Saccopteryx bilineata (Temminck, 1838)

Figure 4B

Material examined. PERU • Ojos de Agua private conservation area, Picota Province; 06°49′S, 076°26′W; 500 m elevation; D. Ruelas obs.; 6 individuals observed on the roof of the biological station .

Identification. This species differs from other bats in having two whitish longitudinal wavy stripes on the dorsum. Besides, the individuals had the underparts brownish; the muzzle was simple, pointed, and without a leaf-like excrescence; the uropatagium was thinly

haired to the exertion of the tail; and the tail perforated the upper surface of the uropatagium. These morphological characters agree with those described by Hall (1981), Yancey et al. (1998), and Díaz et al. (2016).

Remarks. This species occurs from Colombia, Trinidad, and the Guianas to Bolivia and Brazil (Hood and Gardner 2008). In Peru, S. bilineata occurs in the Bosque Pluvial del Pacífico, Selva Baja, and Sabana de Palmera ecore- gions ( Pacheco et al. 2009). The new record in the eastern Andes of Peru extends the range of S. bilineata 430 km north from the nearest presious record at San Juan, Pasco department ( Tuttle 1970; Hood and Gardner 2008).
