The results of research on the jumping spiders of the Nimba Mountains (the Guinean part), biodiversity hotspot in West Africa, are presented. A new genus is established, Yeiyei gen. nov. with the type species Yeiyei guiparkeri sp. nov. Thirty species are described as new for science: Bacelarella arcana sp. nov. (♀), B. magnifica sp. nov. (♀), B. regularis sp. nov. (♀), Detalik solitaria sp. nov. (♀), Evarcha albofacialis sp. nov. (♂), E. ampulla sp. nov. (♂), E. difficilis sp. nov. (♀), E. magna sp. nov. (♂), Finger jamisonsuteri sp. nov. (♂♀), Heliocapensis lola sp. nov. (♀), Lamottella mirabilis sp. nov. (♂♀), Lictor newene sp. nov. (♂), Malizna guineensis sp. nov. (♀), M. simplex sp. nov. (♂♀), Menemerus lobatus sp. nov. (♂), Nimbarus acer sp. nov. (♂♀), N. digitatus sp. nov. (♂♀), N. trilobatus sp. nov. (♂), N. zie sp. nov. (♂♀), N. zouguepo sp. nov. (♂♀), Pochytoides consobrinus sp. nov. (♂♀), P. Limpidus sp. nov. (♀), Pulcherula scintillans sp. nov. (♀), Rhene gbakore sp. nov. (♀), Sadies africana sp. nov. (♀), Thiratoscirtus lativittatus sp. nov. (♀), T. seringbarensis sp. nov. (♂), T. similis sp. nov. (♂), T. tibialis sp. nov. (♂) and Yeiyei guiparkeri sp. nov. (♂♀). Two specific names are synonymized: Langona recta Wesołowska and Russell-Smith, 2022 with L. trifoveolata (Lessert, 1927) and Viciria equestris pallida Berland and Millot, 1941 with Vicirionessa equestris (Simon, 1903). Brancus lacrimosus Wesołowska and Edwards, 2012 and Viciria prenanti Berland and Millot, 1941 are removed from their synonymy with Vicirionessa fuscimana (Simon, 1903) and are recognized as synonyms of V. albocincta (Thorell, 1899). The unknown males of Langelurillus horrifer Rollard and Wesołowska, 2002, Menemerus dubius Berland and Millot, 1941 and Gramenca prima Rollard and Wesołowska, 2002, and the unknown females of Asemonea virgea Wesołowska and Szűts, 2003, Lamottella longipes Rollard and Wesołowska, 2002, Nimbarus pratensis Rollard and Wesołowska, 2002, Phintella minor (Lessert, 1925), Pochyta konilokho Wesołowska and Szűts, 2021, Pulcherula magna Wesołowska and Russell-Smith, 2022 and Thyene bucculenta (Gerstaecker, 1873) are described for the first time. As a result of this study, the list of salticids from the Nimba Mountains contains 131 species (previously only 25).
