The generic and higher level classification of phyllostomids used herein follows Peffley et al. (MS). Notable changes from current usage (Koopman, 1993) include our use of Glossophaginae to include lonchophyllines, our recognition of Glyphonycteris and Trinycteris (formerly included in Micronycteris) as full genera, and our use of Ectophylla to include Mesophylla. Emended diagnoses of Glyphonycteris, Micronycteris, Trinycteris, and Ectophylla are provided to justify these new usages.

In the course of our fieldwork at Paracou we captured 49 phyllostomid species belonging to the subfamilies Desmodontinae (2 species), Glossophaginae (5 species), Phyllostominae (25 species), Carolliinae (2 species), and Stenodermatinae (15 species). An additional 15 species (3 glossophagines, 4 phyllostomines, 1 carolliine, and 7 stenodermatines) are known from other collecting localities in French Guiana and Surinam (appendix 1), and some of these could also be expected to occur in our study area. One of the phyllostomid species reported below is described as a new species, and two others were previously unknown from French Guiana.
