Distribution

Originally described from Manu National Park, Peru, A. macero is now known to occur some 240 km to the north-northeast, on the Rio Alto Purus, and the drainage system of the Ucayali. Although thought to be a lowland species, it was recently discovered as high as 850 m by a research team working in the area. Field work in 2007 revealed another outlying population of A. macero near La Merced, Peru, at an elevation of approx. 1500 m. View type locality in Google Maps.

Natural history

Adults were found to be near small streams during the end of the dry season, and presumably move out into the general forest during wetter times of the year. Tadpoles are thought to be deposited in streams as opposed to standing water.

Conservation status

This species has a large range, much of which is in a national park, and is therefore at minimal risk of population declines.

Notes

Sister to a clade containing A. rubriventris plus A. altamazonica.
