The advertisement call of Dendropsophus pseudomeridianus (Cruz, Caramaschi & Dias) (Anura: Hylidae).

چکیده
The advertisement call plays a fundamental role in anuran reproduction (Duellman & Trueb 1994; Wells 2007). Some species that may be confused morphologically with each other can be distinguished by vocalization (Pombal et al. 1995). It is the case of Dendropsophus pseudomeridianus, which is phenotypically very similar to D. berthalutzae (Bokermann), D. branneri (Cochran), D. decipiens (Lutz), D. haddadi (Pombal & Bastos), D. meridianus (Lutz) and D. oliveirai (Bokermann). Herein, we present the first quantitative description of the advertisement call of D. pseudomeridianus and compare it with the advertisement call of morphologically similar species of the D. microcephalus group. We analyzed 183 calls of three individuals from the Reserva Particular de Patrimônio Natural Campo Escoteiro Geraldo Hugo Nunes in the municipality of Guapimirim, State of Rio de Janeiro (22° 34’ 37” S and 43° 01’ 50” W, 23 m a.s.l.), at approximately 70 km from the type locality. The recordings were made at a sampling rate of 44.1 kHz and 24 bits using a Tascam DR-07 digital recorder and a Sennheiser ME67 microphone, at an air temperature of 25°C. The analyses were performed using the program Raven Pro 1.4 from The Cornell Lab of Ornitology (Bioacustic Research Program 2011). Technical terms and definitions follow Littlejohn (2001). Numerical call parameters are given as range followed by mean ( ) ± standard deviation (SD), mode (Mo) and number of samples (n). Voucher specimens are

The analysis of the external morphology variation in Crossodactylus bokermanni, C. trachystomus, and in unidentified specimens from 14 localities along the southern region of the Serra do Espinhaço, state of Minas Gerais, Brazil, revealed that all of these forms belong to the same taxon. Crossodactylus bokermanni is considered a junior synonym of C. trachystomus, whose holotype is redescribed a...

We describe a new species of the Dendropsophus leucophyllatus Group from the Atlantic Forest of the southern region of State of Bahia, Brazil. It can be distinguished from all species of the D. leucophyllatus Group on the basis of morphological characters (especially its unique dorsal pattern and snout in dorsal view), advertisement calls and divergence in mitochondrial DNA gene sequences. The ...

We describe Dendropsophus ozzyi sp. nov., a new species of treefrog, tentatively included in the Dendropsophus microcephalus Group and most notably diagnosed by the presence of pointed fingers and an advertisement call with a very high dominant frequency. The new species is known from three localities in the Brazilian Amazon forest, two on western State of Pará and one (the type locality) in ea...

We describe a new treefrog species of Dendropsophus collected on rocky outcrops in the Brazilian Atlantic Forest. Ecologically, the new species can be distinguished from all known congeners by having a larval phase associated with rainwater accumulated in bromeliad phytotelms instead of temporary or lentic water bodies. Phylogenetic analysis based on molecular data confirms that the new species...
