Phylogenetic relationships of the poorly known treefrog Boana hobbsi (Cochran amp; Goin, 1970) (Anura: Hylidae), systematic implications and remarks on morphological variations and geographic distribution.

Boana hobbsi is a poorly known hylid frog currently placed within the Boana punctata group. Yet, morphological, ecological and bioacoustic traits do not support this placement, with no molecular data being available to date to test this hypothesis. Based on newly collected mitochondrial DNA sequences, morphological data review and field observations, we provide new insight into the phylogenetic relationships, morphological variations and geographic distribution of B.

Description of the tadpole of Dendropsophus haraldschultzi (Bokermann, 1962) (Anura: Hylidae), with comments on reproductive biology.

The genus Dendropsophus Fitzinger contains 108 recognized species (Frost 2020) distributed in nine species groups according to Faivovich et al. (2005). However, recent phylogenetic analysis recognized the presence of nonmonophyletic groups (e.

On Rhinella gildae Vaz-Silva, Maciel, Bastos Pombal 2015 (Anura: Bufonidae): Phylogenetic relationship, morphological variation, advertisement and release calls and geographic distribution.

Anurans in the Rhinella margaritifera group have a long history of taxonomic confusion, mainly by morphological similarity between species and lack of acoustic and genetic data for many of the 19 described species. Herein, we presented data for Rhinella gildae based on recently collected specimens from its type locality. We provide patterns of morphological variation, measurements, advertisement and release calls and infer the phylogenetic position of R.

Integrative overview of the herpetofauna from Serra da Mocidade, a granitic mountain range in northern Brazil.

The Brazilian mountain ranges from the Guiana Shield highlands are largely unexplored, with an understudied herpetofauna. Here the amphibian and reptile species diversity of the remote Serra da Mocidade mountain range, located in extreme northern Brazil, is reported upon, and biogeographical affinities and taxonomic highlights are discussed. A 22-days expedition to this mountain range was undertaken during which specimens were sampled at four distinct altitudinal levels (600, 960, 1,060 and 1,365 m above sea level) using six complementary methods.

A new species of from the Purus-Madeira interfluve, Brazilian Amazonia (Anura, Hylidae).

A new tree frog species of the genus from the interfluve between the Purus and Madeira rivers, Brazilian Amazonia, is described and illustrated. The new species is diagnosed by medium body size, snout truncate in dorsal view, ulnar and tarsal tubercles absent, nuptial pads poorly developed, skin on dorsum shagreen, dorsum light brown with dark brown spots and markings, white groin with black spots, anterior and posterior surfaces of thighs black, and iris bright orange. The advertisement call consists of a single short note, with 16-18 pulses and dominant frequency at 1572-1594 Hz.
