Type material.
Holotype: ♂ (IZCAS-Ar42003), China, Yunnan, Tengchong, Xincheng District, Luoshui Cave, 25.34°N, 98.54°E, ca. 1937 m, 15.VII.2016, Y. Li leg. Paratypes: 2♀ (IZCAS-Ar42004-Ar42005), same data as holotype.
Etymology.
The specific name is a noun in apposition taken from the type locality.
Diagnosis.
The male of Pimoa tengchong sp. nov. resembles those of P. binchuanensis (see Zhang and Li 2019: 3, fig. 1A-C) and P. duiba (see Zhang et al. 2020: 84, fig. 3A-C) but can be distinguished from P. binchuanensis by the short, broad cymbial denticulate process (Fig. 57C View Figure 57 ) (vs. broad and long) and by the distally pointed pimoid embolic process (Fig. 57C View Figure 57 ) (vs. tip with fine granulations) and distinguished from P. duiba by the embolus without a spine (Fig. 57C View Figure 57 ) (vs. with a short, slender spine proximally) and by the distally curved pimoid cymbial sclerite (Fig. 57C View Figure 57 ) (vs. nearly V-shaped). The female of P. tengchong sp. nov. resembles P. duiba (see Zhang et al. 2020: 84, fig. 4A-D) but can be distinguished by the triangular dorsal plate (Fig. 45B View Figure 45 ) (vs. tongue-shaped) and by the medially located fertilization ducts separated by ca. 1/2 width of the dorsal plate (Fig. 45B View Figure 45 ) (vs. smaller separation).

Palp (Figs 44A, B View Figure 44 , 57C View Figure 57 ): patella short, ca. 1/2 of tibial length; tibia short, ca. 1/2 of cymbial length, with several macrosetae and a dorsal process; paracymbium short, ca. 1/3 of cymbial length, hook shaped; pimoid cymbial sclerite L-shaped, distally curved, ca. 1/3 of cymbial length; cymbial denticulate process short and broad, with more than 11 cuspules; median apophysis slender; conductor distinct; pimoid embolic process distally pointed, longer than embolus; embolus beginning at the 7:30 o’clock position, suddenly narrowing distally; embolic tooth absent.

Leg measurements: I: 11.62 (3.28, 4.31, 2.97, 1.06); II: 9.92 (2.97, 3.44, 2.56, 0.95); III: 7.05 (2.15, 2.24, 1.72, 0.94); IV: 9.68 (2.81, 3.23, 2.44, 1.20). Habitus as in Fig. 45E-G View Figure 45 . Carapace yellowish with black lateral margins; thoracic fovea and radial grooves distinct; sternum brownish. Abdomen black with yellowish transverse bands. Legs yellowish with black annulations. Epigyne (Fig. 45A-D View Figure 45 ): triangular; ventral plate broad, width subequal to length; dorsal plate triangular, with a tip distally; copulatory openings distinct; spermathecae oval, with small separation; fertilization ducts membranous, laterally oriented.
