Figures 27–42

Etymology. The species epithet is a noun in apposition in honor of the Polish salticidologist Dr. Wanda Wesołowska, for her contributions to the study of salticids.

Diagnosis. Male Peckhamia wesolowskae sp. nov. ( Figs 31 , 36 ) can be distinguished from other Peckhamia by the embolus with the rR reduced and the pbR truncated and developed. Female P. wesolowskae sp. nov. ( Fig. 33 ) can be distinguished by lacking the abdominal white area ( Fig. 28 ), which is present in P. areito sp. nov. ( Fig. 2 ), P. espositoae sp. nov. ( Fig. 9 ), P. surcaribensis sp. nov. ( Fig. 21 ), P. formosa comb. nov. and P. magna comb. nov. ( Fig. 52 ); the CD without an ovoid coil, which is present in P. espositoae sp. nov. ( Fig. 14 ) and P. magna comb. nov. ( Fig. 53 ); the SS that is longer than wide, while SS as long as wide in P. espositoae sp. nov. ( Figs 14 ) and P. formosa comb. nov. ( Fig. 51 ) and separated from the PS; and SS close to PS in P. formosa comb. nov. ( Fig. 51 ).

Description. Male (Holotype, ICN-Ar-12800). Coloration ( Fig. 41 , in alcohol): Carapace dark reddish, almost black in interocular region. Chelicerae reddish; endites and labium gray to pale yellow. Leg I yellow to reddish; legs II–IV, pale gray to dark brown. Abdomen ventrally gray to black; dorsally, reddish to black with sparse white scales. Total length 4.0. Carapace 1.8 long, 1.1 wide at position of PLE, 0.65 high, 0.59 times wider than high, flat from AME to PLE, then with a soft descent to an inconspicuous groove just behind PLE; carapace 0.56 times longer than OQ. AER 0.85 wide, PER 1.05 wide. OQ 1.0 long, slightly longer than wide. Clypeus 0.1 high and lacking decoration. Sternum longer than wide, 0.7 long, 0.32 wide. Abdomen 2.0 long, with very slight constriction of the anterior third. Legs 4213; leg I: femur 1.0 long, 0.55 wide; patella 0.65 long, 0.25 wide; patella somewhat flattened dorsally; femur wide dorsally. Palpal structure as in Figs 30–32 , 35–36 : femur straight, 0.56 times longer than wide, femur 0.5 times longer than patella+tibia; RTA dark, wide ( Fig. 32 ); embolus, pdR very elongated and thin compared to rR, pbR truncated and developed.

Female (Paratype, ICN-Ar-12801). Coloration as in male ( Fig. 42 , in alcohol). Total length 3.3. Carapace 1.6 long, 0.8 wide, 0.7 high; 0.53 times longer than OQ. Clypeus 0.1 high. AER 0.85 wide, PER 1.0 wide. OQ length 0.85. Sternum 0.75 long, 0.4 wide. Abdomen 1.55 long, longer than wide. Leg formula 4213; leg I: femur 0.85 long, 0.43 wide; patella 0.55 long, 0.2 wide. Genitalia ( Fig. 33 ): WE occupying much more than 1/2 of epigynal plate; CD curved; SS developed, longer than wide; PS as wide as CD; FD distant from CD; BG depressed or superficial.
