Leclercera xiangbabang sp. nov. Figs 9, 10, 55F, 58

Types.

Holotype: ♂ (IZCAS), Thailand, Kanchanaburi Province, Sai Yok District, Wang Krachae Subdistrict, Cave without name, 14°12.1820'N, 99°01.4161'E, elevation ca 342 m, 01.XI.2014, H. Zhao, Y. Li, Z. Chen leg. Paratype: 1♀ (IZCAS), same data as holotype.

Etymology.

The species name is a noun in apposition derived from the Chinese pinyin “xiàngbábàng” (geoduck) and refers to the entire structure of the bulb which resembles the appearance of a Pacific geoduck bivalve.

Diagnosis.

Males of L. xiangbabang sp. nov. resemble L. jianzuiyu sp. nov. by having a spatulate bulb and a retrolateral apophysis on the tibia but can be distinguished by a rather bulging bulb and a wider embolus (Fig. 10B) (vs. a rather slender bulb and thin embolus (Fig. 12B)), a retrolateral apophysis on tibia, half the length of the tegulum (Fig. 10D) (vs. retrolateral apophysis on tibia equal in length to tegulum (Fig. 12C)); females can be differentiated by the elongated tubular spermathecae (Fig. 9A) (vs. rounded spermathecae (Fig. 11A)).

Description.

Male (Holotype). Total length 3.18; carapace 0.80 long, 0.88 wide; abdomen 2.38 long, 0.80 wide. Carapace round and brown, with three longitudinal dark brown bands, median band two times wider than lateral band (Fig. 9C). Chelicerae brown (Fig. 55F). Clypeus dark brown medially, light brown laterally. Endites dark brown, light brown basally. Labium dark brown. Sternum dark brown, delimiting a short, light brown band medially. Abdomen elongated, anterior and posterior edge dark brown, with scattered dark and light brown patterns, antero-ventrally with dark brown circular patches laterally, with complex dark and light brown patterns posteriorly. Legs uniformly brown; measurements: I 12.75 (4.00, 0.25, 3.75, 3.00, 1.75), II 9.06 (2.75, 0.31, 2.40, 2.60, 1.00), III 6.51 (1.88, 0.25, 1.88, 1.75, 0.75), IV 9.51 (3.20, 0.31, 2.40, 2.60, 1.00). Palp (Fig. 10A-D): femur slender, four times longer than patella; patella not swollen; tibia swollen, 1.5 times shorter and two times wider than femur, with retrolateral apophysis anteriorly bearing a spine, about half the length of tegulum, spine and apophysis almost equal in length; cymbium dark brown, three times shorter than femur; bulb bulging, spatulate, brown, with embolus arising distally; embolus elongated, with blunt tip, as long as tegulum, tegulum three times wider than embolus (Fig. 10B).

Female (Paratype). General features and coloration similar to those of male (Fig. 9D, E). Measurements: total length 2.26; carapace 0.63 long, 0.75 wide; abdomen 1.63 long, 1.13 wide. Leg measurements: I missing, II 7.51 (2.25, 0.25, 2.13, 2.00, 0.88), III 7.81 (2.25, 0.25, 2.34, 2.03, 0.94), IV 5.30 (1.60, 0.25, 1.50, 1.25, 0.70). Epigastric area (Fig. 9B): dark brown slit that slightly curves posteriorly. Endogyne (Fig. 9A): elongated tubular spermathecae, slightly slanting, length of a spermatheca is 2.5 times its width.
