Pseudopoda acutiformis Zhang, Jäger & Liu , spec. nov. Figs 4–5 View FIGURE 4 View FIGURE 5 , Map 5 View MAP 5

Type material. CHINA, Sichuan Province: Holotype male from Ya’an City, Baoxing County, Fengtongzhai National Nature Reserve , 30.57°N, 102.88°E, 1682 m, 5 May 2016 , Y. Zhong leg. ( CBEE, LJ2197 ) GoogleMaps . Paratype: 1 male, with same data as for holotype. ( CBEE, LJ2199 ) GoogleMaps .

Etymology. The specific name is derived from the Latin adjective acutiformis , - is, - e, meaning “spiky”, referring to the acute and thin apical tip of the E; adjective.

Diagnosis. The male of P. acutiformis Zhang, Jäger & Liu , spec. nov. is similar to that of P. triangula Zhang et al., 2013 ( Zhang et al. 2013a) in having a very large EP and a flagelliform E. It can be distinguished by the RTA broader (i.e. almost as broad as tibia in retrolateral view) and longer (i.e. less than half the width of tibia in retrolateral view and distinctly shorter in P. triangula ).

MALE (LJ2197): Measurements: Small sized. Body length 7.8–8.3, DS length 4.2, width 3.6, OS length 4.1, width 2.6. Eyes: AME 0.17, ALE 0.25, PME 0.19, PLE 0.22, AME–AME 0.20, AME–ALE 0.15, PME–PME 0.24, PME–PLE 0.36, AME–PME 0.31, ALE–PLE 0.29, CH AME 0.41, CH ALE 0.33. Spination: Pp 131, 101, 2121; Fe I–II 323, III 322, IV 331; Pa I–IV 100; Ti I–III 2026, IV 2126; Mt I–II 1014, III 2026, IV 3036. Measurements of palps and legs: Pp 7.2 (2.1, 1.0, 1.6, –, 2.5); I 23.6 (7.6, 1.8, 6.7, 6.0, 1.5); II 27.6 (7.8, 2.6, 8.1, 7.0, 2.1); III 19.2 (5.7, 1.6, 5.5, 5.1, 1.3); IV 22.6 (7.2, 1.1, 6.0, 6.6, 1.7). Leg formula: II-I-IV-III. Cheliceral furrow with ca. 15 denticles.

Palp ( Figs 4A–C View FIGURE 4 ): C arising from T at 11:30–12:00 o’clock position. E arising from T at 9:00–9:30 o’clock position, broad in its middle part, with thin apical part prolaterad. EP very prominent. Spermophor visible submarginally on retrolateral T in ventral view. RTA arising medially from Ti, with ventral bulge, seen as rectangular incision in retrolateral view; distal tip with tiny humps.

Colouration ( Figs 5A–B View FIGURE 5 ): DS yellow with strong marbled pattern with black spots and lines, fovea and striae distinctly marked, chelicerae, sternum and ventral coxae with distinct patches and spots. OS dorsally reddish brown, with two white longitudinal areas lateral from the heart region in anterior half, with yellow transversal patch in posterior half. OS ventrally yellow, with lots of reddish-brown spots, irregularly arranged, some fused to an anteriorly diverging trapezoid.

FEMALE: Unknown.

Distribution. China (Sichuan Province).
