Merizocera wenshan Li sp. nov. Figures 45, 46, 53

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) (vs. narrow and thin embolus (Fig. 47B)), absence of a conductor (vs. presence of a short conductor (Fig. 47B)), a short and wide cymbium protrusion (Fig. 45D) (vs. long and thin cymbium protrusion (Fig. 47D)), and a pyriform bulb (Fig. 45B) (vs. spherical bulb (Fig. 47B)). Females can be distinguished by a pair of upright tubular spermathecae (Fig. 46A) (vs. a pair of angled clavate spermathecae (Fig. 48A)).

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). 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): 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). 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): dark brown semi-circular patch. Endogyne (Fig. 46A) with a pair of anteriorly directed tubular spermathecae, ratio of the width of a spermatheca to the interdistance of spermathecae 1:5.
