Associated scholarship(s):18/23224-5 - Comparative analysis of forewings and phylogeny of Tafaliscinae sensu Desutter (Orthoptera, Grylloidea, Gryllidae) using morphological and molecular data, BE.EP.DR


Grylloidea classification have had several controversies over the years. Higher-level phylogenies for Orthoptera, Ensifera and Grylloidea recently started to clarify these relationships. The subfamily Tafaliscinae sensu Desutter 1987, traditionally considered not valid, was recently recovered as monophyletic based on a molecular phylogenetic analysis. However, none taxonomic change to validate this clade has been proposed. Nowadays, the genera are distributed along different tribes of Podoscirtinae (Aphonoidini, Paroecanthini and Podoscirtini). Although presenting morphological differences, mainly in the wings, these exclusively Neotropical crickets share a series of features like differences on apical spurs of the hind tibiae and the ovipositor dorso-ventrally flattened. The aims of this project are to test the monophyly of Tafaliscinae sensu Desutter, 1987 through phylogenetic analysis using morphological and molecular data, to delimit Tafaliscinae composition and internal relationships (tribes and genera), to verify the relationships with other subfamilies of Gryllidae, and, moreover, to perform an evolutionary study using the ancestral state reconstruction method.
