Cicada (Cicadoidea) sampling yielded approximately 700 specimens. These represented 20 different genera and 38 different species. Our goal was was to collect as many taxa and specimens as possible, from as many different habitats as possible, since the cicada fauna is so poorly known. We visited the majority of the provinces North of Buenos Aires, including Buenos Aires, Entre Ros, Corrientes, Misiones, Santa Fe, Chaco, Santiago del Estero, Salta, Jujuy and Tucumn. We used several types of traps: light trap, malaise trap, vacuuming, sweeping, beating and search (both at night and during the day). Of the 38 species collected, 10 species are probably new to science, and one morphospecies remains to be identified. For all species we took samples for molecular study (either legs in ethanol our the whole specimen), and for morphological study (field-pinned specimens). For the majority of species songs were recorded, for some species the shells were also collected.
