IDENTIFICATION: The review of the Anoura geoffroyi species complex by Mantilla-Meluk and Baker (2010) elevated the two nonnominal subspecies of A. geoffroyi to species rank: A. peruana ( Tschudi, 1844 ) and A. lasiopyga (Peters, 1868) . Based on the distributions provided by Mantilla-Meluk and Baker (2010) , two Anoura species occur in Peru : A. peruana from the middle to high elevations of the Andes from Bolivia to Colombia , and A. geoffroyi from middle and low elevations of the eastern versant of the Andes from Brazil to northern South America, including the island of Trinidad . However, Pacheco et al. (2018) suggested that Mantilla- Meluk and Baker (2010) erroneously removed A. geoffroyi from the list of species present in Peru . Our Mayo River basin voucher material conforms with previous descriptions of A. geoffroyi , sharing the diagnostic characteristics of the species with specimens from Brazil (e.g., AMNH 78288, 78296; see below) and hence confirming presence of this species in Peru . Descriptions and measurements of Anoura geoffroyi have been reported by Griffiths and Gardner (2008a) and Mantilla-Meluk and Baker (2010) . No subspecies are currently recognized in A. geoffroyi sensu stricto ( Mantilla-Meluk and Baker, 2010 ). The Mayo River basin specimens exhibit the diagnostic characteristics of the species: narrow uropatagium with a fringe of hair; lack of tail; zygomatic arches present; medial internal cusp of P5 prominently protruding from narrow base of tooth; upper and lower last two premolars narrow; and first lower premolar approximately the same size and shape as other lower premolars ( Griffiths and Gardner, 2008a ; Mantilla-Meluk and Baker, 2010 ).
