Jerzego qiuhangi

Male (Fig. 1A–C, Fig. 3A, B and D–F). Total length 5.25. Carapace 2.44 long, 1.69 wide. Abdomen 2.75 long, 1.41 wide. Eye sizes and inter distances: AME 0.42, ALE 0.21, PLE 0.19, AERW 1.16, PERW 1.25, EFL 0.98. Legs: I 4.06 (1.38, 0.85, 0.80, 0.53, 0.50), II 3.41 (1.00, 0.70, 0.75, 0.48, 0.48), III 3.11 (0.95, 0.55, 0.60, 0.63, 0.38), IV 4.14 (1.20, 0.73, 0.98, 0.85, 0.38). Carapace dark, flat, bearing short white scales bilaterally and posteriorly; fovea longitudinal. Chelicerae each with three promarginal and retromarginal teeth. Endites elongated, with pale disto-inner areas. Labium almost as long as wide. Sternum about 1.5 times longer than wide, covered with dark thin setae and with rather pointed posterior end. Legs yellowish-brown to dark, covered with sparse white scales, with enlarged femora and tibiae Ⅰ and bearing dense, long setae ventrally on patellae and tibiae Ⅰ. Abdomen elongated, dorsum dark, covered with sparse white scales anteriorly, with sub-fusiform scutum on median line of anterior 1/3, followed by pair of dark grey, elongate-oval patches and pair of inclined white stripes of scales on posterolateral side; venter with four dotted lines extending from epigastric furrow to terminus.

Palp (Fig. 1A–C): tibia almost as long as wide in retrolateral view, with broad retrolateral apophysis slightly more than half its width; cymbium about 1.5 times longer than wide; bulb swollen medio-posteriorly, with well-developed posterior lobe extending towards postero-prolateral side; embolus straight, originating from anteroprolateral portion of bulb, with inner membranous portion and rather pointed tip.

Female (Fig. 2A–D and Fig. 3C). Total length 5.93. Carapace 2.71 long, 1.82 wide. Abdomen 3.11 long 1.61 wide. Eye sizes and inter distances: AME 0.43, ALE 0.22, PLE 0.20, AERW 1.32, PERW 1.36, EFL 1.14. Legs: I 4.02 (1.33, 0.73, 0.88, 0.58, 0.50), II 3.68 (1.10, 0.75, 0.85, 0.53, 0.45), III 3.24 (0.98, 0.53, 0.65, 0.65, 0.43), IV 4.54 (1.33, 0.78, 1.05, 0.95, 0.43). Habitus similar to that of male, except without dorsal abdominal scutum.

Epigyne (Fig. 2A–D): almost as long as wide, with well-developed, oval atrium with arc-shaped anterior ridge; copulatory openings elongate-oval, separated from each other by about 2/3 atrial width; copulatory ducts posteriorly extending with slight curves at proximal, medio-proximally divided into much thinner, straight, bar-shaped dorsal branch and irregular curved ventral branch and both branches fused at position of posterior 1/3, remainder portions broadened and curved into nearly C-shape in lateral view; accessory glands mediolaterally located on proximal 1/3 of copulatory ducts, curved about 70° at beginning and then running anteriorly; spermathecae nearly spherical, touching each other; fertilisation ducts originating from anterior portions of spermathecae.

The male of Jerzego qiuhangi sp. nov. resembles that of J. corticicola Maddison 2014 in the general shape of the palp, but can be easily distinguished by the embolus, which is about half the bulb length and has an inner membranous portion (Fig. 1B) vs. about 1/4 the bulb length and lacks similar membranous portion in J. corticicola (Maddison and Piascik (2014): fig. 2). The female of this new species resembles that of J. bipartitus (Simon, 1903) in having the similar habitus pattern and epigyne, but can be easily distinguished by the lack of epigynal septum (Fig. 2A) vs. present in J. bipartitus (Wanless (1981): fig. 12F). The species also somewhat resembles that of J. sunillimaye Sanap, Caleb & Joglekar, 2019 in having rather consistent dorsal patterns of the abdomen, but differs by the straight embolus originating from the anteroporlateral portion of tegulum and has a pointed tip and by the lack of median septum (Fig. 1B and Fig. 2A) vs. twisted embolus originating from the central portion of tegulum and has a blunt tip and the presence of median septum in J. sunillimaye (Sanap et al. (2019): figs 5, 7, 9, 16 and 18).

The specific name is a patronym of the collector; noun (name) in genitive case.
