Type material. Holotype: male (PJ 1907), Dali, riverside of stream, leaf litter and gravel ( Fig. 130), 2200 m [25°40'28''N, 100°08'19''E, Yunnan Province, China], 5 April 1999, P. Jäger ( SMF).

Paratypes: 1 female (PJ 1910), Dali, Cang Shan, near monastery, moulting 6 a.m. on stalk of grass ( Fig. 132), 2500 m [25°41'47"N, 100°06'47"E, Yunnan Province, China], 8 April 1999, P. Jäger ( SMF). 2 males (PJ 1911–1912), 3 females (PJ 1913–1915), Dali, Cang Shan, gorge, under stones of gravel bank on riverside of stream, 2300 m, [25°40'28''N, 100°08'19''E, Yunnan Province, China], 16 April 1999, P. Jäger (1 male, 2 females SMF; 1 male, 1 female IOZ). 2 females (PJ 1916–1917), Dali, under stones of gravel bank on riverside of stream, gorge, 2200 m [25°40'28''N, 100°08'19''E, Yunnan Province, China], 15 April 1999, W. Schawaller (1 female SMF; 1 female IOZ).

Other material examined. 1 subadult male (PJ 2237), same data as holotype ( SMF) (note: structures of copulatory organs of subadult specimens were recognisable after removing the penultimate moult of the palp. These structures and colouration point clearly to conspecifity with the holotype).

Etymology. The specific name refers to the type locality, the town Dali; adjective.

Diagnosis. Small-sized Heteropodinae. The species can be recognised by the following combination of characters: Males ( Figs 79–81, 84 View FIGURES 79 – 90 ) — 1. Tegulum large, extending beyond retrolateral margin of cymbium, 2. Embolus broad, sickle-shaped, with small projection on prolateral margin, 3. Both dorsal and ventral part of RTA, well developed, broad; tip of dorsal RTA with two teeth. Females ( Figs 86–89 View FIGURES 79 – 90 ) — 1. Posterior part of lateral lobes with distinct lateral projections, 2. Internal duct system with loops, these extending laterally beyond first winding in dorsal view.

Measurements of palps and legs: PP 7.1 (5.9–6.3) [2.2, 1.0, 1.3, 2.6], I 20,1 (17.9–19.7) [5.4, 2.1, 5.5, 5.2, 1.9], II 21.3 (18.9–20.7) [5.8, 2.0, 6.1, 5.4, 2.0], III 17.0 (16.0–16.2) [4.8, 1.6, 4.7, 4.1, 1.8], IV 18.3 (16.6–17.5) [5.1, 1.6, 5.1, 5.0, 1.5].

Palp as in diagnosis. Cymbium with large retrolateral bulge. Tegulum occupying whole alveolus. Embolus arising from 10.30-o’clock-position on tegulum, its tip pointing prolaterally. RTA arising basally from TI ( Figs 80, 84 View FIGURES 79 – 90 ), its broad ventral part with its two margins oriented to each other at a right angle (retrolateral view, Fig. 81 View FIGURES 79 – 90 ), dorsal RTA bent, broad.

Colour: DS yellowish-brown with irregular pattern consisting of dark spots and small patches of dark hairs. CX, LA and GC pale yellowish-brown without pattern, ST with few small spots ( Fig. 82 View FIGURES 79 – 90 ), CC with longitudinal rows of patches. Other appendages as DS, with small brown spots, spine patches ( Fig. 83 View FIGURES 79 – 90 ) and two patches prolaterally on proximal TI. Dorsal OS with dark heart patch, chevron-like markings behind and a white transversal line in posterior half consisting of white short hairs; OS laterally with irregular pattern; ventral OS brighter, with pair of spots in front of epigastric furrow and V-shaped pattern consisting of distinct round spots ( Fig. 85 View FIGURES 79 – 90 ).

Leg formula: 2143. Spination: PP 131, 101, 2121, 101(0)4; FE I–II 323, III 32 (3)2(1–3), IV 331; PA 001; TI I–II 3136 (2126), III–IV 2126; MT I–II 2024, III 3(2)0(1)24, IV 3036. Measurements of palps and legs: PP 5.0–6.1 [1.7, 0.8, 1.3, 1.8], I 14.0–16.0 [4.3, 1.8, 4.6, 3.7, 1.6], II 15.3–17.6 [5.0, 2.1, 4.8, 3.8, 1.6], III 11.9– 13.4 [4.0, 1.3, 3.5, 3.1, 1.2], IV 13.6–15.3 [4.6, 1.5, 3.8, 3.8, 1.4].

Copulatory organ as in diagnosis. Epigynal field wider than long, with very short anterior bands or without such bands. Anterior margins of lateral lobes bent posteriorly at their lateral ends. Lateral loops of internal duct system appearing as transversal patches close to anterior margins of lateral lobes in ventral view ( Figs 86–87 View FIGURES 79 – 90 ). Wrinkles present in anterior half of epigyne in ventral view and between first windings of internal duct system in dorsal view.

Colour: Generally as in male but less distinct (e.g., ventral OS: Fig. 90 View FIGURES 79 – 90 ).

Variation. Spination of FE III varying from 321 and 322 to 333. The dark posterior half of the dorsal OS in the subadult male (PJ 2237) exhibits a large white patch.

Distribution. Only known from the type locality (12 in Fig. 137 View FIGURE 137 ).
