Despite the impressive growth of knowledge on the phylogenetic systematics of dart-poison
frogs and their relatives (Dendrobatoidea) over the past decade, many problems remain to …

We describe a new species of litter frog from western Brazilian Amazon previously referred
to as Allobates femoralis (Boulenger 1883). The new species is allopatric to A. femoralis and …

Female fecundity is an important selective force leading to female-biased sexual size
dimorphism (SSD) in frogs. Because anurans exhibit diverse reproductive modes, we …

The small size, low vagility, territoriality, and reproductive mode of some Amazonian frogs
undermine the wide geographical distribution assigned to them. Species with these features …

We describe a new species of Allobates from the south of eastern Amazonia, Brazil. This
species inhabits fluvial springs and the banks of small streams in terra-firme forests along …

We describe Allobates grillisimilis from the northwestern region of the Rio Madeira—Rio
Tapajós interfluve, state of Amazonas, Brazil. The new taxon is characterized by its small …

Numerous species of aromobatid frogs in the genus Allobates from the Amazonian region of
Brazil have been described in recent years. Herein, we describe a new Allobates from the …

The small nurse frogs of the genus Allobates (Anura, Aromobatidae) represent one of the
most challenging taxonomic issues of the Neotropics. During several amphibian surveys in …

Few studies have focused on the diverse fauna of southwestern Brazilian Amazonia. This
region, spared from large-scale human occupation until the second half of the twentieth …

Acoustic parameters often usefully supplement the classic morphological approaches used
to discriminate between similar species of frogs, and thus provide better assessments about …
