Vocal repertory of Scinax littoreus (Anura: Hylidae) with comments on the advertisement call of the Scinax perpusillus species group

The Scinax perpusillus species group consists of thirteen bromeligenous treefrogs, of which only six have had their acoustic parameters appropriately described. In this work, we present the vocal repertory of Scinax littoreus (Peixoto, 1988) based on recordings obtained from three different populati...

Summary:The Scinax perpusillus species group consists of thirteen bromeligenous treefrogs, of which only six have had their acoustic parameters appropriately described. In this work, we present the vocal repertory of Scinax littoreus (Peixoto, 1988) based on recordings obtained from three different populations in the state of Rio de Janeiro, Brazil. Based on our observations we suggest that the vocal repertory of S. littoreus is composed of two distinct types of calls. The call named type A, which corresponds to a long series of multipulsed notes, is likely to have a mating function. This type of call is similar to that reported for Scinax arduous Peixoto, 2002, Scinax peixotoi Brasileiro, Haddad, Sawaya & Martins, 2007, and Scinax perpusillus (Lutz & Lutz, 1939). However, the type A call of S. littoreus is nonetheless readily distinguishable from the comparable call observed in other congeneric species. The call named type B, which exhibits a multipulsed structure, presumably has an aggressive function. We observed that different types of calls could be emitted alone or combined according to the social context. Additionally, we discuss problems involving comparisons of call parameters among species belonging to the S. perpusillus species group, provide an updated geographic distribution map, discuss the conservation status of the included species, and emphasize the importance of acoustic data for the recognition of species groups within Scinax.
