Oreobates is a genus of frogs in the family Strabomantidae.[1] Most species were formerly in the genus Ischnocnema, but were moved to this revalidated genus following a 2006 revision.[2] Its sister taxon is Lynchius.[1]
These frogs are found in the lower slopes of the Andes into the upper Amazon Basin from Colombia south to northern Argentina and east into western Brazil.[1]
A 2021 phylogenomic study found that Oreobates comprises two main clades: a northern group (Colombia–Peru) and a southern clade (Bolivia–Argentina), largely segregated by the elevational gradient.[3] The study also found that highland species are less genetically diverse than their lowland relatives and carry more nonsynonymous mutations — a pattern consistent with historically smaller, more isolated populations and reduced efficacy of natural selection in mountain habitats.
