RESUMO

In order to contribute to the taxonomy of Tricorythodes Ulmer and Tricorythopsis Traver, new taxa were described and molecular techniques were used as complementary tools in the systematic of the Ephemeroptera. As a result of the work, five new species were described, three for genus Tricorythodes (T. rondoniensis, T. sallesi and T. caunapi) and two for Tricorythopsis (T. bahyensis and T yucupe), besides the first record of Tricorythodes quizeri Molineri from Brazil. A phylogenetic analysis of Tricorythodes was carried out for the first time using molecular data of three markers (18SrDNA, 16SrDNA and COI) combined with 39 morphological characters. This analysis supported the monophyly of Tricorythodes, except for the species of Asioplax Wiersema &McCafferty e Macunahyphes Dias, Salles &Molineri. Therefore this work presents evidence for Asioplax e Macunahyphes revalidation as genus of Leptohyphidae. The results of this work presented also that the AFLP molecular technique constitute a useful tool to the association of adults and nymphs of Ephemeroptera. From this methodology the unknown adult of Leptohyphes ecuador Mayo was associated with its nymph by DNA fingerprint. In addition, the description of the adults of L. ecuador and the first record of this species from Colombia were present.
