The Melanophryniscus stelzneri species group currently contains nine species, i.e. M. atroluteus (Miranda-Ribeiro, 1920), M. cupreuscapularis Céspedez & Alvarez, 2000, M. dorsalis (Mertens, 1933), M. fulvoguttatus (Mertens, 1937), M. klappenbachi Prigioni & Langone, 2000, M. krauczuki Baldo & Basso, 2004, M. montevidensis (Philippi, 1902), M. rubriventris (Vellard, 1947), and M. stelzneri (Weyenbergh, 1875). So far, advertisement calls of only four of these species have been described, i.e. those of M. atroluteus, M. dorsalis, M. krauczuki, and M. montevidensis (Kwet et al. 2005, Baldo & Basso 2004). Herein, we describe the courtship call and distress call of M. klappenbachi and compare it with the calls of ...
