Type material.

Holotype • ♂ (XUC-2014-081), China, Hubei Province, Wuhan City, Hongshan District, Huazhong Agricultural University, 5 Sep. 2014, 30.85°N, 114.71°E, elev. 25 m, F. X. Liu, C. Xu leg. Paratype • 1 ♀ (LH-2017-000), same locality as holotype, 1 Mar. 2017, 30.48°N, 114.35°E, elev. 33 m, F. X. Liu, H. Liu leg. • 1 young female (XUC-2014-082), same data as holotype .

Diagnosis.

This species differs from L. jihe sp. nov., L. davidi, L. pavlovi, and L. stridulans by absence of stridulatory ridges on the chelicerae in both sexes. Male of L. wuhan sp. nov. resembles that of L. jinyun by distinctly curved embolus but can be distinguished from L. jinyun by shorter embolus (Fig. 7 D – F vs Fig. 11 D – I), and from L. zhangping sp. nov. by more slender embolus (Fig. 7 D – F vs Fig. 9 D, E). Female of L. wuhan sp. nov. can be distinguished from other Latouchia species by its incurved spermathecae, with lobes slightly narrower than stalks (Fig. 7 G).

Description.

Male (holotype, Figs 2 C, 3 C, 7 I). Carapace yellowish brown. Cephalic region elevated. Eyes in two rows: anterior row strongly procurved, posterior row straight. Chelicerae concolorous with carapace, without stridulatory ridges, promargin with five teeth, retromargin with four teeth. Fovea procurved and deep. Sternum yellow with glabrous sigilla. Labium and maxillae brown, two maxillae together bearing 40 short, basally thickened setae along proximal edge (Fig. 3 C, 7 I). Opisthosoma brown with regular light blotches.
