Hylaeamys Weksler et al., 2006

Members of the genus Hylaeamys —formerly classified in Oryzomys (see Weksler et al., 2006)—are among the most commonly trapped cricetids in cis-Andean lowland rainforests ( Percequillo, 2015b). Two species, H. perenensis and H. yunganus , are sympatric throughout western Amazonia, including the Yavarí-Ucayali interfluve. Unfortunately, these species are not consistently distinguishable in the field because only dental features are diagnostic. Therefore, unvouchered records are unreliable, and even specimens with heavily worn teeth cannot be confidently identified without DNA sequence data.

Capture data summarized below is consistent with previously reported trapping results from other Amazonian research sites ( Malcolm, 1991; Patton et al., 2000; Voss et al., 2001; Hice and Velazco, 2012) in suggesting that species of Hylaeamys are exclusively terrestrial.
