“…Although the region of Poços de Caldas represents a traditional sampling site for anurans in Minas Gerais state (Andrade and Cardoso 1987, Cardoso and Martins 1987, Cardoso et al 1989, Cardoso and Haddad 1992, Giaretta and Sazima 1993, Vasconcelos and Giaretta 2003, Giaretta and Oliveira 2007, Santos et al 2009, Martins and Giaretta 2012a, adjacent areas across the border in São Paulo state are relatively poorly sampled. This paucity of samplings in northeastern São Paulo state, near the borders with Minas Gerais state, was already reported by Rossa-Feres et al (2011), and new records of anurans have been constantly reported for the area (Araujo et al 2007a, b, Martins and Silva 2009, Martins and Giaretta 2012b.…”

“…Of the 10 anuran species on the Minas Gerais state red list, seven were described from Poços de Caldas [besides H. beckeri and H. stenocephalus, Bokermannohyla vulcaniae (Vasconcelos and Giaretta, 2005); Phyllomedusa ayeaye (Lutz, 1966); Proceratophrys palustris Giaretta and Sazima, 1993;Scinax caldarum (Lutz, 1968); Scinax ranki (Andrade and Cardoso, 1987)], and are mostly considered as restricted to the area or known only from a few other localities, demonstrating why this region, including adjacent areas in São Paulo state (Águas da Prata, São José do Rio Pardo), is among the priority areas for conservation of Brazilian biodiversity (Ministério do Meio Ambiente 2007).…”

Vocalizations of Hypsiboas beckeri and H. stenocephalus (Anura: Hylidae), two species of the H. polytaenius group from southeastern Brazil. The analysis of anuran vocalizations is an important taxonomic tool, especially within complexes of morphologically similar species. Hypsiboas beckeri and H. stenocephalus are syntopic in their type locality (Poços de Caldas, state of Minas Gerais, Brazil), and both belong to the H. polytaenius species group. Analyzed calls of these species showed that a previous acoustic description for H. beckeri, from another locality, probably represents a distinct species. The calls of topotypical H. beckeri and H. stenocephalus differed substantially from each other, and also could be differentiated from other species of the H. polytaenius H. beckeri for the State of São Paulo. The conservation status of both studied species varies among the available red lists and should thus be revisited in the future according to new taxonomic and distributional information.Keywords: Atlantic Forest, bioacoustics, conservation, Hypsiboas pulchellus clade, Serra da Mantiqueira, taxonomy.

“…Peixoto ( , 1987 characterized the Ololygon perpusilla species group, using many characters, of which the putative synapomorphies are the oviposition on water in the axils of terrestrial bromeliads and reduced webbing (absent between toes I and II and reduced or absent between toes II and III). Andrade and Cardoso (1987) defined the Ololygon rizibilis species group (as Hyla) by the presence of a laterally expanded vocal sac. They included in this group H. rizibilis (previously placed in the then O. catharinae species group) and Hyla ranki.…”

The hylid frog genus Scinax ranges from southern Mexico to eastern Argentina. The 84 recognized species are currently arranged in five groups: the Scinax rubra, Scinax rostrata, Scinax catharinae, Scinax staufferi, and Scinax perpusilla species groups. Although a few species groups are distinctive, compelling evidence of monophyly is lacking for three groups, and their interrelationships remain virtually unknown. With the objective of testing the monophyly of the species groups and exploring their interrelationships, a cladistic analysis was performed, employing 86 characters from osteology, myology, adult and larval external morphology, reproductive biology, and karyotypes taken from 36 representative species of the five species groups plus eight outgroup taxa. The analysis of the resulting data matrix shows moderately well-supported (as assessed through Bremer support and parsimony jackknifing) S. catharinae and S. rostrata species groups. The S. staufferi species group is polyphyletic, as currently composed, given that some of its species are nested within the S. catharinae species group. The only representative of the S. perpusilla species group is the sister species of the S. catharinae species group. Although weakly supported, the representatives of the S. rostrata and S. staufferi species groups are nested, separately, within the S. rubra species group. In order to have a taxonomy consistent with these results, it is proposed not to recognize the S. rubra group but to recognize a more inclusive rubra clade that includes all studied exemplars of the former S. rubra group, plus some of the S. staufferi group and all of the S. rostrata group. Similarly, a catharinae clade is recognized, within which all studied exemplars of the S. catharinae group (that now includes Scinax berthae and Scinax agilis) and the one studied representative of the S. perpusilla group are included.

“…Almeida and Cardoso (1985) did not question the presence of a sperm with double tail, though they commented that the flagella moved like a single element. Andrade and Cardoso (1987) defined the Ololygon rizibilis species group (as Hyla) by the presence of a laterally expanded vocal sac. noticed that some species of Ololygon (based on representatives of the then O. catharinae, O. staufferi, and O. rubra species groups) had the ability to bend their thumbs and first toes backward and suggested that this could be a synapomorphy of the genus.…”
