Geoffroy St.-Hilaire, 1818) VOUCHER MATERIAL: Tingana : 2 adult males ( FMNH 203340 ; MUSM 39113 ) ; Waqanki : 4 adult females ( FMNH 203338 , 203526 ; MUSM 39111 , 39112 ), 1 adult male ( FMNH 203524 ) ; see table 7 for measurements. IDENTIFICATION: Descriptions and measurements of Anoura caudifer have been provided by Husson (1962) , Handley (1984) , Molinari (1994) , Simmons and Voss (1998) , Mantilla-Meluk and Baker (2006) , Brosset and Charles-Dominique (1990) , and Pacheco et al. (2018) . No subspecies are currently recognized in A. caudifer ( Griffiths and Gardner, 2008a ) . Our Mayo River basin specimens exhibit the diagnostic characteristics of the species: well-developed calcar, slightly smaller than the foot; presence of a short tail; lower lip protruding less than 3 mm beyond upper lip; skull with keel along midline of mesopterygoid fossa that is not flattened posteriorly and usually extends onto septum between basisphenoid pits; and upper last premolar lacking medial internal cusp. Our vouchers fall within the range of measurements reported for A. caudifer . REMARKS: Two females (FMNH 203338, 203526) that we collected were pregnant, each with a single embryo (crown-rump length [CRL] = 20 mm ).
