Resumo

Ischnocnema parva is a small species that occurs in the leaf litter within the Atlantic Forest in southeastern Brazil. The advertisement call of this species was described in the early 90's based on an undefined number of males from Estacao Biologica da Boraceia in the municipality of Salesopolis, state of Sao Paulo. In this study, based on data from four localities in two Brazilian states, we re-describe the advertisement call of I. parva which consists of a single type of pulsed note emitted sporadically with its fundamental frequency peaking at about 2000 Hz and its dominant frequency peaking at about 4000 Hz. The calls of males from two localities have a higher pulse rate and longer interpulse interval. Compared to our data, the call previously described in literature has a higher pulse rate and lower dominant frequency. In addition, we interpret that the species call has a harmonic structure and a distinct amplitude modulation from the previously reported. (AU)
