Etymology. This species is named in honour of Prof Wanda Wesołowska (Wrocław, Poland), in recognition of her significant contributions to the taxonomy of African and Palaearctic Salticidae   .

Diagnosis. Male of this species differ from congeners in the shape of the RTA that is almost as long as the width of the bulb, with the tip directed laterad ( Fig. 28 View FIGURES 26–30 ). The RTA base is broad and the apex is beak-like, in contrast to the sharply pointed apex of P. martini   . The abdomen has a hump that is more distinct in males, while in P. martini   the abdomen profile is round. The atrium of the female epigyne is egg-shaped, as wide as long, with the ventral edge thickened ( Fig. 29 View FIGURES 26–30 ), and the spermathecal ducts are long and curved ( Fig. 30 View FIGURES 26–30 ).

Description. Holotype male. Measurements: TL 1.90; CL 0.91; CW 0.95. Legs: I 1.45 (0.52, 0.12, 0.31, 0.28, 0.22); II 1.45 (0.63, 0.23, 0.29, 0.20, 0.10); III 1.08 (0.34, 0.12, 0.32, 0.20, 0.10); IV 1.31 (0.46, 0.15, 0.32, 0.19, 0.19). Carapace: dark brown, darker laterally, strongly granulated, bearing numerous small tubercles, each with translucent seta ( Fig. 26 View FIGURES 26–30 ); eyes circled with black; chelicerae brown; mouthparts yellowish brown. Sternum brown, granulate. Legs dark; coxae, trochanters and tibiae brown, with blackish hue; femora I–IV dark brown, with femora I–II usually darker than rest; patellae yellowish brown; all legs with distinct white bands at joints distinct when viewed from below. Abdomen dorsum with brown scutum, with scattered black patches; in lateral view with distinct hump; white laterally and pale below. Palp with large beak-like RTA ( Fig. 28 View FIGURES 26–30 ); tip directed laterad with small VTA.

Female. Measurements: TL 2.26; CL 0.97; CW 1.10. Legs: I 1.90 (0.67, 0.29, 0.42, 0.25, 0.27), II 1.82 (0.60, 0.27, 0.43, 0.24, 0.28); III 1.21 (0.42, 0.22, 0.26, 0.12, 0.19); IV 1.42 (0.55, 0.16, 0.28, 0.31, 0.12). Resembles the male but larger in size and paler in colour ( Fig. 27 View FIGURES 26–30 ). Carapace fawn to brown, with dark patch laterally; eyes circled with black; eye region infused with white; chelicerae fawn; integument strongly granulated, bearing numerous small tubercles, each with translucent seta. Sternum granulated, bearing tubercles with setae. Legs same colour as prosoma; white with distinct white bands at joints; femora darker. Abdomen white with dark patches, scattered dark setae giving it spotted appearance; abdomen with hump less distinct than in male. Epigyne with sub-oval atrium, slightly wider than long, edges slightly thickened ( Fig. 29 View FIGURES 26–30 ); spermathecae slightly longer than wide, with long curving spermathecal ducts ( Fig. 30 View FIGURES 26–30 ).
