Osteocephalus is a genus of hylinae frogs (tribe Lophiohylini) distributed in the Amazon Basin and the Guiana Shield (Faivovich et al. 2005). There are 24 recognized species of which half have been resurrected or described since 2000 (Frost 2010). Despite these efforts, taxonomic problems persist, including undescribed species and binomials of unknown validity or poorly understood boundaries.
