Type material.

Holotype ♀ (IZCAS-Ar 41045) Myanmar: Kachin State, Putao, Hponkanrazi Wildlife Sanctuary, near Camp 3, (27.61352°N, 96.98333°E; 2691 m alt.), 11.V.2017, J. Wu and Z. Chen leg.

Etymology.

The specific epithet derives from the type locality; noun in apposition.

Diagnosis.

This new species is similar to P. jiangzhou sp. nov. and P. nigeri in the shape of the epigyne, the tongue-shaped parmula and the exposed copulatory openings, but it differs from P. jiangzhou sp. nov. by the rounded copulatory openings, the longer copulatory ducts and the larger, reniform spermathecae, rather than trumpet-shaped copulatory openings, shorter copulatory ducts and smaller, oval spermathecae (cf. Figs 11D and F-G vs. 5D and F-G) and from P. nigeri by the longer, twisted copulatory ducts that wrap around the spermathecae, rather than the shorter, straight copulatory ducts that do not wrap around the spermathecae (cf. Figs 11G and 10G ).

Description.

Female (IZCAS-Ar 41045). Total length 0.68. Carapace 0.28 long, 0.28 wide, 0.28 high. Clypeus 0.10 high. Sternum 0.20 long, 0.20 wide. Abdomen 0.52 long, 0.56 wide, 0.56 high. Length of legs: I 0.76 (0.24, 0.08, 0.16, 0.12, 0.16); II 0.68 (0.20, 0.10, 0.12, 0.12, 0.14); III 0.60 (0.18, 0.08, 0.10, 0.12, 0.12); IV 0.74 (0.22, 0.10, 0.16, 0.12, 0.14).

Somatic characters (Fig. 11A-C ). Colouration: carapace centrally yellow, marginally pale brown. Chelicerae brown, endites and labium dark brownish. Sternum centrally yellow, brown at margins. Femora and patella brown-yellow, other segments dark brown. Abdomen light yellow, dark pigmentation around spinnerets and posterior. Prosoma: carapace as long as wide, dorsally pear shaped. ALE> PME> PLE. PME contiguous, PER straight. Chelicerae anterior surface flat, densely covered with short setae. Endites rectangular. Labium subtriangular. Sternum plump, surface smooth, with sparse setae. Legs: all patellae with 1 dorsal seta, tibia I and II with 2 dorsal setae, 1 on tibia III and IV. Metatarsi and tarsi densely covered with fine setae. Opisthosoma: subrounded dorsally, postgaster area with short setae. Spinnerets dark.

Epigyne (Fig. 11D-G ): faintly sclerotised, internal structures faintly visible via the cuticle. Parmula tongue-shaped, protruded, bilateral basal corners concave. Copulatory openings round. Spermathecae kidney shaped, separated by ca. ½ - ⅓ their width. Copulatory ducts long, with a complex course, twisting around the spermathecae nearly 4 times. Fertilisation ducts short, starting at posterolateral margins of spermathecae.

Male. Unknown.
