Ranitomeya is a genus of dart poison frogs found in Panama and South America south to Peru and Brazil, possibly into Bolivia.

Taxonomy

In 2006 Grant et al. revised the systematics of poison dart frogs and placed many species formerly classified in the genera Dendrobates, Minyobates and Phyllobates in Ranitomeya. In 2011 Brown and colleagues, following other scientists who assumed the existence of two distinct clades in Ranitomeya, erected the genus Andinobates for 12 species of Ranitomeya.

Ranitomeya and Andinobates frogs can be distinguished from those in genera such as Dendrobates in that they are generally smaller, have more than two colors, and seem to glitter if viewed from certain angles. Ranitomeya is widespread in the Amazon basin, whereas Andinobates species are found only in the northern Andes down to Central America.

Description

Adults measure no more than 21 mm (0.83 in) in snout–vent length and are typically brightly colored, often with bright yellow, red, or green dorsum that can be uniform in color or with stripes or dots. Also the throat has distinctive color, usually yellow, orange or red. Dorsal skin is smooth or weakly granular. The head is narrower than the body. Fingers and toes bear discs, with those on the fingers being large. Some species, such as R. Variabilis, in the genus exhibit tadpoles transport and cannibalistic behavior.

Threats

Many Ranitomeya species are threatened by habitat loss and collection for the pet trade.
