Leclercera jiazhongensis sp. nov., male holotype and female paratype. A Endogyne, dorsal view B female epigastric area, ventral view C male habitus, dorsal view D female habitus, dorsal view E female habitus, ventral view. Abbreviation: SP = spermatheca. Diagnosis. Males of L. jiazhongensis sp. nov. resemble L. aniensis sp. nov. but can be distinguished by the presence of a prolateral apophysis bearing a spine on the tibia (Fig. 54D ) (vs. the presence of two retrolateral apophyses, each bearing a spine, on the tibia, where the anterior apophysis is branched and resembles a claw (Fig. 42D )), cymbium similar in length to tibia (vs. cymbium about three times shorter than the tibia), tibia swollen, resembles "D" shape (vs. tibia swollen, resembles isosceles triangle), bulb rather slender and elongated (Fig. 54B ) (vs. bulb rather plump and short (Fig. 42B )), and the presence of one laminar apophysis (vs. the presence of three laminar apophyses); females can be distinguished by a pair of long, wavy, stalked spermathecae (Fig. 53A ) (vs. a pair of short and upturned stalked spermathecae (Fig. 41A )). Description. Male (Holotype). Total length 3.44; carapace 0.94 long, 1.13 wide; abdomen 2.50 long, 1.13 wide. Carapace round and brown, with three dark brown longitudinal bands, median band four times wider than lateral band (Fig. 53C ). Chelicerae brown (Fig. 57G ). Clypeus brown, dark brown medially. Endites dark brown, light brown basally. Labium dark brown. Sternum with dark brown stripes. Abdomen elongated, dorsum with three pairs of dark brown spots laterally, posterior with dark brown horizontal stripes, antero-ventrally with a pair of kidney-shaped dark brown spots laterally, followed by elliptical dark brown region, posterior dark brown, delimiting vertical light brown lines laterally. Legs uniformly brown; measurements: I 10.84 (2.24, 0.40, 3.60, 3.00, 1.60), II 10.60 (3.00, 0.40, 3.20, 2.75, 1.25), III 7.49 (2.20, 0.40, 2.00. 1.80, 1.09), IV 10.55 (3.00, 0.40, 3.00, 2.75, 1.40). Palp (Fig. 54A-D ): femur slender, five times longer than patella; patella not swollen; tibia swollen forming a "D" shape, 2 times shorter and only slightly wider than femur, with a prolateral apophysis bearing spine anteriorly, spine two times shorter than apophysis (Fig. 54D ); cymbium two times shorter than femur, similar in length but two times narrower than tibia; bulb brown, pyriform, with embolus, laminar apophysis, and conductor arise distally; embolus black and slender, widest between laminar apophysis and conductor, similar in length to conductor and two times longer than laminar apophysis; laminar apophysis appears to be shortest, basally connected to embolus; conductor alongside embolus, and similar in width to embolus (Fig. 54B ). Female (Paratype). General features and coloration similar to those ofmale (Fig. 53D, E ). Measurements: total length 3.00; carapace 1.00 long, 1.00 wide; abdomen 2.00 long, 1.50 wide. Leg measurements: I 10.51 (2.80, 0.31, 3.20, 2.60, 1.60), II 9.35 (2.75, 0.40, 2.75, 2.25, 1.20), III 6.46 (1.75, 0.31, 1.80, 1.60, 1.00), IV 9.32 (2.60, 0.31, 2.66, 2.34, 1.41). Epigastric area (Fig. 53B ): semi-circular dark brown patch. Endogyne (Fig. 53A ): pair of lengthy, stalked spermathecae with anterior wavy horizontal part and twisted vertical posterior part, both parts with rounded tips, posterior ends with a pair of elliptical bodies. Distribution. Known only from the type locality (Fig. 58 ). Figure 54. Leclercera jiazhongensis sp. nov. A Palp, ventral view B bulb, ventral view C palp, prolateral view D palp, retrolateral view.
