In 1914,
Gambusia yucatana was introduced to science by
Charles Tate Regan, in a work entitled "Descriptions of two new cyprinodont fishes from Mexico, presented to the British Museum by Herr A. Rachow." That original description can be viewed online, on page 67, at the
Biodiversity Heritage Library There it's seen that four
type specimens were taken at
Progreso, Yucatán.
Etymology The genus name
Gambusia derives from the Cuban term,
Gambusino, which means "nothing", usually in the context of a joke or a farce -- as when one catches
gambusinos, not really catching much of anything. The species name
yucatana honors the Yucatán Peninsula where it mainly occurs. == Similar species ==
