Type material.
Holotype: male (IZCAS), Roadside between Nahteukhu and BaAve (27°18.00'N, 97°23.27'E, elevation 535 m), Putao, Kachin State, Myanmar, 8 December 2016, J. Wu leg. Paratype: 1 female (IZCAS), same data as holotype.
Etymology.
The specific name refers to the type locality; noun in apposition.
Diagnosis.
Males resemble M. putao sp. nov. but can be distinguished by the absence of a pit on the bulb (vs. presence of a distinct pit resulting from the basal connection of embolus and conductor (Fig. 29B View Figure 29 )), presence of a relatively short clypeal protrusion (Fig. 12C View Figure 12 ) (vs. relatively long clypeal protrusion (Fig. 30C View Figure 30 ). The females can be distinguished by a pair of conically tipped spermathecae (Fig. 12A View Figure 12 ) (vs. spermathecae each with a rounded tip (Fig. 30A View Figure 30 )).
Description.
Male (holotype). Total length 1.44; carapace 0.67 long, 0.56 wide; abdomen 0.79 long, 0.74 wide. Carapace circular, brownish, with dark brown radiating marks (Fig. 12C View Figure 12 ). Fovea shallow. Thoracic region distinctly elevated medially. Clypeus brownish, with small protrusion provided with long setae. Labium dark brown. Sternum dark brown, with distinct dark radiating lines. Abdomen ovoid, dark grey (Fig. 12C View Figure 12 ). Legs light brown; measurements: I 6.87 (1.86, 0.21, 2.10, 1.92, 0.78), II 5.25 (1.44, 0.20, 1.60, 1.38, 0.63), III 3.85 (1.05, 0.19, 1.10, 1.00, 0.51), IV 5.58 (1.45, 0.21, 1.72, 1.45, 0.75). Palp (Fig. 11A-D View Figure 11 ): femur slender, four times longer than patella; patella not swollen; tibia half length of femur; cymbium with distal protrusion, half length of femur, length ratio of dorsal elongation and cymbium 0.28; bulb pale yellow, elongated pyriform with embolus and conductor arising distally; embolus hooked, almost similar in length with tegular, with pointed tip, width of anterior horizontal hooked part half width of tegular; conductor short with pointed tip, basally connected with embolus.
Female (paratype). General features and colouration similar to those of male except for the absence of clypeus protrusion (Fig. 12D, E View Figure 12 ). Measurements: total length 1.25; carapace 0.58 long, 0.49 wide; abdomen 0.69 long, 0.57 wide. Leg measurements: I 3.52 (0.89, 0.19, 1.06, 0.85, 0.53), II 2.95 (0.75, 0.19, 0.85, 0.70, 0.46), III 2.41 (0.63, 0.16, 0.63, 0.59, 0.40), IV 3.49 (0.87, 0.18, 1.05, 0.83, 0.56). Epigastric area (Fig. 12B View Figure 12 ): brown semi-circular patch with pale slit medially. Endogyne (Fig. 12A View Figure 12 ) with a pair of spermathecae each with a conical tip, posteriorly with a pair of ovoid bodies, ratio of the width of conical tip spermathecae to the interdistance of spermathecae 1:7.
