Etymology. The epithet commemorates the career and life of Polish Professor Wanda Wesołowska. During her career, she has authored/co-authored the description of hundreds of jumping spider species.

Diagnosis. Among all Marma species, Marma wesolowskae sp. nov. shares most similarities with M. nigritarsis and M. pipa sp. nov. The males of these species have an embolic disc with a straight prolateral border and curved retrolateral border ( Figs 25C View FIGURE 25 , 27A View FIGURE 27 , 30C View FIGURE 30 , 32A View FIGURE 32 , 36C View FIGURE 36 , 37A View FIGURE 37 , 57 View FIGURE 57 C–E). Besides, in the females, the copulatory ducts do not touch each other and they encircle the primary spermathecae ( Figs 26 View FIGURE 26 C–D, 27F–G, 31C–D, 32F–G, 35H–I, 37H–I, 58E–G). The males of M. wesolowskae sp. nov. differ from the males of these species by having a narrower embolic disc ( Figs 30C View FIGURE 30 , 32A View FIGURE 32 , 57 View FIGURE 57 C–E), and the females differ by having the posterior border of the epigynal plate projected and the copulatory openings placed more posteriorly (posterior to the distal region of the primary spermathecae) ( Figs 31 View FIGURE 31 C–D, 32G, 58E–G).

Description. Male (Holotype, MPEG 34355). Total length: 3.38. Carapace 1.96 long, 1.31 wide, 0.97 high. Ocular quadrangle 0.78 long. Anterior eye row 1.18 wide, posterior 0.97 wide. Legs 3412.
