Abstract

By means of reference material and literature reviews, as well as entomological surveys, we documented the taxonomic composition of the order Orthoptera within the biogeographic provinces of Atacama and Coquimbo, and identified the relationships between the spatial distribution of species and the plant formations described from these provinces. We recorded the presence of 68 species, 37 genera, and 9 families. The most diverse family was Tettigoniidae, followed by Proscopiidae and Acrididae. High species richness was observed in only 4 of the 23 plant formations analyzed. The areas with the highest number of species were the coastal shrubby steppe (47 species), the interior shrubby steppe (28 species), the shrubby steppe of the precordillera of Coquimbo (14 species), and the coastal desert of Huasco (13 species). This georeferenced survey is a first attempt to identify the distribution patterns of orthopteran species within these biogeographic areas
