This record represents an extension of its distribution range, ca. 400 km east of the nearest known locality of occurrence ( see Lynch, 1997 ). As S. sulcatus is the only species of the genus widely distributed in lowland Amazonia, this record also expands the known distribution for the genus Strabomantis ( Hedges et al., 2008 ) . Based on the fact that Strabomantis species are rarely reported for Brazilian Amazonia, are quite similar considering external morphology, and we still have little knowledge on the genetic variation within S. sulcatus , other species could likely be masqueraded under this name across lowland Amazonia.
