Seven species are currently recognized, including the large-bodied (greatest length of skull >24.5 mm) robusta, handleyi, hesperia, and bokermanni and the small-bodied (greatest length of skull <24.5 mm) thomasi, dekeyseri, and mordax. Lonchophylla species range throughout the Neotropics and include endemics in Amazonia, the Cerrado, and the arid regions of coastal Peru and Ecuador. In this paper I describe a new large-bodied species, Lonchophylla chocoana, from the subtropical rainforests of the Choc贸 in southwestern Colombia and northwestern Ecuador. I also document the diagnostic external, craniodental, and mitochondrial characters of the new species and summarize morphological characteristics for the new species and its sympatric congeners
