Type material. Holotype male: CHINA: Yunnan Province: Bai Autonomous Prefecture of Dali, Eryuan County, Mt. Yueling , 26.11°N, 99.94°E, 2136 m, 18 May 2014, Yang Zhong & Xiaowei Cao leg. ( CBEE). Paratypes: 9 females, with same data as holotype.

Etymology. The specific name is derived from the Latin adjective anguilliformis , -is, -e, meaning eel-shaped and referring to the eel-shaped spermathecae in dorsal view ( Figs 2D , 4D ); adjective.

Diagnosis. This new species can be distinguished from other members of the P. daliensis group by the slightly smaller tegulum, the large embolus covering most of the tegulum, the RTA arising from proximal half of tibia with dRTA showing narrow finger-shaped tip, the wrinkled and very broad epigyne, as well as the long and straight spermathecae ( Figs 2A–D , 3A–B ).

Description. Male (holotype): Medium sized Heteropodinae. Body length 10.7. Measurements: DS length 5.1, width 4.9, OS length 5.6, width 3.6. Eyes: AME 0.17, ALE 0.23, PME 0.19, PLE 0.20, AME–AME 0.28, AME–ALE 0.16, PME–PME 0.38, PME–PLE 0.41, AME–PME 0.37, ALE–PLE 0.35, CH AME 0.35, CH ALE 0.30. Leg formula: II-I-IV-III. Spination: Pp 131, 101, 2101; Fe: I–III 323, IV 331; Pa: I–II 101, III 100, IV 000; Ti: I–II 2128, III–IV 2126; Mt: I–III 2024, III 3034, IV 3036. Measurement of palps and legs: Pp 7.6 (2.4, 0.8, 1.5, –, 2.9); I 23.7 (6.8, 2.1, 5.8, 6.9, 2.1); II 25.4 (7.0, 2.7, 6.2, 7.1, 2.4); III 20.9 (6.2, 2.1, 5.4, 5.3, 1.9); IV 22.7 (6.5, 1.9, 5.6, 6.7, 2.0). Promargin of chelicerae with three teeth, retromargin with four teeth, cheliceral furrow with ca. 24 denticles.

Palp as in diagnosis. Embolus arising from 10- to 11-o’clock-position from tegulum, with covering most part of conductor, with middle part depressed. Spermophor indistinct in embolus. RTA arising proximally from Ti, ventral RTA and dorsal RTA folding towards each other, roughly forming a column ( Figs 2A , 3A–B , 4A–B ), vRTA broad in retrolateral view, dRTA with finger-shaped extension distally.

Colouration in ethanol: DS light yellow with black markings, fovea and radial furrows distinctly marked. OS dorsally with alternating light yellow with reddish-brown patches, partly fused, laterally spotted, ventrally with reddish-brown marks arranged symmetrically ( Figs 5A–B ).

Female: Measurements: Medium sized Heteropodinae. Body length 10.9–13.1. DS length 4.6, width 4.4, OS length 4.9, width 3.5. Eyes: AME 0.18, ALE 0.23, PME 0.19, PLE 0.20, AME–AME 0.24, AME–ALE 0.13, PME–PME 0.33, PME–PLE 0.41, AME–PME 0.37, ALE–PLE 0.35, CH AME 0.39, CH ALE 0.36. Leg formula: II-I-IV-III. Spination: Pp 131, 101, 2121, 1014; Fe I–III 323, IV 331; Pa I–II 0 0 1, III–IV 000; Ti I–II 2128, III–IV 2126; Mt I–II 2024, III 3034, IV 3 0 36. Measurements of palps and legs: Pp 5.8 (1.8, 0.6, 1.5, –, 1.9); I 16.4 (5.2, 1.5, 4.0, 3.8, 1.9); II 16.8 (5.0, 1.6, 4.9, 4.1, 1.2); III 13.9 (4.6, 1.3, 3.7, 3.0, 1.3); IV 15.0 (3.8, 1.9, 3.8, 3.9, 1.6). Cheliceral furrow with three anterior and four posterior teeth, and with ca. 18 denticles.

Epigyne significantly wider than long, with both anterior and posterior margins distinctly wrinkled. Posterior part of lateral lobes with small lateral projections. The long and slender loops of internal duct system slightly extending laterally beyond first winding. Spermathecae long and straight. The fertilisation ducts situated medially ( Figs 2B–D , 4C–D ).

Colouration in ethanol: As in male, but with patches on OS lighter. ( Figs 5C–D ).

Distribution. China (Yunnan) ( Fig. 19 ).
