Abstract
The genus Haddadus currently consists of three species, after the recent transfer of Strabomantis aramunha to this genus (Amaro et al. 2013). In the original description the authors suggested H. aramunha may not vocalize (Cassimiro et al. 2008), a claim that was later refuted on the basis of field observations (Napoli et al. 2010). Herein we provide the first description of the advertisement call of H. aramunha along with some notes on its natural history.
