Abstract
The Tethyan genus “Belemnopsis” of authors, notBayle 1878, includes 110–120 Bajocian to Hauterivian belemnite species and subspecies from Europe and the southern hemisphere. Its type species,Belemnites sulcatusMiller 1826 from the Callovian to Oxfordian of England, belongs to the Boreal belemnite genusLagonibelusGustomesov 1956, since Phillips selected a lectotype for it in 1870. But the subsequent designation of the type species byDouville in 1879 is invalid according to Art. 67 (h) ICZN, and consequentlyBelemnopsisBayle gets a nomen dubium. It is also a homonym ofBelemnopsisEdwards inGray 1849, and has, therefore, to be replaced byPachybelemnopsisRiegraf 1980, a junior subjective synonym, the family Belemnopseidae Naef 1922 by MesohibolitidaeNerodenko 1983, and the suborder BelemnopseinaJeletzky 1965 by PachybelemnopseinaRiegraf inRiegraf et al. 1998.
