Description

Male carapace pale brown, with distinct, black, marginal and submarginal bands, both bands connected by one or two radial stripes. Anterior eye row recurved, posterior eye row procurved and slightly wider. Fovea dark, longitudinal and bar shaped. Sternum pale brown and without pattern. Chelicerae 1.10 long, coloured as carapace, median area with dark spot, three promarginal and four retromarginal teeth. Labium slightly wider than long. Legs coloured as carapace, with distinct black annuli; tibiae I and II with eight and six pairs of long ventral spines, respectively, with longest spine 0.92. Metatarsi I and II with three pairs of long ventral spines, with longest spine 0.97. Opisthosoma ovoid.

Dorsum paler than carapace, anterior lateral area with a pair of diagonal, dark bands, median and posterior area scattered with many white spots; and with two pairs of muscular impressions ( Figure 2View Figure 2. P (a)). Venter whitish yellow, paler than dorsal, marginal area with irregular, black spots. Spinnerets pale brown, anterior one cylindrical and longest, median one conical and shortest, and posterior cylindrical with tapered distal end.

Palpal organ with coxae 0.2 7 long, 0.21 wide. Femur 0.95 long, longer than wide, with a promarginal dark spot, and two dorsal and one retrolateral, strong spines, and one weaker, prolateral spine. Patella 0.40 long, about 0.23 X shorter than femur, with one prolateral and dorsal spine each. Tibia 0.32 long with one dorso-retrolateral apophysis ( Figures 2View Figure 2. P (c),(d), 5View Figure 5. (b)), and two prolateral spines ( Figures 2View Figure 2. P (b),(c), 5View Figure 5. (a),(b)). Cymbium 1.01 long and without spines. Genital bulb globular ( Figures 2View Figure 2. P (b), 5View Figure 5. (a)). Embolus originating from anterior portion of the bulb, its narrower portion about 0.5 X as long as the wider portion. Conductor short, its distal portion much wider and with two rami ( Figures 2View Figure 2. P (b), 5View Figure 5. (a)).

Measurements. Male total length 3.70 (variation 3.12 – 3.75), carapace 1.9 5 long, 1.80 wide, 1.0 0 high. Clypeus very low, 0.05. AME 0.15, ALE 0.10, PME 0.16, PLE 0.15, AME – AME 0.08, AME – ALE 0.07, AME – PME 0.09, PME – PME 0.10, PME – PLE 0.16, ALE and PLE touching each other. Leg I 8.45 (2.40, 3.40, 1.95, 0.70), II 6.84 (2.06, 2.61, 1.52, 0.65), III 6.55 (1.93, 2.28, 1.61, 0.73), IV 6.64 (1.80, 2.05, 1.97, 0.82), formula: I, II, IV, III.

Etymology

The specific name is derived from the type locality.

Comments

This new species resembles P. indicus  ( Marusik et al. 2008: Figures 8 – 11), but distinct in its (1) embolus originating from the anterior portion of genital bulb ( Figures 2View Figure 2. P (b),(c), 5View Figure 5. (a), (b)) (vs. originating from the median portion); (2) narrower portion of embolus about 0.5 X as long as its wider portion ( Figures 2View Figure 2. P (b), 5View Figure 5. (a)) (vs. about as long as its wider portion); (3) conductor much shorter, its distal portion much wider and with two rami ( Figures 2View Figure 2. P (b), 5View Figure 5. (a)) (vs. distal portion bar shaped); (4) tibia with two strong spines ( Figures 2View Figure 2. P (b),(c), 5View Figure 5. (a),(b)) (vs. with only one spine).
