Abstract
A new ammonite genus of the himalayitids is described for the group of Hopl ites bergeroni Kilian, 1889. Kilianites gen. nov. is only known by its macr oconchs (h I), until now ascribed to Protacanthodiscus, macroconch of Duran gites (pars), or/and Neocosmoceras. The relationships with Protacanthodiscu s and Neocosmoceras are discussed, taking into account characters of the on togenesis and stratigraphic position: Kilianites gen. nov., of the Berriasi an Euxinus Zone, Jacobi Subzone (= calpionellids B zone) succeeds the Duran gites-Protacanthodiscus acme in the Upper Tithonian Durangites Zone (= A2 a nd A3 calpionellids subzones).
