Scientists made this genus in 2005 after looking closely at all the frogs in Hylidae. The frogs in "Charadrahyla" are those that used to be in the "Hyla taeniopus" group as defined by in 1970. The genus was originally made using molecular markers and no morphological synapomorphies, meaning that scientists only used the frogs' genes to tell whether they should be in this group. They did not use what the frogs looked like or how their bodies worked. The closet related group to "Charadrahyla" is the genus "Megastomatohyla".
