Abstract

<abstract abstract-type="main"> <title> <x xml:space="preserve">Abstract</x> </title> <p>The chelodesmid genus <italic>Odontopeltis</italic> Pocock, 1894, is revised. It currently contains eight species, four of which are described as new here: <bold><italic>Odontopeltis aleijadinho</italic> sp. nov.</bold>, <bold><italic>Odontopeltis donabeja</italic> sp. nov.</bold>, <bold><italic>Odontopeltis tiradentes</italic> sp. nov.</bold>, and <bold><italic>Odontopeltis xica</italic> sp. nov.</bold> Additional descriptive data are provided for <italic>Odontopeltis anchisteus</italic> Hoffman, 1981, <italic>Odontopeltis clarazianus</italic> (Humbert & deSaussure, 1869), <italic>Odontopeltis giganteus</italic> Schubart, 1849, and <italic>Odontopeltis conspersus</italic> (Perty, 1844); for the latter species a neotype is designated herein. The current position of all species ever associated with the genus is presented. Examination of type material revealed that the following species are not members of the genus <italic>Odontopeltis</italic>: <italic>Odontopeltis balzanii</italic> Silvestri, 1895, <italic>Odontopeltis borellii</italic> Silvestri, 1895, <italic>Polydesmus gracilipes</italic> Humbert & deSaussure, 1870, and <italic>Odontopeltis proxima</italic> Silvestri, 1895. The type specimen of <italic>Rhacophorus decoloratus</italic> Koch, 1847, is lost and the species is considered <italic>incertae sedis</italic>. The terminology of gonopod structures is discussed. A phylogenetic analysis of <italic>Odontopeltis</italic> based on 47 morphological characters, with species of the genus <italic>Odontopeltis</italic> and six outgroup taxa is presented. <italic>Odontopeltis</italic> is monophyletic, with <italic>Rondonaria</italic> as its closest sister‐group. The included members of the tribe Telonychopodini (<italic>Pantanalodesmus, Telonychopus</italic>, and <italic>Manfrediodesmus</italic>) form a monophyletic group; the tribe Macrocoxodesmini (<italic>Macrocoxodesmus</italic> and <italic>Eucampesmella</italic>) is paraphyletic in this data set. © 2013 The Linnean Society of London</p> </abstract>
