A review of the southern South American Triassic coleopteran fauna as well as a phylogenetical approach resulting from its analysis is presented. This work provides new tools for the study of fossil coleopteran elytra, based in its morphological aspects, its fossil record in the Middle to Late Triassic levels from southern South America basins, and by the record of speciation episodes in the assemblages. Additionally, an area cladogram and a probable phylogenetic scheme for the coleopteran fauna are provided and suggestions to age insertion and correlation are also presented.
Key words: Triassic, Coleoptera, Paleobiogeography, Phylogeny, South America, Morphometry.Downloads
