Figs 66–72 View FIGURES 66 – 72 , 137 View FIGURE 137
Type material. Holotype: male (PJ 1898), Dali, Cangshan, hill in front of mountain chain, pine needle litter ( Fig. 134), 2100 m [25°40'59''N, 100°08'53''E, Yunnan Province, China], 14 April 1999, P. Jäger ( SMF).
Paratypes: 1 male (PJ 1899), same data as holotype (IOZ). 1 female (PJ 1909), Dali, Cangshan, hill in front of mountain chain, leaf litter in tree plantation ( Fig. 131) [25°40'59''N, 100°08'53''E, Yunnan Province, China], 4 April 1999, P. Jäger ( SMF).
Other material examined. CHINA: Yunnan Province: 1 subadult female (PJ 2255), Dali, Cangshan, riverside of stream, leaf litter ( Fig. 130), 2200–2400 m [25°40'28''N, 100°08'19''E], 6 April 1999, P. Jäger, by hand ( SMF).
Etymology. The specific name is derived from the type locality, Cangshan (= Cang mountains); adjective.
Diagnosis. Small-sized Heteropodinae. The species can be recognised by the following combination of characters: Males ( Figs 66–68 View FIGURES 66 – 72 ) — 1. Embolus distinctly s-shaped, about same width over its whole length, arising from 7.30-o’clock-position on tegulum, 2. RTA similar to that of P. contraria sp. n. and P. roganda sp. n., but ventral part strongly reduced and without projection. Females ( Figs 71–72 View FIGURES 66 – 72 ) — 1. Anterior margin of lateral lobes v-shaped, 2. Lateral loops of internal duct system extending laterally beyond its first winding.
Description. Male (measurements of holotype first, those for paratype in parentheses): PL 4.4 (3.8), PH 1.6 (1.4), PW 3.7 (3.5), AW 2.3 (2.0), OL 4.3 (not taken), OW 2.9 (not taken). Eyes: AME 0.21 (0.19), ALE 0.31 (0.30), PME 0.28 (0.25), PLE 0.47 (0.35), AME–AME 0.18 (0.17), AME–ALE 0.06 (0.07), PME– PME 0.27 (0.25), PME–PLE 0.32 (0.31), AME–PME 0.33 (0.28), ALE–PLE 0.30 (0.26), CH –AME 0.31 (0.27), CH –ALE 0.29 (0.21).
Leg formula: 2413. Spination: PP 131, 101, 2101; FE I–II 323, III 322, IV 331; PA 001; TI I 202(3)6, II– III 2026, IV 2126; MT I–II 2024, III 3024, IV 3036. Measurements of palps and legs: PP 6.2 (5.7) [1.9, 0.9, 1.2, 2.2], I 15.4 (14.6) [4.0, 1.6, 4.3, 4.0, 1.5], II 17.4 (15.9) [4.8, 1.9, 4.8, 4.2, 1.7], III 14.1(12.3) [4.0, 1.7, 3.7, 3.4, 1.3], IV 15.6 (14.8) [4.2, 1.5, 3.8, 4.5, 1.6].
Palp as in diagnosis. Tip of cymbium with characteristic projection. Tip of embolus pointing prolaterodistally. Sperm duct running almost straight parallel to cymbium's length axis, with s-shaped part at 6-o’clockposition. RTA arising basally from TI ( Figs 66–67 View FIGURES 66 – 72 ).
Colour: Yellowish-brown with dark pattern. DS with bright median band and two longitudinal bands on lateral sides with irregular pattern, being more distinct at its median margins ( Fig. 69 View FIGURES 66 – 72 ). ST ( Fig. 70 View FIGURES 66 – 72 ) and ventral CX with dots, these may be indistinct in CX I. GC and LA without pattern. CC with patches and dots. Appendages with spine-patches and distinctly smaller spots. Prolateral TI and PA additionally with larger patch basally. PA to TA not as bright as FE, more reddish-brown. Dorsal OS darker with three dark longitudinal bands, these surrounding two white areas. Posterior half of OS with dark transversal bands, some fused together, and with bright transversal bands ( Fig. 69 View FIGURES 66 – 72 ); lateral OS with irregular pattern; ventral OS with dots especially in the median part.
Female (measurements of paratype): PL 5.4, PH 1.8, PW 3.7, AW 2.6, OL 5.4, OW 3.1. Eyes: AME 0.22, ALE 0.40, PME 0.26, PLE 0.30, AME–AME 0.23, AME–ALE 0.06, PME–PME 0.31, PME–PLE 0.35, AME–PME 0.30, ALE–PLE 0.32, CH –AME 0.32, CH –ALE 0.31.
Leg formula: 2413. Spination: PP 131, 101, 2121, 1014; FE I–II 323, III 322, IV 331; PA 001; TI I 1026, II–III 2026, IV 2126; MT I 1014, II 2014, III 3024, IV 3036. Measurements of palps and legs: PP 5.2 [1.6, 0.7, 1.1, 1.8], I 13.7 [3.7, 1.9, 3.6, 3.2, 1.3], II 14.3 [4.1, 2.1, 3.5, 3.3, 1.3], III 12.3 [3.6, 1.8, 2.8, 2.9, 1.2], IV 14.1 [4.1, 1.6, 3.4, 3.8, 1.2].
Copulatory organ as in diagnosis. Epigynal field only slightly wider than long, with small anterior bands and trilobate anterior margin. Anterior margins of lateral lobes extending clearly into anterior half of epigyne ( Fig. 71 View FIGURES 66 – 72 ). Lateral loops of internal duct system appearing as dark patches in the centre of lateral lobes. First winding only with lateral rim ( Fig. 72 View FIGURES 66 – 72 ), i.e. not with an additional inner (= median) rim as in other Pseudopoda spp. described in this paper. Fertilisation ducts forming with dorsal membranous part equilateral triangle ( Fig. 72 View FIGURES 66 – 72 ).
Colour: As in male, but dorsal OS with thin white transversal line in posterior half and ventral OS with only two converging lines of single dots. Pattern on appendages more distinct, especially additional prolateral patches on PA and TI larger and present also on retrolateral side in leg IV. All PA with retrolateral patch.
Distribution. Only known from the type locality (12 in Fig. 137 View FIGURE 137 ).
Relationships. See P. roganda sp. n. Females cannot be associated unambiguously with any other species.
