RESUMO

We describe the breeding biology and the advertisement call of the horned leaf-frog, Proceratophrys appendiculata (Günther, 1873) in the Parque Nacional da Serra dos Órgãos, municipality of Teresópolis. The reproductive period of P. appendiculata is short and is associated with the end of the winter and the beginning of the spring, when males call night and day under large rocks in sandy bottom rock streams. The amplexus is axillary and one female laid about 656 viscous eggs. The advertisement call of P. appendiculata is unique among congeners. The call lasts approximately two seconds, with about 85 pulses/call at a rate of 45 pulses/s and frequency around 0.620 kHz. It is one of the longest calls and lowest in dominant frequency. Moreover, the call of P. appendiculata is characterized by the greatest number of pulses so far registered, reaching 129 pulses in a single call.
