Choeroniscus minor (Peters, 1868) is a phyllostomid commonly called the lesser long-tongued bat. It is a medium-size bat with an elongated muzzle, a very long tongue, and other cranial and dental features indicative of its highly specialized adaptations for nectar feeding. Living solitary or in small numbers, it inhabits tropical rain forests from the Amazon Basin of Brazil across northern South America and Trinidad. It has a more extensive geographical distribution than either of its 2 congeners. It is not of special conservation concern but is relatively poorly represented in mammal collections worldwide.
