Diphylla ecaudata Spix, 1823

VOUCHER MATERIAL: El Diamante: 1 adult female ( MUSM 39188 ), 2 adult males ( FMNH 203522 ; MUSM 39189 ) ; see table 6 for measurements.

IDENTIFICATION: Descriptions and measurements of Diphylla ecaudata have been provided by Swanepoel and Genoways (1979), Greenhall et al. (1984), and Kwon and Gardner (2008). Currently two subspecies are recognized: D. e. centralis (southern United States southward through eastern Mexico and Central America) and D. e. ecaudata ( Venezuela, Colombia, Ecuador, Peru, Bolivia, and Brazil, excluding the central Amazon basin) ( Greenhall et al., 1984; Kwon and Gardner, 2008). Our Mayo River basin specimens exhibit the diagnostic characteristics of the species: thumb small (usually less than 13 mm), lacking basal pads; uropatagium well furred; occlusal margin of lower inner incisors with four lobes, of lower outer incisors with three lobes; two upper incisors and two lower molars on each side ( Kwon and Gardner, 2008; Cirranello et al., 2016). Our Mayo River basin voucher material represents the nominate subspecies.

REMARKS: Our female (MUSM 39188) was lactating.
