Figures 27–42 View FIGURE 27–33 View FIGURES 34–36 View FIGURES 37–42

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 View FIGURE 27–33 , 36 View FIGURES 34–36 ) 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 View FIGURE 27–33 ) can be distinguished by lacking the abdominal white area ( Fig. 28 View FIGURE 27–33 ), which is present in P. areito   sp. nov. ( Fig. 2 View FIGURE 1–7 ), P. espositoae   sp. nov. ( Fig. 9 View FIGURE 8–14 ), P. surcaribensis   sp. nov. ( Fig. 21 View FIGURE 20–26 ), P. formosa   comb. nov. and P. magna   comb. nov. ( Fig. 52 View FIGURE 49–55 ); the CD without an ovoid coil, which is present in P. espositoae   sp. nov. ( Fig. 14 View FIGURE 8–14 ) and P. magna   comb. nov. ( Fig. 53 View FIGURE 49–55 ); the SS that is longer than wide, while SS as long as wide in P. espositoae   sp. nov. ( Figs 14 View FIGURE 8–14 ) and P. formosa   comb. nov. ( Fig. 51 View FIGURE 49–55 ) and separated from the PS; and SS close to PS in P. formosa   comb. nov. ( Fig. 51 View FIGURE 49–55 ).
