            Abstract We describe the internal oral morphology and chondrocranial anatomy forBoana crepitanstadpoles, and compare them with available descriptions for other species in the subfamily Cophomantinae. Among species of theBoana fabergroup, the chondrocranial anatomy has been reported only for one species internal oral morphology and cranial anatomy are similar to other described species ofBoanaand Cophomantinae.B. crepitanslacks unique features in the oral cavity and chondrocranium that would distinguish it from other congeneric species. We identify six characters from the internal oral anatomy of tadpoles unique for Cophomantinae. In addition,Boanahas infralabial papillae projections, buccal floor arena papillae, and lateral ridge papillae projections shorter than those described forAplastodiscusandBokermannohyla.more » « less

            Vences, Miguel (Ed.)The Neotropical microhylid genus Synapturanus was represented by only three species for almost five decades and remains poorly known. Recently two new species were described from the Eastern Guyana Shield, one from Peru, and one from Brazil. We describe three new species related to the S. rabus species complex with known distribution only in western Amazonia, Colombia. The S. rabus complex consists of the smallest species in the genus; one of the new species is slightly larger than S. rabus and we describe its full osteology; the other two new species are smaller than S. rabus. Wealso described the call and larvae of one of the new species. We provide an updated diagnosis and review the available molecular and phenotypic data for the genus.more » « less
