Abstract

Recent collections are used to expand existing descriptions of adults of Otophryne robusta and O. steyermarki.The calls of O. pyburni and O. robusta are compared. Tadpoles of O. robusta and O. steyermarki are described. Characters for distinguishing among adults and tadpoles of these two species and O. pyburni are provided. Otophryne is a Guiana shield endemic; O. pyburni is widespread at lower elevations, whereas O. robusta and O. steyermarki occur in southeastern Venezuela and western Guyana, the former at moderate elevations and the latter at higher elevations.
