We describe Leptolophus sp. (Equoidea) teeth from the late Eocene at Zambrana (Alava, Basque Country). The features of the M2 are comparable to those of Leptolophus sp. from the upper part of the middle Eocene (MP 15-16) of Mazaterón (Soria, Spain). However, there are a number of differences, including the large size and more accentuated hypsodonty. This discovery extends the stratigraphical distribution of Leptolophus Remy, 1965 to the Ludian (Priabonian, MP 18).
