Hylaeamys yunganus (Thomas, 1902)

VOUCHER MATERIAL: El Diamante: 2 adult males ( MUSM 39278 , 39279 ), 1 juvenile male ( FMNH 203498 ) ; Tingana: 1 adult male ( FMNH 203500 ) ; see table 22 for measurements.

IDENTIFICATION: We consulted descriptions and measurements of Hylaeamys yunganus provided by Anderson (1997, as Oryzomys yunganus ), Musser et al. (1998, as Oryzomys yunganus ), Patton et al. (2000, as Oryzomys yunganus ), Voss et al. (2001, as Oryzomys yunganus ), Weksler et al. (2006), Weksler and Percequillo (2011), Hice and Velazco (2012), Percequillo (2015b), and Brito and Pardiñas (2017b). No subspecies are currently recognized in Hylaeamys yunganus ( Percequillo, 2015b; Brito and Pardiñas, 2017b). Our Mayo River basin specimens exhibit the diagnostic characteristics of the species: tail shorter than head and body length; dorsal fur dense and velvety; claws sparsely covered by ungual tufts; hind feet lacking hypothenar pads; posterior margins of dentary shallowly concave between condyloid and angular processes; M2 with a distinct mesofossette and short paraflexus; and m2 with a conspicuous entoflexid ( Percequillo, 2015b; Brito and Pardiñas, 2017b). Measurements of our speci- mens fall within the range of measurements reported for the species.

REMARKS: All our specimens were captured in cultivated areas. Lareschi and Velazco (2013) reported the mites Androlaelaps fahrenholzi and Gigantolaelaps oudemansi type I from our specimens.
