Abstract
We provide detailed information on breeding sites, release call, satellite behaviour, courtship, and embryonic and larval development of Odontophrynus cordobae. Field observations were carried out during two breeding seasons (2004–2005 and 2008–2009). Clutches were raised in captivity (artificial ponds) to analyse the development of embryos and tadpoles. Breeding sites were represented by streams and their backwaters, as well as temporary and permanent ponds of varying sizes. Operational sex ratio was male-biased varying between 0.154 and 0.25. Acoustic activity started about 8–10 pm and ended between 2 and 4 am the next day. Distance among calling males was approximately three metres. Male satellite behaviour was observed. Amplexus attempts among males were common. Release calls were structurally similar although shorter than advertisement calls. Courtship and formation of amplexus were documented.
