COMMENTS

The specimen MNHN.F.B13464 shows very elongate and straight rostrum with only dorsal spines. Therefore, it is different from H.rogerfrattigianii Schweigert, 2011 , and H. norbertwinkleri Schweigert, 2011 , having two and three ventral spines respectively on the rostrum. It is different from H.prohoscideawulfi Schweigert & Garassino, 2004 , that has a remarkably long, ventrally curved rostrum. Moreover, the studied specimen shows nine dorsal spines on the rostrum as observed in H. frischmanni Oppel, 1862 and H.serrata Münster, 1839 . As pointed out by Van Straelen (1925: 103), H. frischmanni has the same number of rostral spines than H. serrata . We here follow the opinion of the first reviewer considering Oppel’s species as synonym of the type species and we assign our specimens to H. serrata .
