New synonymy. _Hyla cabrerai_ Cochran and Goin, 1970:215 [Holotype.--USNM 152759 from Cano Guacaya, tributary of lower Rio Apoporis, Comisaria Amazonas, Colombia; Isadore Cabrera collector]. New synonymy. _Justification of Synonymy._--Boulenger (1882:362) listed 11 specimens in his description of _Hyla buckleyi_. We have examined all of these and conclude that one (BMNH 1947.2.13.42) is _O. leprieurii_. Cochran and Goin (1970:213) restricted the type locality to Canelos, Provincia Pastaza, Ecuador; we here select BMNH 1947.2.13.44 from that locality as the lectotype. This specimen is a male having a snout-vent length of 37.9 mm; the diameter of the tympanum is 3.5 mm, 81.4 percent of the diameter of the eye. The type series, exclusive of BMNH 1947.2.13.42 (=_O. leprieurii_) consists of six males having snout-vent lengths of 37.9-44.6 (mean 40.4) mm, and four females having snout-vent lengths of 50.0-53.9 (mean 51.5) mm. The dorsum in the males bears a mixture of large and small tubercles, whereas the dorsum in females is nearly smooth. The skin on the flanks, especially the axilla, is areolate. The coloration consists of a creamy tan ground color with irregular reddish brown markings on the back and broad transverse bars on the limbs. The dorsal markings are narrowly bordered by creamy white; those on the back consist of an interorbital bar and a pair of longitudinal marks beginning in the scapular region and usually diverging posteriorly in the sacral region or converging into a broad median blotch. One specimen has a middorsal creamy white stripe from the tip of the snout to the vent. In all of the types large dark brown spots are present on the flanks and posterior surfaces of the thighs. The ventral surfaces are pale creamy tan with or without diffuse brown spots on the throat and chest.
