Type material.

Holotype: ♂ (IZCAS-Ar40310), China, Tibet, Lhoka, Cona County, Senmuzha Scenic Area, 27.83°N, 91.73°E, elevation ca. 2845 m, 10.VIII.2018, X. Zhang and J. Liu leg. Paratypes: 1♂2♀ (IZCAS-Ar40311-40313), same data as holotype; 1♂1♀ (IZCAS-Ar40314-40315), Cona County, Yelang Valley, 27.87°N, 91.81°E, elevation ca. 3379 m, 13.VIII.2018, X. Zhang and J. Liu leg.

Etymology.

The specific name is a noun in apposition taken from the type locality.

Diagnosis.

The male of Pimoa cona sp. nov. resembles P. nematoides Hormiga, 1994 (see Hormiga 1994a: 71, figs 285-289) and P. sinuosa Hormiga, 1994 (see Hormiga 1994a: 67, figs 256-265) but can be distinguished by the large pimoid cymbial sclerite that is subdistally wide and distally pointed (Fig. 1B View Figure 1 , vs. small and distally curved in P. nematoides ; vs. slender and distally blunt in P. sinuosa ); distinguished from P. nematoides by the long tibia, ca. 1/2 of the cymbial length (Fig. 1A-C View Figure 1 , vs. short tibia, ca. 1/3 of cymbial length); distinguished from P. sinuosa by an embolus that begins at the 2:00 o’clock position (Fig. 1B View Figure 1 , vs. an embolus that begins at the 5:30 o’clock position). The female of P. cona resembles P. sinuosa (see Hormiga 1994a: 67, figs 266-284) but can be distinguished by the pair of oval spermathecae (Fig. 2A View Figure 2 , vs. subtriangular spermathecae) and by the subdistally narrow dorsal plate (Fig. 2C View Figure 2 , vs. subdistally wide).
