Type material.
Holotype: male (IZCAS), near Daweishan National Nature Reserve (22°54.65'N, 103°41.78'E, elevation 2070 m), Pingbian County, Wenshan, Yunnan, China, 21 May 2015, Z. Chen and Y. Li leg. Paratypes: 3 females (IZCAS), same data as holotype.
Etymology.
The specific name refers to the type locality; noun in apposition.
Diagnosis.
Males resemble M. wui sp. nov. but can be distinguished by a broad embolus (Fig. 45B View Figure 45 ) (vs. narrow and thin embolus (Fig. 47B View Figure 47 )), absence of a conductor (vs. presence of a short conductor (Fig. 47B View Figure 47 )), a short and wide cymbium protrusion (Fig. 45D View Figure 45 ) (vs. long and thin cymbium protrusion (Fig. 47D View Figure 47 )), and a pyriform bulb (Fig. 45B View Figure 45 ) (vs. spherical bulb (Fig. 47B View Figure 47 )). Females can be distinguished by a pair of upright tubular spermathecae (Fig. 46A View Figure 46 ) (vs. a pair of angled clavate spermathecae (Fig. 48A View Figure 48 )).
Description.
Male (holotype). Total length 1.28; carapace 0.62 long, 0.51 wide; abdomen 0.67 long, 0.58 wide. Carapace circular, brown, with dark brown radiating marks (Fig. 46C View Figure 46 ). Fovea shallow. Thoracic region distinctly elevated medially. Clypeus and labium dark brown. Sternum brown but dark brown laterally. Abdomen ovoid, dark brown. Legs light brown; measurements: I 3.45 (0.91, 0.22, 1.01, 0.80, 0.51), II missing, III 2.52 (0.67, 0.19, 0.65, 0.58, 0.43), IV 3.62 (0.94, 0.20, 1.05, 0.84, 0.59). Palp (Fig. 45A-D View Figure 45 ): femur slender, four times longer than patella; patella not swollen; tibia not swollen; cymbium with distal protrusion, half as long as femur; bulb pale yellow, pyriform with embolus merging distally; embolus clavate with blunt tip, similar in length to and approx. thrice narrower than tegular; conductor absent.
Female (paratype). Similar to male in colouration and general features but slightly larger (Fig. 46D, E View Figure 46 ). Measurements: total length 1.34; carapace 0.63 long, 0.55 wide; abdomen 0.71 long, 0.57 wide. Leg measurements: I 3.20 (0.81, 0.20, 0.95, 0.71, 0.53), II 2.78 (0.71, 0.22, 0.77, 0.60, 0.48), III 2.42 (0.63, 0.18, 0.63, 0.57, 0.41), IV 3.45 (0.87, 0.20, 1.04, 0.78, 0.56). Epigastric area (Fig. 46B View Figure 46 ): dark brown semi-circular patch. Endogyne (Fig. 46A View Figure 46 ) with a pair of anteriorly directed tubular spermathecae, ratio of the width of a spermatheca to the interdistance of spermathecae 1:5.
