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 and2008-2009). Clutches were raised in captivity (artificial ponds) to analyse the developmentof embryos and tadpoles. Breeding sites were represented by streams andtheir backwaters, as well as temporary and permanent ponds of varying sizes.Operational sex ratio was male-biased varying between 0.154 and 0.25. Acousticactivity started about 8-10 pm and ended between 2 and 4 amthe next day. Distanceamong calling males was approximately three metres. Male satellite behaviour wasobserved. Amplexus attempts among males were common. Release calls were structurallysimilar although shorter than advertisement calls. Courtship and formationof amplexus were documented.
