Eptesicus innoxius (Chiroptera: Vespertilionidae)

Abstract Eptesicus innoxius (Gervais, 1841) is a vespertilionid bat commonly known as harmless brown bat or harmless serotine. It is a small bat, with woolly, short dorsal fur (5–6 mm), that is brown to pale grayish brown; the sagittal and lambdoidal crests are very low or absent. Eptesicus innoxius occurs in lowlands west of the Andes, with a geographic distribution restricted to northwestern and southern Ecuador, and northwestern Peru, at elevations from sea level to 1,200 m. It is listed as “Near Threatened” (NT) by the International Union for Conservation of Nature because of a suspected population reduction due to a significant decline of habitat where the species occurs.
