Type material.
Holotype: ♂ (IZCAS-Ar44458), China, Yunnan: Menglun Town: Xishuangbanna Nature Reserve, 21.9611°N, 101.1982°E, ca 790 m, 16-24.2006, Guo Zheng leg. Paratypes: 1♀ (IZCAS-Ar44459), same data as holotype; 11♀ (IZCAS-Ar44460-Ar44470), China, Yunnan: Menglun Town: Xishuangbanna Botanical Garden, 21.8970°N, 101.2845°E, ca 613 m, 1-15.II.2007, Guo Zheng leg.
Diagnosis.
The new species similar to S. evertsi Ovtsharenko, Levy & Platnick, 1994 by the male with a retrolateral tibial hood (Fig. 16B View Figure 16 ) and lake of retrolateral tibial apophysis (Fig. 16B View Figure 16 ) and females by the deep, separated, anterior copulatory opening (Fig. 17A View Figure 17 ). However, the new species can be distinguished by the hook-shaped conductor (Fig. 16B View Figure 16 ) [vs conductor long and slender (see Marusik and Omelko 2018: fig. 42)], an apophysis at the base of embolus (Fig. 16A View Figure 16 ) (vs absent) and only one apophysis on conductor (Fig. 16B View Figure 16 ) [vs two apophyses (see Marusik and Omelko 2018: fig. 42)]. The female can be distinguished by the absence of anterior pockets (Fig. 17A View Figure 17 ) [vs present (see Ovtsharenko et al. 1994: fig. 51)] and the copulatory ducts connected directly to the anterior part of spermatheca (Fig. 17B View Figure 17 ) [vs copulatory ducts wrap around spermatheca and then connect to the middle of spermatheca (see Ovtsharenko et al. 1994: fig. 52)].
Description.
Male holotype (Fig. 20A View Figure 20 ). Total length 3.13; carapace 1.38 long, 1.05 wide, opisthosoma 1.67 long, 0.92 wide. Eye sizes and interdistances: AME 0.04, ALE 0.04, PME 0.03, PLE 0.04, AME-AME 0.02, AME-ALE 0, PME-PME 0.01, PME-PLE 0.01, AME-PME 0.03, ALE-PLE 0.02. Anterior eye row slightly recurved, posterior eye row straight. Chelicerae with three promarginal and three retromarginal teeth. Legs with long brown hair. Leg measurements: I 4.51 (1.20, 1.83, 0.83, 0.65), II 3.20 (0.90, 1.19, 0.62, 0.49), III 3.53 (1.05, 1.19, 0.62, 0.49), IV 3.21 (0.71, 0.83, 1.11, 0.56). Opisthosoma oval, venter brown with long hair, dorsal scutum absent. Spinnerets pale yellow.
Palp (Fig. 16A-C View Figure 16 ). Femur and patellar without apophysis. Tibia almost as long as patella. Retrolateral tibial hood (RTH) almost 2 × wider than long, terminal part slightly curved. Cymbium almost 1.5 × longer than wide. Subtegulum (ST) indistinct, hidden between cymbium and tegulum. Tegulum round. Conductor (C) tip strongly curved, without serration, basal with an apophysis, triangle shaped. Embolus (E) whip-like, basal part with an apophysis, originates at 6 o’clock position.
Female paratype (IZCAS-Ar44460) (Fig. 20B View Figure 20 ). Total length 2.75; carapace 1.26 long, 0.88 wide, opisthosoma 1.54 long, 0.97 wide. Eye sizes and interdistances: AME 0.04, ALE 0.04, PME 0.05, PLE 0.04, AME-AME 0.01, AME-ALE 0.01, PME-PME 0.02, PME-PLE 0.01, AME-PME 0.03, ALE-PLE 0.01. Anterior eye row almost straight, posterior eye row recurved. Chelicerae as in male. Leg measurements: I 2.71 (0.83, 1.02, 0.46, 0.40), II 2.33 (0.71, 0.82, 0.44, 0.36), III 2.03 (0.65, 0.61, 0.42, 0.35), IV 3.07 (0.85, 1.11, 0.69, 0.42). Opisthosoma oval, venter yellow-brown with long brown hair. Spinnerets pale yellow.
Epigyne (Fig. 17A, B View Figure 17 ). Epigynal plate almost as long as wide. Copulatory openings (CO) located anteriorly, separated by median septum (MS). Copulatory duct (CD) short, connected to anterior part of spermatheca. Glandular appendage (GA) distinct, anteriorly. Spermathecae (S) kidney-shaped, almost 2 × wider than long. Fertilization ducts (FD) directed at 2 o’clock position from spermathecae.
Distribution.
Known only from the type locality.
Etymology.
The species is named after Lei Heng, one of the 108 outlaws in the classical Chinese novel 'Outlaws of the Marsh’; noun in apposition.
