Etymology. The specific epithet is in honor of Dr. Fred R. Wanless (1940–2017), who contributed extraordinarily to the taxonomy and comparative morphology of jumping spiders.
Diagnosis. Both sexes closely resemble Euochin longyangensis comb. nov. in genitalic structure. Males of these two species can be recognized by: (1) the portion between the embolic flange and the embolus deeply depressed in E. longyangensis comb. nov., while not depressed in E. wanlessi sp. nov., and (2) the central part of the embolus without a ridge in E. longyangensis comb. nov., but with a ridge in E. wanlessi sp. nov. (cf. Figs 94–97 View FIGURES 94–99 , 100–101 View FIGURES 100–103 , 179–182 View FIGURES 179–184 , 185–186 View FIGURES 185–188 ). Females of the two species can be distinguished by: (1) the epigynal window larger in E. longyangensis comb. nov., while evidently smaller in E. wanlessi sp. nov., and (2) the copulatory duct thicker in E. longyangensis comb. nov. than in E. wanlessi sp. nov. (cf. Figs 98–99 View FIGURES 94–99 , 102–103 View FIGURES 100–103 , 183–184 View FIGURES 179–184 , 187–188 View FIGURES 185–188 ). The female of the new species is also similar to E. mii in the epigynal structure, but can be distinguished by the thicker and longer copulatory duct (vs. thinner and shorter in E. mii , see Wang & Li 2022: fig. 6B). The females of the new species also share genitalic similarities with E. subwanyan , but can be distinguished by the obviously smaller epigynal window ( Figs 183 View FIGURES 179–184 , 187 View FIGURES 185–188 , vs. larger epigynal windows in E. subwanyan , see Wang & Li 2020a: figs 6A–B).
Description. Male. Habitus see Figs 170–171 View FIGURES 170–173 , 174, 176 View FIGURES 174–178 . Carapace length 1.610; abdomen length 1.362. Eye measurements: AME 0.360, ALE 0.235, PME 0.055, PLE 0.196. Leg measurements: I 3.281 (1.031, 0.477, 0.777, 0.599, 0.397), II 2.417 (0.809, 0.358, 0.482, 0.398, 0.370), III 2.590 (0.913, 0.302, 0.537, 0.545, 0.293), IV 2.800 (0.933, 0.336, 0.610, 0.584, 0.337); leg formula: 1432. Color in ethanol: carapace dark brown, with white setae. Abdomen yellowish-brown, with light yellowish-white bands and spots. Chelicera ( Fig. 178 View FIGURES 174–178 ) with two promarginal and one retromarginal teeth. Palp ( Figs 179–182 View FIGURES 179–184 , 185–186 View FIGURES 185–188 ): distal femur and patella covered with long white setae; embolic disc slightly concaved centrally, plane of disc nearly facing ventrally; embolus straight and pointed, with longitudinal ridge medially, and with relatively small flange; cymbial flange marked; RTA tapered.
Female. Habitus see Figs 172–173 View FIGURES 170–173 , 175, 177 View FIGURES 174–178 . Carapace length 1.607; abdomen length 2.104. Eye measurements: AME 0.346, ALE 0.228, PME 0.070, PLE 0.207. Leg measurements: I 2.567 (0.832, 0.398, 0.661, 0.342, 0.334), II 2.337 (0.794, 0.344, 0.478, 0.420, 0.301), III 2.886 (1.036, 0.381, 0.542, 0.503, 0.424), IV 3.292 (1.044, 0.353, 0.701, 0.653, 0.541); leg formula: 4312. Color in ethanol: similar to that of male, but lighter in coloration. Chelicera as in male. Epigyne ( Figs 183–184 View FIGURES 179–184 , 187–188 View FIGURES 185–188 ): epigynal window separated by broad median septum; copulatory opening located interiorly on edge of median septum; copulatory duct connected centrally to inner rim of spermatheca; spermatheca ovoid, evidently larger than epigynal window in ventral view.
Distribution. China (Yunnan).
