| Abstract: | The endemic hyperoliid treefrogs of São Tomé and Príncipe currently recognized as Nesionixalus thomensis (Bocage, 1986) and N. molleri (Bedriaga, 1892) are re-examined. The results of two molecular analyses indicate that these taxa are closely related to each other (monophyletic) but nest within the genus Hyperolius. Acomparison of the morphological character states used by Perret (1976; 1988) to erect the genus Nesionixalus from within Hyperolius Rapp with a broad range of Hyperolius species reveals that most of these are not unique to the island endemics; all except the characters of size and digital tip shape are distributed among a number of other species within the latter genus. Nesionixalus Perret, 1976 is returned to the synonymy of Hyperolius Rapp and Nesionixalus thomensis and N. molleri to Hyperolius thomensis Bocage and H. molleri Bedriaga, respectively. |
