Resumen:
The taxonomy of the South American genus Exomegas Gill 1883 has beenunstable owing to the unknown status of the type specimen of its type species, Petromyzon macrostomus Burmeister 1868. Here we announce the finding of the holotype in the MACN ichthyology collection. Whereas Exomegas type species is recognized based on its holotype, Exomegas gallegensis (Smitt 1901) new status isproposed. These preliminary results resolve a century-long taxonomic uncertainty and foster a nomenclatural arrangement for a Southern Hemisphere lamprey genus.
