Revisiting the type series of Phyllomedusa guttata A. Lutz, 1924 (Anura: Hylidae): notes on specimens and lectotype designation

We revised the taxonomic history and composition of the type series of Phyllomedusa guttata A. Lutz, 1924, which was not defined in the original description. According to subsequent works, the type series of P. guttata comprises syntypes deposited in the Adolpho Lutz Collection at the Museu Nacional, Rio de Janeiro, Brazil, and in the United States National Museum of Natural History at the Smithsonian Institution. We reviewed the two putative lectotype desig­nations and concluded that both were invalid according to the International Code of Zoological Nomenclature. Therefore, we have updated the information on the type series of P. guttata and formally designate and describe a lectotype for Phyllomedusa guttata A. Lutz, 1924.
