Notes on the distribution and ecoregion associations of ant-like jumping spiders of the tribe Sarindini Simon, 1901, with a correction of the distribution of Sympolymnia shinahota Perger & Rubio 2021 (Simonellini) (Araneae: Salticidae)

Abstract Sampling in five locations in four forest ecoregions of Bolivia revealed seven species of the ant-like jumping spider tribe Sarindini. Six species, Martella utingae, Sarinda armata, Sarinda marcosi, Simprulla argentina, Simprulla nigricolor, and Zuniga magna, are reported for Bolivia for the first time. The new Bolivian records for M. utingae, S. armata, and S. nigricolor considerably extend the distributional ranges of these species, and the new record for Z. magna shortens a large gap in the known distribution. While the dry diagonal that separates Amazon and Atlantic forests does not appear to act as a dispersal barrier for several Sarindini species, other species appear to be restricted to the areas north or south of the dry diagonal, respectively. Accordingly, high species richness in Bolivian Sarindini may be attributed to the presence of wide spread generalist species and the meeting of several super-regions with their respective faunal elements in Bolivia.
