Taxonomic Notes: Until recently, Hyla wrightorum was regarded as a synonym of Hyla eximia, but Duellman (2001) recognized H. wrightorum as a distinct species.

The genus Dryophytes was resurrected from synonymy under Hyla by Duellman et al. (2016) and this species was transferred from Hyla to Dryophytes.
