Longinos Navás described approximately 180 species of Mantispidae. Name-bearing types for almost 20% of these species (n = 36) were found in the Muséum national d'Histoire naturelle in Paris (MNHN). Here we provide data on the type specimen(s) and the history of major name changes for each of the Navás species held in the MNHN collection. In addition to three holotypes and five lectotypes previously identified in the collection, lectotypes are designated for 24 species, and syntypes are identified for another three species. Also, we provide a list of the paralectotypes and non-type specimens that Navás identified and that are housed in the collection. Finally, we identify two Navás species whose type specimens are apparently missing from the collection, and another whose type had been reported as possibly in the collection but was not found.
