Type material. THAILAND, Chiang Mai Province: Holotype female from Doi Inthanon National Park

[18.59°N, 98.48°E], 1750 m, 1 May 2000 , P. Dankittipakul leg. ( MHNG, THI0002 ). Paratypes: 1 female, with same data as for holotype ( SMF, THI0003 ); 1 female, Huay Nam Dang National Park , degraded evergreen forest [19.63°N, 99.02°E] , 1000 m, 10 August 2006, P. Dankittipakul leg. ( MHNG, THI0001 ) .

Etymology. The specific name is derived from the type locality, the Chiang Mai Province; adjective.

Diagnosis. The female of P. chiangmaiensis Zhang, Jäger & Liu , spec.nov. is similar to that of P. parvipunctata by having similar wound lateral loops of IDS, but can be distinguished by: 1) Lateral loops of IDS with two twists; 2) Lateral margin of FW convex; 3) Angle between anterior margins of LL acute, about 30° (Lateral loops of IDS with one twist, lateral margins of FW concave medially, and angle between anterior margins of LL about 60° in P. parvipunctata ).

FEMALE (THI0002): Measurements: Medium sized. Body length 14.1–14.8, DS length 6.1, width 5.2, OS length 8.4, width 6.5. Eyes: AME 0.21, ALE 0.34, PME 0.26, PLE 0.32, AME–AME 0.22, AME–ALE 0.14, PME–PME 0.27, PME–PLE 0.49, AME–PME 0.39, ALE–PLE 0.33, CH AME 0.51, CH ALE 0.42.

Measurements of palps and legs: Pp 7.6 (2.1, 1.2, 1.6, –, 2.7); I 21.1 (6.1, 2.3, 5.8, 5.1, 1.8); II 24.1 (6.7, 2.8, 7.0, 5.6, 2.0); III 17.9 (5.3, 1.9, 4.8, 4.4, 1.5); IV 20.2 (6.5, 1.4, 5.1, 5.3, 1.9). Leg formula: II-I-IV-III. Cheliceral furrow with ca. 23 denticles.

Epigyne ( Figs48A–C ):As in diagnosis.EF wider than long, with long, but indistinct AB. Anterior margins of LL forming a ‘V’. LL touching each other only medially. IDS consisting of partly wide tubes, clearly visible in dorsal and ventral view.

Colouration ( Figs 49A–B ): DS reddish brown with dark spots, margin with dark marks. Fovea distinctly marked. OS dorsally with yellow marks, ventrally with several brown marks, irregularly arranged.
