Ilyodon lennoni, the Chacambero splitfin, is a species of splitfin endemic to Mexico. This species grows to a length of 7cm (03inches) TL. It has been considered to be a junior synonym of I. whitei, but is currently considered to be a valid species by Fishbase and the California Academy of Sciences. The specific name honours John Lennon (1940-1980), the singer and guitarist with The Beatles.[1]
