The term Neusticomys derives from the two ancient greek words νευστικός (neustikós), meaning "able to swim", and μῦς (mûs), meaning "mouse, rat".[2][3] N. monticolous and N. vossi primarily inhabit montante regions of west Columbia and eastern Ecuador, with the former noted to occur in the Andean Cordillera and the Occidental mountain range at elevations of 1,800-3,750 meters. The rest inhabit tropical lowland forests primarily in the northern and eastern regions of the Amazon rainforest, whereas N. peruviensis is an endemic species to Peru.[4][5]
This genus contains the following seven species:[4]
- Ferreira's fish-eating rat (Neusticomys ferreirai) — Percequillo, Carmignotto & Silva, 2005
- Montane fish-eating rat (N. monticolus) — Anthony, 1921
- Musso's fish-eating rat (N. mussoi) — Ochoa G. & Soriano, 1991
- Oyapock's fish-eating rat (N. oyapocki) — (Dubost & Petter, 1978)
- Peruvian fish-eating rat (N. peruviensis) — (Musser & Gardner, 1974)
- Venezuelan fish-eating rat (N. venezuelae) — (Anthony, 1929)
- Voss' fish-eating rat (N. vossi) — (Hanson, D’Elía, Ayers, Cox, Burneo & Lee, 2015)
