Type material. THAILAND, Nan Province: Holotype male from Nanthaburi National Park, Doi Wao [19.37°N, 100.70°E], 1510 m, 7 December 2005, P. Dam & T. Chami-kran leg. ( MHNG, THI0014 ) . Paratypes: 10 males, 6 females, with same data as for holotype. ( MHNG, THI0015 – THI0028 ; 1 male, 1 female: SMF) . 1 male, 1 female, Doi Phu Kha National Park [19.20°N, 101.07°E], 1800 m, 9 December 2005, P. Dam & T. Chami-kran leg. ( SMF, THI0031 ) ; 9 males, 4 females, Doi Wao [19.13°N, 100.63°E], 1449 m, 17 December 2002, P. Dankittipakul leg. ( SMF, THI0059 – THI0061 ) ; 5 males, 7 females, Doi Wao , Tha Wang Pha [19.12°N, 100.81°E], 1345 m, 18 December 2002, P. Dankittipakul leg. ( MHNG, THI0062 ) .

Etymology. The specific name is derived from the type locality, the Doi Wao; adjective.

Diagnosis. The male of P. waoensis Zhang, Jäger & Liu , spec. nov. can be recognised from those of other Pseudopoda species by: 1) E broad, with long basal part, its tip sickle-shaped; 2) Both dRTA and vRTA with sharp tips in ventral view. The female of P. waoensis Zhang, Jäger & Liu , spec. nov. is similar to that of P. damana Jäger, 2001 (Jäger 2001) by anterior margins of LL extending longitudinally, but can be distinguished by: 1) Sclerotised part of IDS smaller in ventral view; 2) Posterior margins of LL evenly rounded (sclerotised part of IDS occupying more than half of EF, posterior margins of LL with median incision in P. damana ).

MALE (THI0014): Measurements: Small sized. Body length 7.9–9.2, DS length 3.7, width 3.3, OS length 5.2, width 3.8.

Measurements of palps and legs: Pp 5.3 (1.5, 0.7, 1.0, –, 2.1); I 15.3 (4.4, 1.7, 4.2, 3.8, 1.2); II 20.3 (5.5, 1.9, 6.4, 5.1, 1.4); III 13.6 (4.0, 1.4, 3.7, 3.4, 1.1); IV 16.3 (5.1, 1.2, 4.1, 4.6, 1.3). Leg formula: II-IV-I-III. Cheliceral furrow with ca. 25 denticles.

Palp ( Figs 254A–C ): As in diagnosis. C arising from T at 12:00 o’clock position, basally wrinkled. E arising from T at 6:30–9:30 o’clock position. RTA arising basally to medially from Ti. dRTA straight digitiform, longer than vRTA.

Colouration ( Figs 256A–B ): DS reddish brown with dark spots, submargins with narrow band running like horseshoe, margin with thin dash line and brown patterns. Fovea marked with brown hairs, radial striae with irregular dots. OS dorsally with brown patterns, ventrally with several reddish-brown marks, especially in posterior half in front of spinnerets.

FEMALE (THI0023): Measurements: Small sized. Body length 8.8–9.8, DS length 3.8, width 3.6, OS length 5.7, width 4.7. Eyes: AME 0.18, ALE 0.29, PME 0.23, PLE 0.26, AME–AME 0.15, AME–ALE 0.08, PME–PME 0.18, PME–PLE 0.33, AME–PME 0.28, ALE–PLE 0.22, CH AME 0.37, CH ALE 0.29. Spination: Pp 131, 101, 2121, 1014; Fe I–II 323, III 322, IV 321; Pa I–II 001, III–IV 101; Ti I 1016, II–IV 2026; Mt I–II 1014, III 3024, IV 3036. Measurements of palps and legs: Pp 5.7 (1.6, 0.8, 1.1, –, 2.2); I 14.2 (4.0, 1.8, 3.7, 3.4, 1.3); II 16.8 (4.4, 2.0, 5.0, 3.9, 1.5); III 11.9 (3.7, 1.4, 3.0, 2.8, 1.0); IV 13.5 (4.2, 1.0, 3.3, 3.6, 1.4). Leg formula: II-I-IV-III. Cheliceral furrow with ca. 23 denticles.

Epigyne ( Figs 255A–C ): As in diagnosis. EF almost as long as wide, without AB, with some wrinkles anteriorly. Anterior margins of LL U-shaped. Posterior strongly wound part of IDS located in central of LL, well visible in ventral view, covered by LL in dorsal view. FW covering most of the IDS.
