RESUMO

This work presents a taxonomic revision of New World Pyrgotidae, currently composed of 66 valid species names distributed in 15 genera. The taxonomic revision resulted in the description of two new genera and two species, synonymy of four genera and 18 species and revalidation of 1 species. According to these results, the Pyrgotidae of the New World contains 51 valid species arranged in 12 genera. Phylogenetic analyses were conducted to test the monophyly of the genera, establish the relationships among their species, and test the performance of continuous characters in the phylogeny of Pyrgotidae. Fifty-four morphological characters of adults were coded and divided as: 14 continuous and 40 discrete. Continuous and discrete characters were analyzed separately and under total evidence. The analyses using only discrete characters and in total evidence each resulted in one tree, which were very similar, diverging only in the positions of three terminals. In the tree obtained using total evidence, the branch support increased in more branches, which demonstrates that continuous characters are phylogenetically informative for use in analyses of the Pyrgotidae.
