Pseudopoda amphitropa Zhang, Jäger & Liu , spec. nov. Figs 10–11 , Map 4

Type material. CHINA, Yunnan Province: Holotype female from Gongshan County, Dulongjiang Township, Dizheng Longyuan Village [28.00°N, 98.33°E], 1690 m, 2 November 2004, D.H. Kavanaugh leg. ( CAS, HNU0005 ).

Etymology. The specific name is derived from the Latin adjective amphitropus, - a, - um, meaning “transverse”, referring to the well visible part of the IDS extending transversally, best seen in ventral view; adjective.

Diagnosis. The female of P. amphitropa Zhang, Jäger & Liu , spec. nov. is similar to that of P. obtusa Jäger & Vedel, 2007 ( Jäger & Vedel 2007) by the shape of the LL and the visible part of the IDS in ventral view as well as the strong and dark lateral bands of the prosoma, but can be distinguished by: 1) Visible part of IDS in ventral view of same width; 2) Lateral parts of LL bulging laterally and with small cavities; 3) Membranous hood between FD wider than long (visible part of IDS in ventral view widened apically, lateral parts of LL evenly rounded and without cavities, membranous hood between FD longer than wide in P. obtusa ).

FEMALE (HNU0005): Measurements: Medium sized. Body length 9.3, DS length 4.2, width 3.6, OS length 5.1, width 3.2. Eyes: AME 0.18, ALE 0.28, PME 0.22, PLE 0.25,AME–AME 0.19,AME–ALE 0.13, PME– PME 0.26, PME–PLE 0.38, AME–PME 0.34, ALE–PLE 0.31, CH AME 0.42, CH ALE 0.36. Spination: Pp 131, 101, 2121, 1014; Fe I–III 323, IV 321; Pa I–IV 101; Ti I–III 2224, IV 2226; Mt I–II 1014, III 2024, IV 3036. Measurements of palps and legs: Pp 5.1 (1.4, 0.7, 1.1, –, 1.9); I 13.0 (3.7, 1.6, 3.4, 3.2, 1.1); II 15.3 (4.2, 1.7, 4.6, 3.5, 1.3); III 11.2 (3.2, 1.4, 2.6, 3.0, 1.0); IV 12.5 (3.9, 0.9, 3.1, 3.4, 1.2). Leg formula: II-I-IV-III. Cheliceral furrow with ca. 31 denticles.

Epigyne ( Figs 10A–C ): As in diagnosis. EF wider than long, AB indistinct. Anterior margins of LL evenly bent, and roughly parallel to posterior margins. IDS covered by FW, membranous hood and posterior part of LL in dorsal view.

Colouration ( Figs 11A–B ): DS yellow with broad reddish-brown lateral bands; striae and fovea distinctly marked in dark brown; sternum vividly spotted. OS dorsally reddish brown, ventrally brown with dark marks and two yellow longitudinal lines.

MALE: Unknown.

Distribution. China (Yunnan Province).
