Etymology. The specific epithet is referring to the type locality (Gongshan); adjective.

Diagnosis. Small- to medium-sized Heteropodinae. The species may be recognised by the following combination of characters: Males ( Figs 10–12 View Figure ) — 1. Embolus short and slightly bent, with triangular indentation close to tip (ventral view), 2. Interspace between dorsal and ventral RTA about the width of dorsal RTA (retrolateral view). Females ( Figs 13–15 View Figure ) — 1. Anterior margins of lateral epigynal lobes semicircular, 2. Internal duct system visible through cuticle in ventral view as large circular patches in centre of lateral lobes. 3. Margins of first winding of internal duct system undulated.

Eyes: AME 0.22 (0.22–0.26), ALE 0.34 (0.32–0.33), PME 0.26 (0.22–0.26), PLE 0.34 (0.27–0.33), AME–AME 0.17 (0.17–0.20), AME–ALE 0.09 (0.04–0.08), PME–PME 0.32 (0.26–0.33), PME–PLE 0.33 (0.31–0.33), AME– PME 0.31 (0.22–0.30), ALE–PLE 0.25 (0.23–0.27), CH –AME 0.37 (0.33–0.49), CH –ALE 0.33 (0.28–0.43). Leg formula: 2143. Spination: PP 131, 101, 2101; FE I–II 323, III 322 (323; n= 2), IV 331; PA I–II 101, III 101 (001), IV 000; TI I–II 2226, III 2226 – 2026, IV 2126; MT I–II 2024, III 3024, IV 3036. Measurements of palps and legs: PP 8.6 (7.7 –9.0) [2.8, 1.3, 1.6, 2.9], I 29.5 (29.3–31.1) [7.5, 2.6, 8.2, 8.6,2.6], II 32.3 (31.7– 33.2) [8.3, 2.7, 9.1, 9.4, 2.8], III 26.9 (25.9–27.6) [7.2, 2.3, 7.6, 7.5, 2.3], IV 28.7 (27.8–29.7) [6.6, 2.5, 8.3, 8.6, 2.7].

Palp as in diagnosis. Cymbium with distinct retrolateral bulge. Embolus originating from 9 -o’clock-position on the tegulum ( Fig. 11 View Figure ), slightly sickle-shaped (prolateral view, Fig. 10 View Figure ). Sperm duct running semi-marginally along retrolateral side of tegulum ( Fig. 11 View Figure ), narrow at prolateral side and s-shaped on tegular bulge (prolateral view, Fig. 10 View Figure ).

Colour: DS yellowish-brown, with brown markings along the fovea and striae. CC reddish-brown and darker than rest of body. ST without distinct pattern. Dorsal OS dark brown with irregular darker patch, in posterior half with white transversal band. Legs yellowish-brown, bright at basal segments, distal segments darker.

Female (measurements of paratypes): PL 5.3–6.2, PH 2.2–2.5, PW 4.0– 5.1, AW 2.9–3.2, OL 7.1 –10.0, OW 4.6 –8.0. Eyes: AME 0.23–0.28, ALE 0.35–0.42, PME 0.26–0.28, PLE 0.31–0.38, AME–AME 0.22– 0.30, AME–ALE 0.04–0.08, PME–PME 0.33–0.41, PME–PLE 0.40–0.44, AME–PME 0.31–0.36, ALE–PLE 0.26–0.31, CH –AME 0.42–0.75, CH –ALE 0.35–0.69.

Leg formula: 2143. Spination: PP 131, 101, 2121, 1014; FE I–III 323, IV 331; PA I–III 0 0 1 (101), IV 000; TI I–II 2226 (2126), III–IV 2226 (2026); MT I–II 2024, III 3024, IV 3036. Measurements of palps and legs: PP 7.6–8.3 [2.3, 1.2, 1.6, 2.5], I 21.1–23.9 [5.9, 2.7, 6.4, 6.9, 2.0], II 22.0–25.0 [6.8, 2.9, 6.8, 6.4, 2.1], III 18.4–20.9 [5.9, 2.3, 5.5, 5.3, 1.9], IV 20.9–23.2 [6.2, 2.4, 6.1, 6.4, 2.1].

Copulatory organ as in diagnosis. Epigynal field wider than long. Epigyne with anterior margins of lateral lobes distinctly bent posteriolaterally. Lateral lobes touching each other only slightly, their posterior margins with median indentation. Dorsal part of lateral lobes extending in anterior half of vulva ( Figs 13–15 View Figure ).

Colour: As in male, but generally darker.

Variation. Variable leg spination in PA I–III (101 in n= 18, 0 0 1 in n= 14) and TI (2226 in n=16, 2126 in n=15, 2026 in n= 1).

Distribution. Known from two different localities in the Gongshan mountains in Yunnan Province (localities 4, 6 in Fig. 137 View Figure ).

Relationships. Males are clearly similar to those of the two previous species. According to the shape of the anterior margins of lateral lobes as well as the size and shape of the globular structures of the internal duct system (ventral view) females are similar to that one recorded from N-Myanmar, illustrated by Jäger (2001: figs 35 j–l). The latter specimen could not be assigned unambiguously to one of the two males collected with it ( P. platembola Jäger, 2001  ; Pseudopoda  sp. cf. platembola  ).
