with numerous thin high extra ridges on upper and lower molars. Crested cusps and complete pericingulum on upper molars. Metacone smaller than protocone and hypocone smaller than protocone on upper molars, anteroloph and posteroloph as high as the other lophs. Metaconid only slightly protruding in dp4 and p4. Protoconid stronger in molars than in dp4 and p4. Four main cuspids (proto-, meta-, ento- and hypoconid) crested, delimiting an incomplete pericingulid, due to the presence of the sinusid and of the narrow mesoflexid opening. Labial metalophulid I strong and generally short, never connected to a complete transverse lingual metalophulid I. Entolophid rarely complete, often connecting the mesoconid.

). The first has a long anteroflexus and anteroloph ending lingually with a worn stretched anterostyle. This style is weakly attached to the preprotocrista. The protocone is worn following a plane inclined posteromesially from the indistinct endoloph, towards the anterostyle. The hypocone is worn symmetrically, sloping backwards to its junction with the lingual end of the posteroloph. It is only slightly smaller than the protocone. The paracone is slightly stronger than the metacone, but of same height. The labial protoloph bears a swollen worn paraconule, which is aligned labiolingually with it. The paraconule connects the preprotocrista close to the protocone summit with a short lingual protoloph. The labial metaloph, transverse, is short and separates from the metaconule. The latter is strong and obliquely stretched distomesially, towards its attachment with the postprotocrista, close to the protocone summit. The posteroloph ends at the level of the base of the labial metaloph, making the posteroflexus open labially.

) instead the anteroloph is present and well distinct from the protoloph, which joins the preprotocrista closer to the protocone summit than on UM-NAP-58. A short mesoloph fills the labial part of the mesoflexus; it is separated from the mesostyle on UM-NAP-59, and linked to it on UM-NAP-58. On UM-NAP-59, it ends between the extremities of the extra ridges developed labially from the metaconule and distally from the labial part of the protoloph. A paraconule is present on UM-NAP-59 as developed as the metaconule. On both P4s, extra ridges descend from the conules and the protoloph to the mesoflexus. On UM-NAP-59, an anterolophule connects the paraconule to the anteroloph, and a posterolophule connects the metaconule to the posteroloph.

The parastyle is thicker and more elongated or curved labially on M1; the hypocone (and not the protocone as it was incorrectly indicated in the 2021 paper, p. 81) is more reduced and labial on M2, and the posteroloph is shorter ». However, all the M1-2s from Naples and Mas de Gimel have a relatively short posteroloph, ending at the level of the labial part of the metaloph. Among them, the two upper molars from Mas de Gimel have a thicken and curved parastyle (M2: UM-MGL-606; M2: UM-MGL-790) and two of the molars from Naples (M1: UM-NAP-55; and M2: UM-NAP-47), whereas it is not distinct on the M1 UM-NAP-50 and the M1 or M2 UM-NAP-48.

, fig. 5) encompassing the preprotocrista, the protocone, the posprotocrista, the endoloph and the hypocone, all aligned in continuity and with a nearly indistinct lingual sinus. The hypocone, quite smaller than the protocone, connects the posteroloph through a marked angle; this posteroloph is relatively shorter and slightly higher than the anteroloph. A narrow furrow marks the junction of the posteroloph with the distal flank of the metacone. The metacone is quite smaller than the paracone. The mesostyle can be stretched mesiodistally into two elements connected to the postprotocrista and the robust premetacrista, the whole forming the outer part of the pericingulum. Most often, at least one short mesoloph arises lingually from the mesostyle towards the metaconule without fusing with it. The paraconule is most often crescentshaped and directed mesiodistally towards the mesoflexus or/and the anteroflexus. Two to three low short ridges also descend from the protoloph towards the anteroflexus and mesoflexus, as well as from the protocone (protocrista). The ridge underlining the premetacrista-metacone-metaloph arch drops down to join the flank of the metaconule. The latter is crested with short ridges that are clearly visible on little worn teeth, one descending into the posteroflexus and attaching to the posterocingulum, the other, mediolabial, directed towards the mesoloph without joining it.

), the trigonid is shorter labiolingually than the talonid; it is closed with a low premetacristid-anterolophid and the metaconid is only slightly protruding. The protoconid is slightly more distal. Protoconid and metaconid connect with the metalophid I, which limits the anteroflexid distally. From there, a bifurcate mesiodistal ridge descends labially to the mesoflexid. The postprotocristid, whose distal part is indistinct from the mesial ectolophid, joins the ectolophid bearing the mesoconid. Then at the level of the junction between the distal ectolophid and the prehypocristid, the entolophid develops up to the base of the entoconid. There the entoconid appears isolated, separated also from the posterolophid. The hypoconid is followed with a strong posthypocristid, and then a strong distinct hypoconulid precedes the short posterolophid. An additional extra ridge lies in the posteroflexid, parallel to the entolophid.

). The postmetacristid shows a metastylid-mesostylid thickening, and is prolonged in a short lingual mesolophid (UM-NAP-36, NAP-37, NAP-46). A distolabial spur of the protoconid is present on UM-NAP-37, NAP-38, NAP-46 and UM-MGL-617. The postprotocristid,ectolophid, mesoconid, distal ectolophid and prehypocristid are like in m1-2. Numerous ridges converge into the talonid basin. Likewise, numerous ridges converge from the posterolophid to the posteroflexid.The entolophid is either discontinuous or continuous (UM-NAP-36, NAP-38; UM-MGL-617) and the most often connects the entoconid to the mesoconid. On UM-NAP-37, it connects the base of the entoconid and twice the posterior cingulum. The external walls of the unworn UM-NAP-46 are very finely wrinkled.
