Figs 20 , 21 , 55G , 58 Types. Holotype : ♂ (IZCAS), China, Yunnan Province, Yuxi Town, Yuanjiang County, Yangchajiexiang Nature Reserves, Nanxi Region, 23°9.6320'N , 101°45.5640'E , elevation ca 2144 m, 4.VI.2015, Y. Li and Z. Chen leg. Paratype : 1♀ (IZCAS), same data as holotype. Etymology. The species name is a noun in apposition derived from the Chinese pinyin "maochong" (caterpillar) and refers to the structure of spermathecae which resemble a caterpillar in lateral view. Diagnosis. Males of L. maochong sp. nov. resemble L. shanzi sp. nov. but can be distinguished by a pair of divided conductors (Fig. 21B ) (i.e. - consisting of two components) (vs. a slightly twisted undivided conductor (Fig. 23B )), an absence of a laminar apophysis adjacent to embolus (vs. presence of a laminar apophysis adjacent to embolus), embolus two times longer than tegulum (vs. embolus of similar length to tegulum), presence of two dorsal apophyses anteriorly on tibia (Fig. 21D ) (vs. the presence of two retrolateral tibial apophyses anteriorly (Fig. 23C )); females can be recognized by having more coils of the spermathecae and by having a pair of lateral, spherical structures connected via the duct system to the posterior ends of the spermathecae (Fig. 20A ) (vs. an absence of posterior extensions of the spermathecae), external genitalia a dark purplish, rectangular patch (Fig. 20B ) (vs. fan-shaped external genitalia (Fig. 22B )), dorsum with oblique lateral dark brown stripes (Fig. 20D ) (vs. dark brown lateral bands with parallel lines on dorsum (Fig. 22D )). Figure 20. Leclercera maochong 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. Abbreviations: SP = spermatheca, SS = spherical structure. Description. Male (Holotype). Total length 2.58; carapace 0.88 long, 1.20 wide; abdomen 1.70 long, 0.80 wide. Carapace round and brown, with three dark brown longitudinal bands, median band two times wider than lateral band (Fig. 20C ). Chelicerae brown (Fig. 55G ). Clypeus with dark brown band medially. Endites dark brown, light brown basally. Labium dark brown. Sternum dark brown with vertically thin median light brown band. Abdomen elongated, dorsum with pairs of dark brown spots, posterior with dark brown horizontal stripes, antero-ventrally with a pair of ovoid brown patches followed by rectangular dark brown patch, posterior with complicated dark brown pattern. Legs uniformly brown; measurements: I-IV missing. Palp (Fig. 21A-D ): femur slender, four times longer than patella; patella not swollen; tibia swollen, 1.5 times shorter and 3 times wider than femur, with two dorsal apophyses anteriorly (apophyses almost as long as cymbium); cymbium three times shorter than femur, dark brown distally; bulb brown, pyriform, with conductor and embolus arising distally; conductor comprises two components, basally and distally merged with embolus; embolus elongated and sheet-like, slightly twisted, two times longer than tegulum (Fig. 21B ). Female (Paratype). General features and coloration similar to those of male (Fig. 20D, E ). Measurements: total length 2.66; carapace 0.78 long, 0.94 wide; abdomen 1.88 long, 1.25 wide. Leg measurements: I 8.84 (2.40, 0.31, 2.88, 2.00, 1.25), II 7.06 (2.00, 0.31, 2.03, 1.72, 1.00), III missing, IV 8.17 (2.40, 0.31, 2.34, 2.03, 1.09). Epigastric area (Fig. 20B ): rectangular dark brown patch anteriorly, followed by brown crescent-shaped slit posteriorly. Endogyne (Fig. 20A ): spermathecae resembles a crawling caterpillar in lateral view, with pointed ends, connected posteriorly to a pair of lateral spherical bodies by a duct system double-looped like a shallow "W" . Distribution. Known only from the type locality (Fig. 58 ). Figure 21. Leclercera maochong sp. nov. A Bulb, ventral view B bulb, ventral view C palp, prolateral view D palp, retrolateral view.
