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, 27A, 30C, 32A, 36C, 37A, 57 C–E). Besides, in the females, the copulatory ducts do not touch each other and they encircle the primary spermathecae (Figs 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, 32A, 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 C–D, 32G, 58E–G).
