“…Os autores não deixam claro de onde obtiveram os registros nas listas de anfíbios e répteis, além daqueles destacados para o Plano de Manejo do Acaraí. Na lista de anfíbios, por exemplo, pelo menos nove espécies não ocorrem em São Francisco do Sul com base em trabalhos de taxonomia: Adenomera engelsi, Cycloramphus asper, C. duseni, Dendrophryniscus brevipollicatus, Ischnocnema guentheri, I. manezinho, Scinax perpusillus, Physalaemus maculiventris, Physalaemus spiniger (e. g. Canedo & Haddad, 2012, Lourenço et al, 2015, Carvalho et al, 2019, Cruz et al, 2019, de Sá et al, 2019. A confirmação do registro de espécies pode causar confusão na literatura, principalmente em se tratando de espécies com distribuição restrita, como é o caso de Cycloramphus asper, C. duseni e I. manezinho e pode prejudicar estratégias de conservação.…”

O conhecimento sobre a fauna local fornece subsídios chave para a elaboração de estratégias e implementação de práticas de conservação. O Ecossistema Babitonga (EB), no nordeste do estado de Santa Catarina, abriga uma importante diversidade biológica, ao mes-mo tempo em que sua economia crescente tem acelerado o uso dos recursos naturais da re-gião. O presente trabalho teve como objetivo fazer uma revisão do conhecimento existente sobre a herpetofauna não marinha desta região sobre a qual existem grandes lacunas de in-formação. Foi realizada uma revisão da literatura que reuniu 69 trabalhos a fim de listar as espécies com ocorrência comprovada ou provável ocorrência no EB. Foram identificadas 128 espécies da herpetofauna, quatro estão ameaçadas de extinção em Santa Catarina, sendo que 56 espécies de anfíbios e 31 espécies de répteis são endêmicas do Bioma Mata Atlântica e a espécie Brachycephalus actaeus é endêmica do EB. Esperamos que este trabalho sinalize a importância da região para a conservação da herpetofauna em Santa Catarina e incentive futuros trabalhos que contribuam para uma gestão sustentável de seu ecossistema.

“…Notwithstanding, taxonomical contributions for the genus Adenomera within this domain are seldom published. Before the recent description of A. kweti [15], the most recent taxonomical contribution for the genus in the Atlantic Forest domain was published a decade ago [16].…”

Taxonomists always have had intense discussions about how species should be delimited and recently many studies have used integrative approaches by combining molecular, morphological, and bioacoustic data. Although these studies are paramount for understanding species diversity, few of them actually formalize species delimitations to the final step of nomenclatural acts. Historically, the Neotropical frog genus Adenomera has been considered as a difficult taxonomic group because it comprises many morphologically similar species exhibiting high levels of intraspecific polymorphism. A recent work using molecular data shed light on the phylogenetic relationships within the genus and identified several lineages that may correspond to undescribed species but did not delimit species boundaries. In the Atlantic Forest, a clade formed by A. marmorata and two putative species (Adenomera sp. J and Adenomera sp. K) were identified. In this paper, we combine morphological, acoustic, and molecular data in order to evaluate species limits within this Atlantic Forest Adenomera clade. We provide a redescription of A. marmorata and restrict its type locality to the Tijuca Massif, in the Municipality of Rio de Janeiro, Brazil. Our results do not support A. marmorata and the two candidate species as diagnosable distinct species. Therefore A. marmorata corresponds to a species with pronounced morphological and acoustic variation in the genus and a complex phylogeographic structure.

“…Given these inconsistencies and the need to elucidate the acoustic parameters of S. squalirostris, we redescribe its advertisement call based on a new sample of topotypes. It is likely that S. squalirostris may comprise a species complex across its presumptive range (Pombal et al 2011, Faria et al 2013; thus, it is important to redescribe and authenticate its advertisement call, because vocalizations can be a key to the identification of cryptic diversity among frogs (e.g., Nunes et al 2012, Caminer and Ron 2014, Ron et al 2018, Carvalho et al 2019. To determine if there is inter-populational variation in advertisement calls, we report call data of a population from the Poços de Caldas Plateau in the Mantiqueira Range in the state of Minas Gerais (MG).…”

Reassessment of the advertisement call of topotypic Scinax squalirostris (Anura: Hylidae), with an acoustic evaluation of its occurrence in the Serra da Mantiqueira, southeastern Brazil. Scinax squalirostris (Lutz, 1925) is thought to occur along a broad range in South America. The values reported for calls of topotypes differ substantially among studies. Because vocalizations often play a key role in uncovering cryptic diversity, the call of S. squalirostris is herein redescribed based on a new sample of topotypes. The call of a population from Poços de Caldas, Minas Gerais state, is also described. Topotypic advertisement calls have a dominant frequency between 3970 and 4125 Hz; 13–15 notes emitted at a rate of 24–27/s; call rate of 67/min and duration of 0.52–0.61 s; mid-call notes having 6 or 7 well-defined pulses, and an intra-note pulse rate of 223–266/s. Calls of the Poços de Caldas population have dominant frequency between 4083 and 4358 Hz; 15–18 notes emitted at a rate of 32–34/s; call rate of 64/min and duration of 0.46–0.56 s; mid-call notes having 6 or 8 well-defined pulses, and an intra-note pulse rate of 252–312/s. The advertisement calls of these populations have some differences with each other, and are promptly distinguished from calls of morphologically similar species. Our data to topotypes are inconsistent with some previously reported. A more detailed study of the population from Poços de Caldas is required, and more marked differences may be found in populations more distant from type locality of S. squalirostris.
