Type material.

Holotype female: Thailand, Chiang Mai Province: Doi Inthanon National Park , [18 ° 35 ′ 24 ″ N, 98 ° 28 ′ 48 ″ E], 1680 m, 24 October 2002, P. Dankittipakul leg. ( MHNG, THI 0068 ).

Etymology.

The specific name is derived from the type locality, the Doi Inthanon National Park; adjective.

Diagnosis.

The female of P. inthanonensis Jäger & Liu , sp. nov. can be distinguished from those of all other Pseudopoda species by the posterior margins of LL with a distinct inverted V-shaped indentation at the middle part.

Female ( THI 0068): Measurements: Medium sized. Body length 12.7, DS length 4.9, width 4.2, OS length 7.8, width 4.5. Eyes: AME 0.24, ALE 0.34, PME 0.27, PLE 0.32, AME – AME 0.19, AME – ALE 0.09, PME – PME 0.21, PME – PLE 0.38, AME – PME 0.30, ALE – PLE 0.26, CH AME 0.36, CH ALE 0.27. Spination: Pp 131, 001, 2121, 1004; Fe I – II 323, III 322, IV 331; Pa I – IV 101; Ti I – IV 2026; Mt I – II 2024, III 3024, IV 3036. Measurement of palps and legs: Pp 7.8 (2.3, 1.8, 1.0, –, 2.7); I 23.8 (7.0, 2.3, 6.9, 6.1, 1.5), II 28.4 (8.1, 2.5, 8.4, 7.3, 2.1), III 18.4 (6.0, 1.5, 5.1, 4.7, 1.1), IV 24.3 (7.3, 1.8, 6.3, 6.9, 2.0). Leg formula: II-IV-I-III. Promargin of chelicerae as in P. baimai Jäger & Liu , sp. nov., cheliceral furrow with c. 27 denticles.

Epigyne (Fig. 5 A – C ): As in diagnosis. EF wider than long, AB long, but indistinct. LL narrow, with anterior margins slightly curved. S oval-shaped in ventral view, covered by FW and posterior part of LL in dorsal view. FD long, suited medially.

Colouration (Fig. 6 A, B ): DS reddish-brown with dark spots. Margins with dash dark dots. Fovea and striae distinctly marked. OS dorsally brown, with several dots at anterior part, with two round patches at the posterior half. OS ventrally yellow, with several brown and irregular marks.

Male: Unknown.

Remarks.

It is possible that this species is conspecific with P. columnacea Zhang, Jäger & Liu, 2023 ( Zhang et al. 2023) due to their shared habitat. However, significant variations in the color and patterns on the dorsal side of the females compared to the males of P. columnacea suggest they could be different species. Clarifying these uncertainties will require additional research and future discoveries.

Distribution.

Thailand (Chiang Mai Province) (Fig. 9 ).
