Types.

Holotype: ♂ (IZCAS), Vietnam, Dong Nai Province, Cat Tien National Park, 11°27.3620'N, 107°26.4980'E, 168 m, 4.IX.2015, Q. Zhao, Y. Li & Z. Chen. Paratype: 1♀ (IZCAS), same data as holotype.

Etymology.

The species name is an adjective referring to the type locality.

Diagnosis.

Males of P. cattienensis sp. nov. resemble those of P. pingguo sp. nov. but can be distinguished by the relatively long embolus, which is equal to the length of the tegulum (vs. embolus two times shorter than the tegulum), the bulb is rather angular (vs. bulging); females can be distinguished by the merged tubular spermathecae (vs. stalked spermathecae globose distally).

Description.

Male (Holotype). Total length 1.32; carapace 0.44 long, 0.47 wide; abdomen 0.88 long, 0.50 wide. Carapace round and brown, with trident brown stripes medially and dark brown patches laterally (Fig. 10D View Figure 10 ). Chelicerae brown, cheliceral promargin with lamina bearing 2 triangular extensions (Fig. 10C, D View Figure 10 ). Endites dark brown. Labium dark brown delimiting pair of indistinct light brown circular dots. Sternum dark brown, delimiting light brown band medially. Abdomen elongated, dorsum with complex dark brown patterns, antero-ventrally dark brown with elliptical patch, posterior with 4 pairs of light brown vertical lines laterally and medially. Legs uniformly brown; measurements: I missing, II 3.45 (0.94, 0.13, 0.88, 0.94, 0.56), III 2.94 (0.81, 0.13, 0.81, 0.75, 0.44), IV missing. Palp (Fig. 11A-D View Figure 11 ): femur slender, 4 times longer than patella; patella not swollen; tibia 2 times shorter than femur; cymbium almost as long and wide as tibia, cymbial protrusion darkens distally; bulb pale brown, widely turbinate with embolus arising distally; embolus slightly bent at tip, almost as long as entire bulb (Fig. 11B View Figure 11 ).

Female (Paratype). General features and coloration similar to those of male (Fig. 10E, F View Figure 10 ). Measurements: total length 1.28; carapace 0.47 long, 0.55 wide; abdomen 0.81 long, 0.47 wide. Leg measurements: I 4.49 (1.13, 0.16, 1.41, 1.09, 0.70), II 3.53 (0.90, 0.20, 1.02, 0.86, 0.55), III 2.94 (0.75, 0.16, 0.81, 0.75, 0.47), IV 4.11 (1.00, 0.13, 1.33, 1.02, 0.63). Endogyne (Fig. 10A View Figure 10 ): spermathecae with lobes, cylindrical anteriorly and oval posteriorly, anterior lobes extended anteriorly and posterior lobes extended laterally.
