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 “máochóng” (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 View Figure 21 ) (i.e. - consisting of two components) (vs. a slightly twisted undivided conductor (Fig. 23B View Figure 23 )), 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 View Figure 21 ) (vs. the presence of two retrolateral tibial apophyses anteriorly (Fig. 23C View Figure 23 )); 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 View Figure 20 ) (vs. an absence of posterior extensions of the spermathecae), external genitalia a dark purplish, rectangular patch (Fig. 20B View Figure 20 ) (vs. fan-shaped external genitalia (Fig. 22B View Figure 22 )), dorsum with oblique lateral dark brown stripes (Fig. 20D View Figure 20 ) (vs. dark brown lateral bands with parallel lines on dorsum (Fig. 22D View Figure 22 )).

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 View Figure 20 ). Chelicerae brown (Fig. 55G View Figure 55 ). 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 View Figure 21 ): 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 View Figure 21 ).

Female (Paratype). General features and coloration similar to those of male (Fig. 20D, E View Figure 20 ). 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 View Figure 20 ): rectangular dark brown patch anteriorly, followed by brown crescent-shaped slit posteriorly. Endogyne (Fig. 20A View Figure 20 ): 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”.
