Calls of Boana latistriata (Caramaschi & Cruz, 2004) (Amphibia, Anura, Hylidae), an endemic tree frog from the State of Minas Gerais, Brazil

Bioacoustical data are useful for studying amphibians, especially their conservation, taxonomy, and evolution, among others. Of the 12 species of the Boana polytaenia clade, only B. buriti and B. latistriata have no published information about their advertisement calls. We recorded four males of B. latistriata in its type locality at Parque Nacional do Itatiaia, south-eastern Brazil. We used a Roland R26 digital recorder with a Sennheiser ME-67 microphone and analysed the recordings using the Raven Pro 1.5 software. We recorded two different types of calls (call A and call B). Both were composed of one pulsed note and presented a slightly ascending-descending frequency modulation. Call A was more frequent, having durations between 0.042 and 0.093 s with the dominant frequency ranging from 3375.0 to 3937.5 Hz, and was composed of 11 to 21 pulses separated by intervals that were not fully silent. Call B had durations between 0.711 and 1.610 s, with dominant frequency from 3281.2 to 3750.0 Hz, and was composed of 11 to 29 pulses separated by fully silent intervals. Among the B. polytaenia clade, the calls of B. latistriata are more similar to those of B. bandeirantes, B. beckeri, B. polytaenia, and B. aff. beckeri. The calls of B. latistriata differ from these species in its lower dominant frequency. Boana latistriata present a short, single-note call with a lower pulse period (call A) and a long call with higher pulse period (call B), which differ from the other species of the clade. The coefficients of variation for the various bioacoustical attributes were calculated within- and between-males and these have been discussed. We also report a fight event between two males of B. latistriata. This is the first report of a fight in members of the B. polytaenia clade

Amphibia, Anura, Hylidae, Sphaenorhynchus prasinus Bokermann, 1973: First record of the genus and species for the State of Alagoas, Brazil

Sphaenorhynchus prasinus is a medium sized frog belonging to the genus. The geographic distribution comprises southeast and northeast of Brazil. Herein, we report for the first time the occurrence of Sphaenorhynchus prasinus and of the genus is the State of Alagoas

First record of Scinax tripui Lourenço, Nascimento and Pires, 2010 (Amphibia: Anura: Hylidae) from Espírito Santo state, Brazil

Scinax tripui is a medium sized frog that belongs to the Scinax catharinae clade. We provide a new record of Scinax tripui from Serra de Torres, Espírito Santo state, southeastern Brazil. This is the first record outside the specie’s type locality (Ouro Preto, Minas Gerais) and the first record from the state of Espírito Santo

Updated list of anurans from Floresta Nacional Mário Xavier, Seropédica, Rio de Janeiro, Brazil: changes from 1990 to 2012

The Floresta Nacional Mário Xavier (FNMX) is a reserve located in the Municipality of Seropédica, State of Rio de Janeiro, southeastern Brazil. It is an area with intense anthropic activity and is one of the last remaining forests of the Baixada Fluminense. An inventory of the anurans of the FNMX was performed and the results compared with those of a previous species list for the area. Thirteen excursions were conducted, totaling more than 416 hours of sampling effort. Twenty-six species belonging to five families were found: Bufonidae (one species), Hylidae (15 species), Leptodactylidae (six species), Microhylidae (three species) and Phyllomedusidae (one species). Six species on the previous list were not found in this study. Sphaenorhynchus planicola is a new record for the area. Two species are endangered: Chiasmocleis lacrimae and Physalaemus soaresi, the latter being considered critically endangered by the List of Brazilian Fauna Threatened with Extinction
