Abstract

Many aspects about the reproduction of Melanophryniscus stelzneri stelzneri were estudied: environmental conditions in which reproduction occurs, pre and postreproductive adult behaviour, oviposition, larval developement, tadpole habits and metamorphosis. An anatomic description of the larva was also realized. Most of the observed behaviours are usual in argentinian anurans. The tadpole is tiny and typically lentic- bentonic. The most conmon queratodontic formula is 2 / 3. The time of metamorphosis is affected by water availability. A decreasing level of water accelerates the development.
