Pseudopoda complanata Zhang, Jäger & Liu , spec. nov. Figs 62–64 , Map 2

Type material. THAILAND, Phitsanulok Province: Holotype male from Nakhon Thai District, Phu Hin Rongkla National Park [16.99°N, 101.01°E], 1290 m, 23 December 2013, P. Schwendinger leg. ( MHNG, THI0034 ) . Paratypes: 2 males, 9 females, with same data as for holotype ( MHNG; 1 male, 1 female: SMF; THI0035 – THI0047 ) .

Etymology. The specific name is derived from the

Latin adjective complanatus, - a, - um, meaning “flattened”, referring to the flat terminal part of the E; adjective.

Diagnosis. The male of P. complanata Zhang, Jäger & Liu , spec. nov. is similar to that of P. chauki Jäger, 2001 (Jäger 2001) by having: 1) E long, slightly S-shaped; 2) dRTA long, finger-shaped, but can be distinguished by: 1) Cymbium narrow and long; 2) E widened apically; 3) Proximal T narrow, i.e. half of T width (Cymbium broad, E tapering apically, proximal T broad in P. chauki ). Females of P. complanata Zhang, Jäger & Liu , spec. nov. is similar to those of P. sinapophysis Jäger & Vedel, 2007 ( Jäger & Vedel 2007) by having a similar epigynal arrangement and almost oval IDS, but can be distinguished by: 1) LL touching each other at the middle line for half of the epigyne length; 2) LL and large parts of IDS extending posteriorly distinctly beyond the epigastric furrow (LL touching each other only slightly in one point, LL extending only barely beyond epigastric furrow in P. sinapophysis ).

Epigyne ( Figs 63A–C ): As in diagnosis. EF roughly as long as wide, without long AB. Anterior margins of LL forming a ‘V’. Posterior part of IDS hidden in LL in dorsal view. FW covering partly IDS.

Colouration ( Figs 64C–D ): As in male, but generally darker.

Distribution. Thailand (Phitsanulok Province).

Variation. Males:Tip of dRTA and tooth between RTA and tibia slightly longer than those in holotype. Females: Angle between anterior margins of LL larger than 90° (90° in paratype). Spherical lateral loops relatively bigger than that in paratype, i.e. diameter of loop fitting 3 times in FW (only two times in paratype).
