IDENTIFICATION: Descriptions and measurements of Lionycteris spurrelli have been provided by Phillips (1971) , Carter and Dolan (1978) , Swanepoel and Genoways (1979) , Williams and Genoways (1980) , Koopman (1993) , Zortéa et al. (1998) , Gregorin and Ditchfield (2005) , Woodman and Timm (2006) , and Woodman (2007) . No subspecies are currently recognized in L. spurrelli ( Griffiths and Gardner, 2008b ) . Our specimens conform in all respects with previous descriptions of this species and exhibit the diagnostic characteristics of L. spurrelli : base of dorsal pelage darker than tips; GLS < 21 mm ; rostrum shorter than braincase; upper premolars not conspicuously elongated; well-developed lingual cusps present on both upper premolars; p4 and p5 short and broad; and main cusps of p4 and p5 high and narrow ( Woodman and Timm, 2006 ; Griffiths and Gardner, 2008b ). Our vouchers fall within the range of measurements reported for L. spurrelli . REMARKS: Two females (MUSM 39196, 39197) that we collected were lactating.
