This new species is distinguished from other species of Dendropsophus by its small size (SVL 18.7&ndash;21.1 mm in adult males and 19.6&ndash;23.2 mm in females); in life, dorsal ground coloration brown, with two anterior parallel and straight, dark brown stripes and a middorsal sacral stripe; and lateral limits of dorsal coloration above tympanum. In addition, the new species differs from all other species of the D. rubicundulus group (along with D. anataliasiasi) by having a composite advertisement call, i.e., a series of calls consisting of two call types. In a phylogenetic tree based on 494 bp of the 16S mitochondrial gene, four species of Dendropsophus, D. cruzi, D. juliani, and D. sanborni and one candidate species, D. juliani A, are positioned within the rubicundulus species group which poses questions on the monophyly of this group as well as its morphological definition. The occurrence of both single and composite calls in the D. rubicundulus group suggests future studies on the call evolution in that group as well as the whole genus.</p>

We tested the hypothesis that M. temminckii uses the clutter rejection strategy in cluttered environments and determined whether the echolocation calls of this species show large-scale geographic variation. We recorded echolocation calls of 10 individuals of M. temminckii using 4 treatments with different degrees of clutter. We compared individuals recorded in Venezuela with individuals recorded in Brazil to verify geographic variation in calls. In the cluttered environments, M. temminckii emitted short downward frequency-modulated calls with short pulse intervals. In the uncluttered environments, M. temminckii emitted long upward frequency-modulated calls with longer intervals and shorter bandwidth. The decreased pulse duration and interval in cluttered environments support the hypothesis that M. temminckii uses the clutter rejection strategy. Additionally, we found that in Brazil, M. temminckii emits shorter calls with higher minimum frequency compared with bats recorded in Venezuela, indicating large-scale geographic variation, probably because of environmental factors.</p>
