Material.— Alcoi Cristian, MN14 : 1 m 3 ( AC 0-88), 1 M1, M2 ( AC 0-87). Alcoi 2, MN14 : 1 m 1, m2 (AL2C-97), 1 m 3 (AL2C-47); 1 m 1, m2 (AL2D-290), 1 m 3 (AL2D-356), 3 M1, M2 (AL2D-291-293). La Bullana, MN14 : 4 m 1, m2 (LB2B-6, LB2B-176, LB2B-242, LB2B-243), 1 m 3 (LB2B-179), 1 P4 (LB2B-178), 2 M1, M2 (LB2B-241, LB2B-253), 1 M3 (LB2B-177) .

Measurements.—See Table 2.

Description.— m1, m2: The occlusal outline of these teeth is trapezoidal or subrectangular. The anterolophid is connected to the protoconid in three specimens, and unconnected in a further three. There is no anterotropid. The metalophid is connected to the metaconid. The centrolophid is long, reaching the metalophid in 3 out of 6 specimens. The metaconid and entoconid are separated. The posterotropid is well developed. The hypoconid is large.

m3: The occlusal outline of this tooth is sub-trapezoidal. The anterolophid and the protoconid are separated. There is no anterotropid. The metalophid is connected to the metaconid. There is a short centrolophid, not connected to the metalophid ( Fig. 2S View Fig ). The metaconid and entoconid are separated. There is no posterotropid.

P4: The occlusal outline of this tooth is subtriangular. There is no anteroloph, and the protoloph is discontinuous. The paracone and metacone are higher than the protocone. There is a well-developed precentroloph and a short postcentroloph. The endoloph is continuous.

M1, M2: The outline of these teeth are subrectangular or trapezoidal. The anteroloph and paracone are connected basally in AC0-87, but not connected in any of the other specimens. In some specimens (especially AC0-97), the protoloph and metaloph are distinctly sinuous. Both centrolophs are usually present. The posteroloph is connected to the endoloph. There are three roots.

M3: The occlusal outline of this molar is trapezoidal. The anteroloph is separated from both protoloph and paracone. There is neither an anterotrope nor a posterotrope. The paracone and metacone are high and separated. The protoloph and metaloph are continuous. Both centrolophs are present and well developed, with the postcentroloph being longer and interrupted ( Fig. 2P View Fig ). The endoloph and posteroloph are connected and continuous.

Remarks.— Eliomys intermedius from the Early Pliocene (early Ruscinian–early Zanclean; Mansino et al. 2013) localities of AL2-C and AL2-D is slightly bigger than specimens from the slightly older localities of AC-0 and LB-2B ( Table 2), but all of the specimens from these sites fall within the range of E. intermedius from Sète, the type locality of the species

Adrover 1986). The specimens of E. intermedius from AC-0, AL2-C, AL2-D, and LB-2B have higher and thicker lingual walls than E. truci and E. yevesi , sinuous crests, a rounded occlusal outline, and two well-developed centrolophs in the upper molars (M1, M2 from AC-0 and AL2-D, and M3 from LB-2B). These features agree with E. intermedius .

Stratigraphic and geographic range.— MN 14, Early Pliocene–early Pleistocene (MQ2) of the Alcoy and Cabriel, and Calatayud-Teruel basins of Spain and the Aquitaine, Paris, and Sud-est basins of France. Other reported occurrences

Bruijn et al. 1970) are dubious.
