Play Ameerega hahneli Call
Ameerega hahneli ranges throughout much of South America. In Peru, this species can be found in most lowland rainforest throughout the entire country, and in the Andean foothills near Tarapoto and Cusco.
This small, diurnal frog appears to reach peak activity just before dusk. They can be found calling among the leaf litter, where they forage and court throughout the year. Tadpoles are transported to small puddles and other non-flowing water bodies.
Due to the large range and low market demand, this species is not of major conservation concern.
Roberts et al. (2006) found this species to be paraphyletic and formed two distinct clades, one with a montane distribution in San Martin, Peru, and the other distributed throughout the Amazonian lowlands from southern Peru to Iquitos in the north. This species was recently restricted by Twomey and Brown (2008) to exclude frogs from the upper Huallaga drainage, which are now referred to as A. altamazonica. Different analytical methods change phylogenetic topologies with regard to the placement of hahneli, though A. macero and A. pulchripecta appear to be closely related species.
Thanks to the excellent photo by Jason Brown comparing A. hahneli and Allobates femoralis, distinction between the two is made somewhat easier. One major difference is that hahneli has a blue belly, whereas the belly of femoralis is marbled black and white. Dorsal coloration varies from chocolate brown to black.
