Descripción:Faunistic studies, with a taxonomically complete inventory of species, provide an important source of quantitative compiled information for several and specific regions. This information can be used in diversity analysis and has great potential in setting conservation priorities. In this study, I used the relatively well known salticid spider fauna of Misiones to generate Clarke & Warwick taxonomic diversity indices. For this, information of three ecoregional salticid diversities was obtained and analyzed between Upper Parana Atlantic Forest (UPAF), Araucaria Moist Forest (AMF), and Southern Cone Mesopotamian Savanna (SCMS). Results showed differences between the three ecoregions of the province, mainly Southern savannas regarding the forests of Northern Misiones. Most species were registered in UPAF followed by AMF, however the α-taxonomic diversity of salticids was higher in SCMS than in UPAF and AMF. The β-taxonomic diversity showed that the proportions of shared species between SCMS and UPAF (or and AMF) were the lowest. The high taxonomic dissimilarity among ecoregions is an indication that the three assemblages are distant, showing a variation in their vegetation habitat and/or bioclimatic characteristics as a possible reason. The need to expand with new samples in sub-sampled or underexplored areas of Misiones remains essential, however this study contributes to information about biodiversity levels of salticid fauna in three ecoregions of Northeast Argentina, and will provide reference data for future studies for management plans.
