This small bat is recorded on the Pacific side of western Ecuador and northwestern Peru. The current taxonomic name Neoeptesicus innoxius reflects its transfer from Eptesicus.
The dorsal fur is short and woolly, with dark bases and dark brown to grayish-brown tips. Ventral hairs have pale brown bases and buff to white tips. The ears are medium-sized and triangular.
Ecuadorian observations report flight from about 19:00 to 05:00 and roosts under bark about 40 cm above ground or in tree cavities 1–5 m high. It is insectivorous.
