Abstract
The fourth genus and species of the Cretaceous aeshnopteran family Liupanshaniidae discovered in the Aptian Crato Formation, is described and illustrated as Brasiliupanshania cretacica gen. et sp. nov. Its phylogenetic position within the Liupanshaniidae is investigated using parsimony analyses, and it was found nested within the Liupanshaniidae. The Gondwanan species of the family do not form a clade, but appears to be more closely related to various Laurasian clades, suggesting a very ancient Mesozoic diversification prior to Gondwana–Laurasia split.
