Abstract
Although comparative studies of anuran ontogeny have provided new data on heterochrony in the life cycles of frogs, most of them have not included Colombian species. Using different staining techniques, we describe the cranial and poscranial elements development in two hylid species, Scinax ruber and Dendropsophus labialis, providing new data for more comprehensive ontogenetic studies in Neotropical frogs. We examined specimens from Gosner stages 25 to 45. We found differences in the infrarostral and suprarostral cartilages, optic foramen, planum ethmoidale, and the gill apparatus. In the ossification sequence, one of the first elements to ossify were the transverse process of spinal column and atlas in both species, and the parasphenoid in the skull. New descriptions of skeletal development and ossification sequences of larval stages of these two species, especially data concerning the postcranium, contribute with useful information for analysis of sequential heterochrony, because although the hylids are widely known, there are few works (15 of 700 species) about ossification sequence that include the whole skeleton.
