Lonchorhina marinkellei Hernández-Camacho and Cadena-G., 1978 is a bat commonly called Marinkelle's sword-nosed bat. It is one of the largest species of the genus and one of the rarest bats of northern South America, only known from 5 specimens and 1 locality in the eastern llanos of Colombia. Globally, it is considered “Vulnerable” by the International Union for Conservation of Nature and Natural Resources, mostly due to its restricted distribution and the continuing decline in the extent and quality of its habitat.
