Type material.

Holotype • ♂ ( SWUC -T-THO-01-01 ), China, Xizang, Medog County, Mirage observation deck , 29°20'36"N, 95°20'43"E, elev. 1297 m, 8 July 2023, Z. S. Zhang, L. Y. Wang, Q. L. Lu and X. L. Chen leg. GoogleMaps Paratypes: • 1 ♂ 4 ♀ ( SWUC -T-THO-01-02 ~ 06), same data as for holotype GoogleMaps .

Etymology.

The specific name is derived from the type locality; it is a noun in apposition.

Diagnosis.

The new species resembles C. formosus Thorell, 1887 ( Song and Zhu 1997: 173, fig. 122 A – D) in having the embolus origin in the same position, but C. medog differs from the latter by the short and blunt ventral tibial apophysis end (vs long and sharp in C. formosus ), a bifurcated retrolateral tibial apophysis (vs single in C. formosus ), a broad embolus (vs slender in C. formosus ), and a distinct copulatory atrium (vs indistinct in C. formosus ) (Fig. 4 View Figure 4 ).
