The specific name is named after the type locality, Medog County; noun in apposition.

Diagnosis.

Pancorius medog sp. nov. resembles that of P. nyingchi Wang, Mi & Li, 2024 in having a central epigynal hood (H), longitudinal band on the dorsum of abdomen, but can be easily distinguished by the following: 1) epigynal hood opened posteriorly (Fig. 20 A) vs opened ventro-posteriorly (Wang et al. 2024: fig. 12 A); 2) the distinct spermathecae (S) (Fig. 20 B) vs indistinct (Wang et al. 2024: fig. 12 B); 3) presence of central yellow area bearing pale thin setae on carapace (Fig. 20 C) vs absent (Wang et al. 2024: fig. 12 E).
