VOUCHER MATERIAL: El Diamante: 2 adult females ( FMNH 203474 View Materials ; MUSM 39258 ), 2 juvenile females ( FMNH 203478 View Materials ; MUSM 39262 ), 6 adult males ( FMNH 203472 View Materials , 203480 View Materials , 203658 View Materials ; MUSM 39259 , 39260 , 39261 ), 1 juvenile male ( FMNH 203476 View Materials ) ; Tingana: 10 adult females ( FMNH 203484 View Materials , 203488 View Materials , 203662 View Materials , 203664 View Materials ; MUSM 39256 , 39264 , 39271 , 39272 , 39274 , 39276 ), 1 juvenile female ( FMNH 203482 View Materials ), 13 adult males ( FMNH 203486 View Materials , 203490 View Materials , 203492 View Materials , 203494 View Materials , 203668 View Materials ; MUSM 39263 , 39266–39270 , 39273 , 39277 ), 7 juvenile males ( FMNH 203496 View Materials , 203660 View Materials , 203666 View Materials , 203670 View Materials ,

IDENTIFICATION: We consulted descriptions and measurements of Hylaeamys perenensis provided by Patton et al. (2000, as Oryzomys perenensis ), Weksler et al. (2006), Weksler and Percequillo (2011), Hice and Velazco (2012), Percequillo (2015b), and Brito and Pardiñas (2017a). No subspecies are currently recognized in H. perenensis ( Percequillo, 2015b; Brito and Pardiñas, 2017a). H. perenensis is distinguished from other species in the genus by the following combination of characteristics: medium size (head and body length 81–169 mm; tail 94–154 mm); tail shorter than head and body length; hind feet with medium-sized hypothenar pads; skull large and robust; incisive foramina long, narrow, teardrop shaped (length 3.6–6.0 mm; width 1.5–2.9 mm); roof of mesopterygoid fossa completely ossified; and M2 without a mesofossette and with long paraflexus ( Percequillo, 2015b; Brito and Pardiñas, 2017a). Our specimens conform to previous descriptions of the species, and their measurements fall within the range of size variation previously documented.
REMARKS: In the Mayo River basin, Hylaeamys perenensis was commonly captured in cultivated areas and flooded forests; it was less commonly captured in a coffee plantation and near a small stream. One pregnant female was recorded at the Tingana location. Lareschi and Velazco (2013) reported the mite Gigantolaelaps oudemansi type I from our specimens.
