On the Identity of Species of Oreobates (Anura: Craugastoridae) from Central So...

Made available in DSpace on 2022-04-29T08:29:06Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-12-01; The similar morphology of species in the genus Oreobates that inhabit rocky outcrops amidst the Seasonally Dry Tropical Forests and Cerrado savannas of central South America has led to taxonomic inaccuracies when only external morphology was considered. Therefore, researchers frequently fail to determin...

New records and distribution extensions of three species of Mesoclemmys Gray, 1...

Distribution patterns of most of the 20 Neotropical freshwater turtles belonging to the family Chelidae are usually based on few locality records. We here report on vouchered records of three species of the chelid genus Mesoclemmys in the Brazilian state of Mato Grosso. Presence of M. vanderhaegei is confirmed for the Amazon River Basin, and M. gibba and M. raniceps are recorded in Mato Grosso for the first tim...

Evaluation of the taxonomic status of populations assigned to Phyllomedusa hypo...

Background: The taxonomic and phylogenetic relationships of the genus Phyllomedusa have been amply discussed. The marked morphological similarities among some species hamper the reliable identification of specimens and may often lead to their incorrect taxonomic classification on the sole basis of morphological traits. Phenotypic variation was observed among populations assigned to either P. azurea or P. hypoch...
