There are only two known valid allopatric species of Valenciidae, a monogeneric Mediterranean family of cyprinodontiform fishes recently erected by Parenti: Valencia letourneuxi and V. hispanica. The first, now found also in R. Pinios and R. Alfios in Peloponnese, is endemic in western-Greece district. The second is spread only in the Iberian Peninsula, but its detailed distribution is unclear.
