Ameerega flavopicta is a dart-poison frog (Dendrobatidae) widely distributed throughout rocky habitats in the Brazilian states of Minas Gerais, Goiás, Tocanthins, Pará, and Maranhão. Here we repoert for the first record of a dendrobatid frog in the State of São Paulo, Brazil, based on individuals of A. flavopicta found in the Municipality of Pedregulho, and also describe the advertisement calls of a male from this population. A taxonomic discussion is provided.

Black Color

Poison dart frogs provide classic examples of warning signals: potent toxins signaled by distinctive, conspicuous coloration. We show that, counterintuitively, the bright yellow and blue-black color of Dendrobates tinctorius (Dendrobatidae) also provides camouflage. Through computational modeling of predator vision, and a screen-based detection experiment presenting frogs at different spatial resolutions, we demonstrate that at close range the frog is highly detectable, but from a distance the colors blend together, forming effective camouflage. This result was corroborated with an in situ experiment, which found survival to be background-dependent, a feature more associated with camouflage than aposematism. Our results suggest that in D. tinctorius the distribution of pattern elements, and the particular colors expressed, act as a highly salient close range aposematic signal, while simultaneously minimizing detectability to distant observers.
