Material examined. PERU • El Quinillal private conservation area, Bellavista Province; 07°04′15″S, 076°23′ 59″W; 316 m elevation; 01.IX.2015; D. Ruelas leg.; mist nets; 1 ♀ ( MUSM 43864 ) and another specimen acciden- tally released GoogleMaps .

Identification. These morphological characters allow us to recognize this species: dorsal fur uniformly reddishbrown with the underparts slightly paler; ears broad, bluntly pointed, and as long as the head; tragus more than one-half the length of the ear and notched at the base; lance-shaped nose leaf with a prominent longitudinal ridge; lance tapers to a sharp point with the entire nose leaf nearly equal in length to the ears; five fleshy protuberances collectively hide the opening to the nostrils; upper lip covered with small, fleshy warts, which hang over the bottom lip; lower lip with an inverted triangular space flanked laterally by elongate, smooth pads; tail longer than the femur, and reaches to the posterior tip of the uropatagium; wings extend to the distal end of the tibia; foot shorter than calcar. Skull elongated with rostrum narrow; nasal arched, curved, and overhang the

nasal opening; palatine with large projection; first pre- molar tiny; second premolar higher than molars; massive molars; broad mesopterygoid fossa; dental formula: 2/2 1/1 2/3 3/3 = 34. External and craniodental measure- ments are shown in Table 2. These morphological characters and measurements are within the variation range for the species following Lassieur and Wilson (1989), Díaz et al. (2016), Morales-Martínez and López-Arévalo (2018), and with specimens of the MUSM collection (Cusco Department: MUSM 19702, 19702; Madre de Dios Department: MUSM 19704).

Remarks. This species occurs from Central America, southern Mexico, The Bahamas, Colombia, Ecuador, Trinidad, eastern and northern Venezuela, eastern Peru, eastern Bolivia, and eastern Brazil (Williams and Genoways 2008). In Peru. L. aurita occurs in the Selva Baja ecoregion ( Pacheco et al. 2009). We report this species for the first time in San Martín department, 410 km north from the nearest previous record at San Juan, Pasco Department ( Tuttle 1970; Williams and Genoways 2008).

Additional records. Moyobamba, Caserio Selva Alegre (MUSM 47731); Rioja, Cueva de Palestina (de los Guácharos) (MUSM 50655).
