Data from: Notes on the acoustic repertoire of Melanophryniscus klappenbachi Prigioni & Langone, 2000

The genus Melanophryniscus Gallardo, 1961 currently comprises 25 recognized species (Frost 2012) arranged in three (Cruz & Caramaschi 2003) to four species groups (Cespedez & Motte 2001, quoted by Maneyro et al. 2008) on the basis of morphological characters. 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 other members of the group.

墨蟾属（Melanophryniscus Gallardo, 1961）目前已确认包含25个有效物种（Frost, 2012），依据形态特征可划分为3个（Cruz & Caramaschi, 2003）至4个物种组（Cespedez & Motte, 2001，引自Maneyro等, 2008）。
星氏墨蟾物种组（Melanophryniscus stelzneri species group）目前包含9个物种，分别为：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）以及M. stelzneri（Weyenbergh, 1875）。
截至目前，该物种组中仅有4个物种的宣鸣（advertisement call）被正式记述，分别为M. atroluteus、M. dorsalis、M. krauczuki与M. montevidensis（Kwet等, 2005；Baldo & Basso, 2004）。
本研究记述了M. klappenbachi的求偶鸣唱（courtship call）与遇险鸣唱（distress call），并将其与该物种组内其他类群的鸣唱进行了对比分析。
