***Colostethus*** is a [genus](/source/Genus) of [poison dart frogs](/source/Poison_dart_frog) native to Central and South America, from Panama south to Colombia, Ecuador, and northern Peru. Their common name is **rocket frogs**,[1] but this name may refer to frogs in other genera and families, following the taxonomic revision of the genus in 2006.[2]

## Taxonomy

Formerly, the genus *Colostethus* was found to be "rampantly [nonmonophyletic](/source/Polyphyly)" in the taxonomic revision of [poison dart frogs](/source/Poison_dart_frog) published in 2006.[3] Before the revision, it had 138 species, but this was reduced to 18 species, after species of the former *Colostethus* were distributed among eight genera in two families, that is, in Dendrobatidae and in the newly established family [Aromobatidae](/source/Aromobatidae) (e..g., *[Anomaloglossus](/source/Anomaloglossus)*). Within Dendrobatidae, many former *Colostethus* species were moved to *[Hyloxalus](/source/Hyloxalus)*, while three were moved to the new genus *[Silverstoneia](/source/Silverstoneia)*.[3] Nevertheless, *Colostethus* is still considered [paraphyletic](/source/Paraphyletic) because some *Colostethus* are more closely related to *[Ameerega](/source/Ameerega)* than to other *Colostethus*.[1]

## Description

[Dorsal](/source/Dorsum_(anatomy)) colouration is cryptic, brown. A pale oblique lateral stripe is present (but may be broken or incomplete). Dorsal skin is granular posteriorly. In adult males, third finger is swollen.[3]

There are currently 12 species in this genus:[1]
