Saccopteryx canescens Thomas, 1901

VOUCHER MATERIAL (TOTAL = 4): Isla Padre (MUSM 4206, 4354, 4357, 4358); see table 8 for measurements.

UNVOUCHERED OBSERVATIONS: During the CEBIO bat course at Jenaro Herrera, Saccopteryx canescens was recorded using acoustic methods.

IDENTIFICATION: Saccopteryx canescens can easily be distinguished from other congeneric species by the following combination of features: dorsal pelage grayish or brownish, clearly bicolored, and lightly frosted with gray; paired whitish dorsal stripes indistinct, but visible; forearm <41 mm; length of maxillary toothrow ≤ 5 mm; greatest width across molars (M3–M3) <6 mm (Hood and Gardner, 2008; López- Baucells et al., 2018). Descriptions and measurements of S. canescens were provided by Sanborn (1937), Husson (1962, 1978), Brosset and Charles-Dominique (1990), Jones and Hood (1993), and Hood and Gardner (2008). No subspecies are currently recognized (Simmons, 2005; Hood and Gardner, 2008).

Our material from the Yavarí-Ucayali interfluve consists of fluid specimens that could be identified unambiguously as Saccopteryx canescens based on external characters.
