Diagnosis. The male of this species is similar to that of Charippus denjii Yu, Maddison & Zhang, 2022 (Yu et al. 2022: 166, figs 85, 86) in having the bifurcated retrolateral tibial apophysis and the anticlockwise spiraling embolus arising from 9 o’clock on tegulum and ending at ~ 12 o’clock on cymbial tip, but can be easily distinguished from it by the tibia with a thumb-like apex (vs pincer-like) (cf. Figs 1 D, E, 12 A and Yu et al. 2022: 166, figs 85, 86). The female also resembles that of C. denjii in having the heart-shaped atrium and the C-shaped anterior part of copulatory ducts, but can be separated from it by the posterior part of copulatory duct swerving for 7 × (vs 6 ×) and the strongly swollen spermathecae far from (vs close to) the last turn (cf. Fig. 2 C, D and Yu et al. 2022: 166, figs 90–93). Description. Male (holotype). Habitus (Fig. 1 A, B). Total length 4.54. Carapace (Fig. 1 A).
