Etymology.

This species name a noun in apposition, derived from the Latin brunneus, and refers to the reddish brown colouration of median band of the dorsal abdomen.

Diagnosis.

This species is distinguishable from other known congeners by colour of the median band of abdomen and broad PLT in males (Fig. 8 A–C), and the relatively large spermathecae and shape of copulatory ducts (thick, stout) in females. It differs from P. alborea , P. jesudasi , and P. flavumi by comparably shorter embolus, narrower triangular ALT and from P. versicolor by comparably longer embolus, narrow ALT and short RTA. Female members obviously differ from P. orbisa and P. flavoviri by the absence of coiled CD.

Description.

Male. Live spiders, clypeus enclosed with tuft of white scales, prosoma blackish brown decorated with pale yellow band on the anterior margin of prosoma behind AME. White dots sparsely scattered on prosoma (Fig. 8 A–D). A white, prominent diamond-shaped mark behind PLE (Fig. 8 A–C). Lateral sides of prosoma with white belts (Fig. 8 A–C). In ethanol preserved specimens, chelicerae brown, prosoma yellowish brown. Posterior margin of prosoma slightly truncated (Fig. 9A). Rounded, yellowish brown sternum, edges light brown (Fig. 9B).

Abdomen moderately long and slightly narrower than prosoma, tapering posteriorly. Dorsum with much broader greenish brown median band, delimited by narrow white lateral bands extending longitudinally from anterior to posterior end (Fig. 8 A–C). Ventrum blackish grey in life and pale yellow in preserved specimens. Spinnerets greyish brown. Leg I blackish brown and robust than others, leg II, III and IV blackish yellow.

Yellowish brown palp. Cymbium shorter than P. jesudasi and slightly narrower distally. Embolus slender, long immovable on the thinner apical portion of tegulum, slightly extending beyond the level of the distal end of tegulum (Figs 9 C–E, 11A, B). Lamellar process absent. Bulbus longer than wide. Spermatophore loop clearly visible at the antero-lateral portion of bulbus. Tegulum with small posterior lobe. RTA nearly half-length of bulbus, broader at base, narrow tip hook-shaped (Figs 9D, E, 11A, B).

Female. Ethanol preserved specimens, prosoma yellowish brown, ALE, PME, PLE covered with black blotches (Fig. 10E, F). Chelicerae, labium yellowish brown, edges brown. Pentagon-shaped sternum, pale yellow, edges light brown (Fig. 10F). Posterior prosoma steep and slightly truncated. Leg I dark yellowish brown, slightly robust than rests. Legs II, III, and IV yellow.

Abdomen moderately long and slightly broader than prosoma, tapering posteriorly. Dorsum with two yellowish brown stripes extending longitudinally from anterior portion to near spinnerets (Fig. 10E). Middle of dorsum decorated with two pairs of dark yellowish brown spots. Ventrum pale brown. Spinnerets yellow.

Epigynum moderately sclerotised. DDC is shorter compared to its congeners (Figs 10G, H, 11C, D). Position of CO unclear, could be laterally outwards. Comparably shorter CD is twisted near DDC. Spermathecae large and rounded (Fig. 10G, H). FD lanceolate originating from apical portion of receptacles (Figs 10H, 11D). PEB comparably thinner than other congeners.
