Treatment

Merizocera baoshan Li sp. nov. Figures 1 View Figure 1 , 2 View Figure 2 , 53 View Figure 53

Type material.

Holotype: male (IZCAS), Luoshui Cave (25°20.35'N, 98°32.28'E, elevation 1937 m), Jiangdong Mountain, Jiangdong Village, Gudong Town, Tengchong County, Baoshan, Yunnan, China, 15 July 2016, Y. Li leg. Paratypes: 3 males and 3 females (IZCAS), same data as holotype.

Etymology.

The specific name refers to the type locality; noun in apposition.

Diagnosis.

Males of M. baoshan sp. nov. resemble those of M. tengchong sp. nov., but can be distinguished by the pointed and bent tip of the embolus (Fig. 1B View Figure 1 ) (vs. blunt and upright tip of embolus (Fig. 40B View Figure 40 )); a distinct stalked apophysis bearing a pointed distal tip adjacent to the embolus (Fig. 1B View Figure 1 ) (vs. stalked apophysis bearing globose distal tip (Fig. 40B View Figure 40 )); a cymbial protrusion half the length of the tegular (Fig. 1D View Figure 1 ) (vs. cymbial protrusion 1/4 the length of tegular (Fig. 40D View Figure 40 )). The female can be distinguished from congeners by a pair of flattened ovoid spermathecae.

Description.

Male (holotype). Total length 1.65; carapace 0.75 long, 0.61 wide; abdomen 0.80 long, 0.55 wide. Carapace circular, brownish, with dark brown marks laterally and dark brown median line on anterior half (Fig. 2C View Figure 2 ). Fovea shallow. Thoracic region distinctly elevated medially. Clypeus, labium and sternum dark brown. Abdomen ovoid, dark brown (Fig. 2C View Figure 2 ). Legs light brown; measurements: I and II missing, III 4.02 (1.13, 0.22, 1.13, 0.98, 0.56), IV 5.70 (1.48, 0.25, 1.70, 1.44, 0.83). Palp (Fig. 1A-D View Figure 1 ): femur slender, three times longer than patella; patella not swollen; tibia 2/3 length of femur; cymbium with distal protrusion, 1/3 length of femur, length ratio of dorsal protrusion and cymbium 0.57; bulb light brown, elongated pyriform with embolus, conductor and stalked apophysis emerging distally; embolus similar in length and 1/3 the width of tegular, with darkened pointed tip and bent at right angle; conductor tentacle-like, basally attached with embolus; stalked apophysis basally attached with embolus, bearing triangular pointed distal part.

Female (paratype). General features and colouration similar to those of male (Fig. 2D, E View Figure 2 ). Measurements: total length 1.68; carapace 0.71 long, 0.61 wide; abdomen 0.94 long, 0.80 wide. Leg measurements: I 4.75 (1.24, 0.25, 1.42, 1.14, 0.70), II 3.92 (1.04, 0.25, 1.10, 0.82, 0.61), III 3.27 (0.87, 0.22, 0.88, 0.80, 0.50), IV 4.76 (1.24, 0.24, 1.39, 1.13, 0.76). Epigastric area (Fig. 2B View Figure 2 ): brown, with a pair of slanting, short, pale brown bands anteriorly, posterior spanned with pale brown horizontal band. Endogyne (Fig. 2A View Figure 2 ) with pair of connected, flattened, ovoid spermathecae.
