Anurans emit a variety of acoustic signals in different behavioral contexts during the breeding season. The release call is a signal produced by the frog when it is inappropriately clasped by another frog. In the family Phyllomedusidae, this call type is known only for
Pithecophusayeaye
. Here we describe the release call of four species:
Phyllomedusabahiana
,
P.sauvagii
,
Pithecopusrohdei
, and
P.nordestinus
, based on recordings in the field. The release calls of these four species consist of a multipulsed note. Smaller species of the
Pithecopus
genus (
P.ayeaye
,
P.rohdei
and
P.nordestinus
), presented shorter release calls (0.022–0.070 s), with higher dominant frequency on average (1508.8–1651.8 Hz), when compared to the bigger
Phyllomedusa
(
P.bahiana
and
P.sauvagii
) (0.062–0.107 s; 798.7–1071.4 Hz). For phyllomedusid species, the release call might indicate a phylogenetic signal, because species of the same genus have similar acoustic traits.
