Saccopteryx

References useful for identifying species of Saccopteryx include Sanborn (1937) and Jones and Hood (1993); both papers provide keys based on external and craniodental morphology. Although three size­graded species (from large to small, S. bilineata , S. leptura , and S. canescens ) are commonly collected sympatrically in Amazonia, the small species at Paracou is S. gymnura , previously unknown from the Guianas.
