Pseudopoda langyaensis Zhang, Jäger & Liu , spec. nov. Figs 139–141 View FIGURE 139 View FIGURE 140 View FIGURE 141 , Map 4 View MAP 4

Type material. CHINA, Yunnan Province: Holotype male from Baoshan City, Tengchong County, Langya Mountain , 25.49°N, 98.27°E, 2095 m, 11 June 2014, X. GoogleMaps

Cao & Y. Zhong leg. ( CBEE, LJ01812 ). Paratypes: 1 male, 1 female, with same data as for holotype ( CBEE, LJ01813 , LJ01882 ); 3 males, 3 females, Baoshan City , Tengchong County, Ruidian Town , Yunfeng Mountain, 25.38°N, 98.41°E, 2269 m, 10 June 2014 GoogleMaps , X. Cao & Y. Zhong leg. ( CBEE, LJ01806 – LJ01811 ) .

Etymology. The specific name is derived from the type locality, Langya Mountain; adjective.

Diagnosis. The male of P. langyaensis Zhang, Jäger & Liu , spec. nov. is similar to that of P. daxing by having the E extremely expanded, covering nearly half of T and plate-like, with prolateral EP, a similar arrangement and shape of RTA, but can be distinguished by 1) EP large, at its base half the width of E; 2) dRTA shorter, almost straight (EP developed as small tooth, dRTA longer and curved in P. daxing ). The female of P. langyaensis Zhang, Jäger & Liu , spec. nov. resembles those of P. contraria and P. semiannulata Zhang et al., 2013 ( Zhang et al. 2013a) by: 1) Anterior margins of LL almost parallel to posterior margins; 2) Two posterior margins of LL forming distinct median indentation. It can be distinguished by: 1) Anterior margins of LL slightly bent, slightly far from posterior margins; 2) AB long (anterior margins distinctly bent in P. semiannulata , W-shaped in P. contraria ; AB short in P. semiannulata and P. contraria ).

MALE (LJ01812): Measurements: Medium sized. Body length 10.2–11.4, DS length 5.9, width 5.4, OS length 4.8, width 3.3. Eyes: AME 0.19, ALE 0.27, PME 0.22, PLE 0.25, AME–AME 0.15, AME–ALE 0.08, PME–PME 0.21, PME–PLE 0.29, AME–PME 0.26, ALE–PLE 0.23, CH AME 0.32, CH ALE 0.27. Spination: Pp 131, 101, 2121; Fe I–II 323, III–IV 322; Pa I–III 101, IV 100; Ti I–II 2228, III–IV 2126; Mt I–II 2024, III 3025, IV 3036. Measurements of palps and legs: Pp 6.9 (1.9, 1.0, 1.5, –, 2.5); I 22.2 (6.3, 2.3, 6.1, 5.9, 1.6); II 24.0 (6.5, 2.5, 6.7, 6.2, 2.1); III 18.1 (5.6, 1.4, 4.9, 5.0, 1.2); IV 20.9 (6.1, 1.9, 5.7, 5.4, 1.8). Leg formula: II-I-IV-III. Cheliceral furrow with ca. 25 denticles.

Palp ( Figs 139A–C View FIGURE 139 ): As in diagnosis. C arising from T at 12:00 o’clock position, apically broad. E arising from T at 9:30–10:00 o’clock position. Spermophor with two almost straight parts connected by a right angle, and a distinctly S-shaped part near the basal of E. RTA arising medially from Ti, dRTA finger-shaped, vRTA broad in ventral view, long in retrolateral view.

Colouration ( Figs 141A–B View FIGURE 141 ): DS brown with dark spots and marbled pattern. Fovea and striae distinctly marked. OS dorsally reddish brown with yellow regions at anterior part and lots of yellow dots. OS ventrally reddish brown, margin with thin dark lines, regularly arranged.

FEMALE (LJ01813): Measurements: Medium sized. Body length 13.4–14.5, DS length 6.6, width 5.6, OS length 7.6, width 6.2. Eyes: AME 0.21, ALE 0.29, PME 0.25, PLE 0.31, AME–AME 0.14, AME–ALE 0.09, PME–PME 0.20, PME–PLE 0.31, AME–PME 0.28, ALE–PLE 0.23, CH AME 0.35, CH ALE 0.27. Spination: Pp 131, 101, 2121, 1014; Fe I–II 323, III–IV 322; Pa I–III 101, IV 100; Ti I–II 2228, III–IV 2126; Mt I–II 2024, III 3025, IV 3036. Measurements of palps and legs: Pp 7.1 (2.0, 1.1, 1.5, –, 2.5); I 20.3 (5.7, 2.1, 5.9, 5.0, 1.6); II 23.0 (6.3, 2.5, 6.7, 5.4, 2.1); III 16.1 (4.8, 1.5, 4.4, 4.1, 1.3); IV 19.4 (6.0, 1.3, 4.8, 5.2, 2.1). Leg formula: II-I-IV-III. Cheliceral furrow with ca. 25 denticles.

Epigyne ( Figs 140A–C View FIGURE 140 ): As in diagnosis. EF almost twice as wide as long. AB distinct. Posterior margins of LL curved. S covered by posterior part of LL in dorsal view. FW well developed, its lateral margins parallel to postero-lateral margins of LL.

Colouration ( Figs 141C–D View FIGURE 141 ): As in male, generally darker. DS with at least six scars. If these would be bite marks of the male caused during a coercive mating process as supposed for the genera May Jäger & Krehenwinkel, 2015 (1 out of 4 species; Jäger & Krehenwinkel 2015 from Kalahari) and Thunberga Jäger, 2020 (16 out of 25 species with such scars; from Madagascar and neighbouring islands), it would be the first case in the genus Pseudopoda in particular and in Asian Sparassidae in general.

Distribution. China (Yunnan Province).
