Figs 16A–B , 17A–B , 18A–B , 19

Type material. Holotype female: CHINA: Yunnan Province: Chuxiong City, Mt. Zixi , 25.0039°N, 101.4189°E, 2461 m, 15 May 2014, Yang Zhong & Xiaowei Cao ( CBEE).

Etymology. The specific name is derived from the Latin adjective peronatus, -a, -um, meaning “wearing boots”, referring to the shape of lateral lobes ( Figs 16A , 17A ); adjective.

Diagnosis. This new species can be distinguished from other species in P. daliensis group by the curved anterior margins of lateral lobes and the boot-shaped lateral lobes ( Figs 16A–B , 17A–B ).

Description. Female (holotype): Measurements: Mediaum sized Heteropodinae. Body length 10.5. DS length 4.3, width 4.0, OS length 6.2, width 4.2. Eyes: AME 0.15, ALE 0.21, PME 0.16, PLE 0.18, AME–AME 0.24, AME–ALE 0.12, PME–PME 0.33, PME–PLE 0.39, AME–PME 0.36, ALE–PLE 0.29, CH AME 0.29, CH ALE 0.26. Spination: Pp 131, -, -; Fe I–II 323, III -, IV -; Pa I-, II 0 0 0, III–IV -; Ti I -, II 2228, III–IV -; Mt I–IV -. Measurement of palps and legs (legs III–IV, Pa I, Ti I, Mt I and II, terminal of palps missing): Pp - (1.5,-, -,–,-); I - (4.5, -, -, -, -); II - (4.8, 1.4, 4.2, -, -). Promargin of chelicerae with three teeth, retromargin with four teeth, cheliceral furrow with ca. 20 denticles.

Epigynal field wider than long. The anterior margins of lateral lobes broad “V”-shaped, posterior part of lateral lobes with distinct lateral projections. FW covering most of internal duct except the middle part, spermathecae spoon-shaped ( Figs 16A–B , 17A–B ).

Colouration in ethanol: DS yellow with dark spots and small patches of dark hairs. Fovea and radial furrows distinctly marked. OS dorsally creamy white with reddish-brown patches, laterally spotted, ventrally creamy white with sparser, but larger marks ( Figs 18A–B ).

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