Etymology. The species is named in honour of Prof. Wanda Wesołowska, a distinctive Polish arachnologist, world authority in salticid taxonomy and a friend of ours.

Diagnosis. The bump of male palpal femur larger than in P. nasalis ( Fig. 27 ), embolus crescent-like ( Figs 24–30 ), pars pendula visible in prolateral view ( Fig. 26 , arrow), epigynal scape bilobate ( Figs 36–37 ). Abdomen with light and dark distinctive pattern ( Figs 19 , 31 ).

Description. Male holotype ( Figs 19–29 ). Cephalothorax dark-brown, with two darker spots on eye field and black PLE surroundings ( Fig. 19 ). White hairs scarce; darker and longer bristles above anterior eyes. Abdomen light grey, darker stripe along the middle, with pale spots. Spinnerets grey. Clypeus brown ( Fig. 22 ); chelicerae, maxillae and labium greyish-brown ( Fig. 23 ). Sternum dirty-brown with darker margin. Venter light grey, darkening toward sides ( Fig. 21 ). Legs I with brown femora; other segments lighter with dark joint areas. Other legs pale, with darker rings. Leg formula: 4-1-3=2.

Remark. Male paratype with less sclerotised embolus ( Fig. 30 ) and abdominal pattern of white spots much more contrasting.

Female paratype ( Figs 31–38 ). Cephalothorax brown; eye field slightly darker ( Fig. 31 ). White hairs rather numerous; brown bristles also present above anterior eyes. Abdomen dark grey, with distinctive pattern of light chevrons. Anterior and posterior spinnerets grey-brown, median pair lighter. Clypeus brown ( Fig. 34 ). Chelicerae brown maxillae and labium similar, with lighter tips ( Fig. 35 ); sternum dirty-brown. Venter grey ( Fig. 32 ). Legs I dirty-orange with darker rings, other legs pale with darker rings ( Figs 31–33 ). Leg formula: 4-1-3-2. Epigyne as in Figs 36–38 .
