Cochran and Goin (1970:211) based their description of _Hyla carri_ on one gravid female and stated: "A large _Hyla_ with the vomerine teeth in two ^^ shaped patches between the somewhat squarish choanae; reduced webs between the fingers; and a pattern of dorsal dark blotches bordered by light margins. The species is not similar to any other species known in Colombia. It is perhaps most closely related to _Hyla claresignata_ of Brazil, from which it can be differentiated by its more heavily spotted dorsum, larger tympanum, and lack of dark anal spots." Except for the inclusion of the name in checklists, _Hyla festae_ has not been mentioned in the literature since the original description. The wholesale synonymization of names, which, on the bases of their published diagnoses, seem to apply to distinctly different species, is possible with the application of uniform criteria to the types and series of other specimens. In measurements and proportions the type specimens of the nominal taxa all fall within the range of variation exhibited by a series of 18 males and 15 females from Provincia Pastaza, Ecuador, except the ratio of the diameter of the tympanum to that of the eye in the female holotype of _Hyla festae_. In that specimen the ratio is 0.574, whereas the ratio in the 15 females from Provincia Pastaza is 0.587-0.905 (mean 0.736). Ventral coloration is the most variable character among the types. The venter in the type of _Hyla festae_ is boldly spotted; it is distinctly spotted in _cabrerai_, uniform tan in _carri_, and tan, flecked, or spotted in the type series of _buckleyi_. The ventral coloration in series of specimens from Amazonian Ecuador encompasses that observed in all of the types, except that of _festae_, which has more ventral spotting than any other individual. The webbing on the hand usually excludes the penultimate phalanges of the fingers, but in some specimens from Amazonian Ecuador the webbing encompasses the proximal parts of the penultimate phalanges of the fingers. In a few of these specimens, the holotype of _festae_, and one paratype of _cabrerai_ the webbing extends to the middle of the penultimate phalanges of the third and fourth fingers. In the holotype of _cabrerai_ the webbing extends to the middle of the penultimate phalanges of the third and fourth fingers and to the base of the disc of the second finger.
