description: Pseudopoda saetosa sp. n.
Figs 16–23, 137
Type material: Holotype: male holotype (PJ 1928), Nujiang Prefecture, Gaoligong Shan, Gongshan County, Danzhu He drainage, 15.7–16.0 air km SW of Gongshan, 2900–3100 m [27.627°N, 98.592°E to 27.622°N 98.587°E, Yunnan Province, China], 30 June – 5 July 2000, H.M. Yan, D. Kavanaugh, C.E. Griswold, H.B. Liang, D. Ubick & D.Z. Dong (HNU).
Paratypes: 2 males, 2 females (PJ 1926–1927, PJ 1929–30), same data as holotype (1 male, 1 female HNU; 1 male, 1 female CAS).
Etymology. The specific name is derived from the Latin word ‘saetosus, -a, -um’, meaning ‘hirsute’, referring to the setae on the dorsal margin of the RTA; adjective.
Diagnosis. Small-sized Heteropodinae. Species may be recognised by the following combination of characters: Males (Figs 16–19) — 1. Embolus sickle-shaped, bent at a right angle (ventral view), 2. RTA with distinct setae on its dorsal margin (retrolateral view). Females (Figs 20–23) — With similar copulatory organ as P. contentio sp. n., but differs in the following characters: 1. Anterior margins of lateral lobes straight, running more transversally (slightly bent and more diagonal in P. contentio sp. n.), 2. Internal duct system visible through cuticle in a ventral view as large rather circular patches (elongated patches in P. c o n t e n t i o sp. n.), 3. Posterior end of first winding of internal duct system hidden by a internal bulge (freely visible in P. contentio sp. n.), 4. Margin of first winding narrow (wider in P. contentio sp. n.).
Description. Male (measurements of holotype first, those for paratypes in parentheses): PL 3.7 (3.6– 3.7), PH 1.4 (1.3–1.7), PW 3.3 (3.1), AW 1.9 (1.8), OL 4.3 (3.8–4.1), OW 2.8 (2.5–2.7). Eyes: AME 0.19 (0.17), ALE 0.31 (0.25–0.27), PME 0.20 (0.17–0.18), PLE 0.27 (0.26), AME–AME 0.13 (0.13–0.16), AME– ALE 0.04 (0.04–0.05), PME–PME 0.24 (0.21–0.26), PME–PLE 0.29 (0.27–0.28), AME–PME 0.29 (0.24), ALE–PLE 0.22 (0.22–0.23), CH –AME 0.22 (0.23–0.25), CH –ALE 0.19 (0.20–0.23).
Leg formula: 2143. Spination: PP 131, 101, 2101; FE I–II 323, III 322, IV 331; PA 001; TI 2026, MT I–II 2024, III 3034, IV 3036. Measurements of palps and legs: PP 5.6 (5.3) [1.9,0.9,1.0,1.8], I 18.3 (17.0–17.5) [4.6, 2.0, 5.1, 4.9, 1.7], II 19.9 (18.5) [5.2, 2.1, 5.5, 4.9, 1.6], III 16.7 (15.3–15.6) [4.5, 1.6, 4.7, 4.3, 1.6], IV 17.9 (16.8–17.1) [4.7, 1.6, 4.8, 5.1, 1.7].
Palp as in diagnosis. Retrolateral margin of cymbium almost straight (ventral view, Fig. 17), giving a somewhat triangular impression of cymbium. Embolus arising from a 10-o’clock-position on the tegulum, short and widened, its tip pointing distally. Sperm duct broad, running submarginally along retrolateral margin of tegulum (Fig. 17), bent in an acute angle at tegular bulge (prolateral view; Fig. 16). RTA arising basally from TI (Fig. 17). RTA similar to that of Pseudopoda gongschana sp. n., but having interspace between ventral and dorsal part larger and ovoid, and having dorsal finger-shaped part more slender. Dorsal RTA with 4–5 hairs on dorsal side of the apophysis. Setae on RTA as long as dorsal spine of TI (retrolateral view; Fig. 18).
Colour: Yellowish-brown. DS and ST without distinct pattern. Some darker brown lines along the striae. CC yellowish-brown as DS. OS brown, brighter in anterior half, darker at posterior part. Legs uniformly yellowish-brown with some darker spine-patches. Spinnerets yellowish-brown but brighter than rest of the body.
Female (measurements of paratypes): PL 3.7–4.0, PH 1.4–1.7, PW 3.2–3.6, AW 2.0–2.2, OL 4.8–5.3, OW 3.1–3.4. Eyes: AME 0.14–0.18, ALE 0.26–0.29, PME 0.16–0.22, PLE 0.26–0.28, AME–AME 0.21– 0.26, AME–ALE 0.06–0.07, PME–PME 0.30, PME–PLE 0.33–0.35, AME–PME 0.25–0.28, ALE–PLE 0.23– 0.26, CH –AME 0.33–0.41, CH –ALE 0.26–0.32.
Leg formula: 2413. Spination: PP 131, 101, 2121, 1014; FE I–II 323, III 322(3), IV 331; PA 001; TI 2026; MT I–II 2024, III 3034, IV 3036. Measurement of palps and legs: PP 4.5–5.5 [1.5, 1.0, 1.3, 1.7], I 11.1–13.3 [3.7, 2.0, 5.1, 4.9, 1.7], II 13.4–15.2 [5.2, 2.1, 5.5, 5.3, 1.8], III 10.4–12.6 [3.7, 1.6, 3.0, 3.1, 1.2], IV 11.17– 13.98 [3.9, 1.5, 3.3, 3.9, 1.3].
Copulatory organ as in diagnosis. Epigynal field wider than long, with short or indistinct anterior bands. Lateral lobes touching each other along a distance at the median line. Posterior margins irregularly rounded (Figs 20, 22). Space between fertilisation ducts and first winding larger than width of first winding (Figs 21, 23).
Colour: As in male, but generally darker.
Variation. One female paratype (PJ 1926) with posterior OS having a broad white transversal band.
Distribution. Only known from the type locality (5 in Fig. 137).
Relationships. Embolus conformation in males is very similar to that of P. platembola and Pseudopoda sp. cf. platembola (Jäger 2001: figs 35f-i; open square in Fig. 137). P. s a e t o s a sp. n. is distinguished by the RTA having its ventral part more strongly pronounced in comparison with its dorsal part. Additionally the transverse basal branch of the embolus is shorter in P. saetosa sp. n.
