Abstract: Anoura geoffroyi Gray, 1838, is a phyllostomid bat commonly referred to as Geoffroy's tailless bat. This bat is broadly distributed in the Neotropics from both versants of Mexico into northern and western South America and the Amazon Basin. A. geoffroyi eats mainly pollen, but also consumes fruit, nectar, and insects. It is not of special conservation concern because it is abundant throughout its range. DOI: 10.1644/818.1.

DIAGNOSIS
Anoura geoffroyi (Fig. 1) differs from A. cultrata in having a shortened bladelike p1, the smallest of the mandibular premolars (Nagorsen and Tamsitt 1981; Tamsitt and Nagorsen 1982). A. geoffroyi does not have a complete zygomatic arch, whereas A. cultrata does (Tamsitt and Valdivieso 1966). The skull of A. geoffroyi (Fig. 2) is smaller than that of A. cultrata and is characterized by a braincase that is less tapered anteriorly; a thinner rostrum; a posterior margin of the palate that is less deeply incised; no posterior palatal extension; and pterygoids that are not inflated posteriorly (Handley 1960). A. geoffroyi differs from A. caudifer in having a larger forearm (43-45 mm versus 34- 38 mm), a larger cranium, and a less furred and narrower interfemoral membrane (Tamsitt and Nagorsen 1982; Tamsitt and Valdivieso 1966). A. geoffroyi is most like A. latidens...
