The paper presents data on the first records and new records of jumping spiders (Salticidae) from the Caspian Depression. A new species, Chalcoscirtus logunovi Ponomarev, sp. n., is described based on a series of females previously erroneously identified as Chalcoscirtus platnicki Marusik, 1995. Female of Ch. platnicki is described for the first time. Phenotypic variability of five species, Attulus nenilini (Logunov et Wesołowska, 1993), Euophrys uralensis Logunov, Cutler et Marusik, 1993, Evarcha arcuata (Clerck, 1758), Marusyllus aralicus (Logunov et Marusik, 2003), Yllenus turkestanicus Logunov et Marusik, 2003, are described. Nine species are first recorded for West Kazakhstan Region and one species, Talavera milleri (Brignoli, 1983), for Kazakhstan. The fauna of the Caspian Depression currently includes 87 salticid species; the tribes Plexippini, Leptorchestini, Chrysillini and Euophryini are represented by the largest number of species. The number of jumping spider species in zonal faunas of the Caspian Depression increases from north to south, from 16 species in the steppe zone to 40 in the semi-desert zone and 78 in the desert zone.
