The Anomaloglossinae are a subfamily of frogs from the family Aromobatidae . They include two genera and 30 species, the range of which is in the northwest and north of South America .

features

Diagnostic features are found particularly on the fingers and toes. A seam is formed on the pre-axial (inner) side of the second and third fingers and the first toe, and on the post-axial (outer) side of the fifth toe. On the postaxial side of the first toe, the webbing is more developed than on other members of the family. The adhesive disc on the second toe is moderately developed, stronger than that of closely related taxa. The metatarsal fold, a skin seam that runs from the outside of the fifth toe to the tarsus, is strongly developed. The belly of the males is irregularly spotted or weakly and diffusely spotted.

Geographical distribution

The Anomaloglossinae are found mainly east of the Andes in the western Amazon and the Orinoco catchment area in Venezuela , Guyana , Suriname , French Guiana and the northeast of Brazil . In many species, the distribution is limited to Tepuis . In the east the distribution area extends into the northwestern Mata Atlântica . In Colombia some representatives of Anomaloglossus occur on the Pacific slopes, as well as the representatives of Rheobates on both sides of the Andes.

Way of life

Anomaloglossinae are diurnal and terrestrial inhabitants of the tropical rainforest . The tadpoles grow in bodies of water on the ground or in Phytotelmata on bromeliads . With the exception of Anomaloglossus stepheni , adult males carry them on their backs.

Hazard and protection

The inventory data is poorly explored for many types of anomaloglossus . In the Red List of Threatened Species of IUCN most species are listed, with the risk levels of Least Concern (Least Concern) to Vulnerable (Endangered) rich. For example, insufficient data are available for Rheobates pseudopalmatus , Rheobates palmatus has the classification Least Concern (not endangered).

Systematics and taxonomy

The subfamily Anomaloglossinae and the genera summarized in it were newly established together with the family Aromobatidae . The Anomaloglossinae arise from a basal branch of the Aromobatidae, while the other two subfamilies Aromobatinae and Allobatinae are more closely related. There are 31 species in two genera:

species

Anomaloglossus beebei from Guyana
Anomaloglossus stepheni from Amazon, Brazil

Status: July 7, 2020

Some species of the genus Anomaloglossus have been separated into the new genus Ectopoglossus in the subfamily Hyloxalinae , family poison dart frogs (Dendrobatidae):
