Bauer , 1986

The genus Ameerega belongs to the family of South American poison dart frogs , which are often referred to as poison dart frogs. The genus was established in 1986 by L. Bauer. The type species of the genus Ameerega is Ameerega trivittata .

features

The genus Ameerega belongs to the subfamily Colostethinae . It is characteristic of these that their back skin is not smooth and shiny, as is the case with most species of the subfamily Dendrobatinae . But while the dorsal skin of the other genera of the Colostethinae is irregularly littered with more or less clearly raised or conical small warts, which lie close together in the rear area of ​​the back and on the thighs and become sparse or absent towards the front, the skin is with the species of the genus Ameerega uniformly granular in structure. This feature also distinguishes the genus Ameerega from the genus Epipedobates , from which it was separated out after a complete revision of the poison dart frogs in 2006.

The first finger is longer than the second. The third finger is swollen in sexually mature males. During courtship , the female takes a crouched position in front of the male. The male clasps the head of the female when mating.

distribution

With a few exceptions, the genus Ameerega is native to the east of the Andes . Most species live in the lowlands, but some can be found up to 1400 m. Ameerega andina and Ameerega erythromos occur at moderate altitudes on the Pacific slopes of the Andes.

In Brazil , the frogs can be found from the states of Mato Grosso do Sul and Goiás to the north and north-west of the Amazon basin . In western South America they occur from Bolivia via Peru and Ecuador to Colombia and Venezuela. Ameerega maculata from Panama is only known from one type specimen .

species

Many species were placed in the genus Ameerega in 2006 when they were separated from the genus Epipedobates . As a result, a number of species were newly described, two were placed in the re-established genus Paruwrobates in 2017 , so that 31 species are now known.

As of April 13, 2018

Ameerega andina and Ameerega erythromos were placed in the re-established genus Paruwrobates in 2017 as Paruwrobates andinus (Myers and Burrowes, 1987) and Paruwrobates erythromos (Vigle & Miyata, 1980) . Ameerega maculata (W. Peters, 1873) is now in the genus Epipedobates as Epipedobates maculatus .
