillae pale yellow, without cuspules (Fig. 3 B). Opisthosoma brownish-black with regular light blotches.

Patellae and tibiae of legs I and II with stout spines, several bearing hooked tips (Fig. 13 C, D).

Palp. Palpal bulb simple and pyriform in prolateral view; embolus thick, slightly curved at one-third of its length from apex; embolic keel serrulate in retrolateral view; apex with subterminal protuberance connected to a hook-shaped structure, both prolateral and retrolateral superior keels present (Fig. 6 A – F).

Female (HAL-2022-019 B, Figs 2 H, 3 H). Carapace yellowish brown, cephalic region elevated. Eyes in two rows: anterior row procurved, posterior row straight. Chelicerae brown, without stridulatory ridges, promargin with six teeth, retromargin with three teeth. Fovea procurved and deep. Sternum brown with indistinct sigilla. Labium and maxillae brown, labium with three cuspules, two maxillae together bearing 52 cuspules along proximal edge (Fig. 3 H). Opisthosoma dark brown with light blotches.

Vulva. Spermathecae paired with indistinct subcentral constriction; entire spherical lobes and most of stalks densely covered with glandular pores (Fig. 6 G – J).

Variation.

Females vary in body size and number of cheliceral teeth. Measurements for females (N = 7) are as follows: BL 12.23–16.55, CL 4.21–6.65, CW 4.14–6.15, OL 5.64–7.36, OW 4.12–5.16. Promarginal cheliceral teeth: 5–6. Spermathecae either parallel (Fig. 6 G, J) or slightly tilted outward (Fig. 6 H, I).
