'''''Nycticeius''''' is a small genus of bats in the vesper bat family, Vespertilionidae, and the only member of the tribe '''Nycticeiini'''. It contains three species, the evening bat (''N. humeralis''), the Cuban evening bat (''N. cubanus'') and ''Nycticeius aenobarbus''. Some authorities include several other Old World species in ''Nycticeius'', but recent genetic work shows that is a completely New World genus. ''Nycticeius'' is of Greek and Latin origin, meaning "belonging to the night".<ref name="Watkins">Watkins, L. C. (1972). Nycticeius humeralis. Mammalian species, (23), 1-4.</ref>
The Cuban evening bat is found only on the island of Cuba, and very little is known about this species. It is similar in appearance to ''N. humeralis'', but is considerably smaller (4–7 grams).
