Dendrobatinae Explained

Dendrobatinae is the main subfamily of frogs in the family Dendrobatidae, the poison dart frogs of Central and South America, found from Nicaragua to the Amazon basin in Brazil.[1]

Description

Dendrobatinae are generally small frogs; Andinobates minutus is as small as 13mm16mm in snout–vent length. Many species are brightly colored and all are toxic. Alkaloids in Phyllobates are particularly potent.[2]

All species are presumed to show parental care, often by the male. However, some species show biparental care (Ranitomeya), whereas in Oophaga only females care for the tadpoles, feeding them with eggs, their only source of nutrition.[2] The males are responsible for protecting the eggs from predation and keeping the eggs from drying out by urinating on them.[3]

General

There are eight[1] [2] or seven[4] genera in this subfamily:

Adelphobates Grant, Frost, Caldwell, Gagliardo, Haddad, Kok, Means, Noonan, Schargel, and Wheeler, 2006
Andinobates Twomey, Brown, Amézquita, and Mejía-Vargas, 2011
Dendrobates Wagler, 1830
Excidobates Twomey and Brown, 2008
Minyobates Myers, 1987
Oophaga Bauer, 1994
Phyllobates Duméril and Bibron, 1841 P. lugubris species group

P. bicolor species group

Ranitomeya Bauer, 1986

The most specious genera are Ranitomeya (16 species) and Andinobates (13 species).[1] Dendrobates used to be much larger but currently contains only five species, having had most of its species split off into genera erected later.[6]
