Abstract
Four new species of the genus Nacaeus (Staphylinidae: Osoriinae) are described from Central and South America: N. collinatus, N. colombinellus, N. honduranus and N. fl avoelytratus. Another species, N. americanus, is redescribed and transferred from the genus Lispinodes to Nacaeus. A rough overview to three species groups is given and the newly described species are compared in detail with similar species. N. nevermanni (Bernhauer, 1942) is synonymised to N. spegazzini (Bernhauer, 1933) and new records of the species are published.
