Adelphobates quinquevittatus

Adelphobates quinquevittatus, the Rio Madeira poison frog, is a species of frog in the poison dart frog family Dendrobatidae. It lives in the Rio Madeira drainage of the southern Amazon Basin in Brazil and Bolivia. Many records made before 1990 were actually of a different frog, Ranitomeya ventrimaculata. Scientists have watched it on the leaf litter of tropical rainforests, and its known range includes protected parks such as Parque Estadual de Guajara-Mirim. The female lays her eggs on the leaf litter, and after they hatch the adults carry the tadpoles to water, for example in bromeliad plants or in the husks of Brazil nuts. The IUCN rates the frog as of least concern, though deforestation for agriculture, mining, fires and hydroelectric dams are the pressures it faces.
