Resumen:
The present study describes the reproductive biology of Argenteohyla siemersi
pederseni in a modified quebracho forest of Schinopsis balansae in northeastern
Argentina. Observations were made between January 2007 and March 2009 at El
Perichón, Corrientes Province, Argentina. Argenteohyla s. pederseni bred once
per year over a 3-day period in a semi-permanent pond during the first spring
rains in mid-September. Males called while floating on the water surface. The
advertisement call was short and repeated at regular intervals in relatively fast succession,
forming groups of multiple calls. Aggressive calls were evoked in two different
agonistic interactions. Eggs were black, laid in three-dimensional arrangements
interspersed within the submerged vegetation. Egg number per clutch ranged from
2638 to 8987. Tadpole redescription shows many differences and similarities with
previous descriptions. The reproductive biology of A. s. pederseni has several similarities
with another pond-dwelling casque-headed frog species.
