IDENTIFICATION: We consulted descriptions and measurements of Sturnira oporaphilum provided by Carter and Dolan (1978) , Anderson (1997) , Velazco and Patterson (2014) , and Molinari et al. (2017) . No subspecies are currently recognized in S. oporaphilum ( Velazco and Patterson, 2014 ; Molinari et al., 2017 ). Our specimen exhibits the diagnostic characteristics of S. oporaphilum : medium size (FA 42–47 mm ); shoulder glands (epaulettes) present but weakly defined; metacarpals III and IV subequal in length, but shorter than metacarpal V; upper inner incisors orthodont; lower incisors bicuspidate; and metaconids and entoconids of m1 and m2 poorly defined, forming a continuous sloping ridge ( Gardner, 2008e ). Measurements of our speci- mens fall within the range of measurements previously reported for the species.
