Strabomantidae

The Strabomantidae, sometimes called cloud forest landfrogs, are a family of frogs native to South America.

These frogs lack a free-living larval stage and hatch directly into miniature "froglets".

[1][2] This family includes Pristimantis, the most speciose genus of any vertebrate.

[3] Based on molecular dating, the Holoadeninae in particular appears to have originated in the Eocene.

[4] However, the lack of Holoadeninae fossils and limited nucleotide data ambiguates the results, by the authors' admission.
