Herein we report the first record for Lampronycteris brachyotis in Ecuador, which extends its range about 570 km west of the nearest previously known published record in Loreto, Peru. We captured an adult male on 31 October 2008 in Tarangaro, near the Manderoyacu River, Pastaza province. This locality is placed in a flat, periodically flooded river valley, with small estuaries. The forest is well preserved with high canopy trees. There also are small agricultural patches in the zone.
