Raymondiceratinae is a subfamily of Upper Devonian cheiloceratid goniatites in which the sutures have 4 distinct lobes and the growth lines are convex. The subfamily includes three genera.

  • Raymondiceras. named by Schindewolf, 1934 which has a subglubular shell with small closed umbilici and sutures with an incipient lobe in the first lateral saddle. Type genus.
  • Melonites named by Bogoslovskii 1971, which was moved from Cheiloceratidae to Raymondiceratineae by Korn & Klug, 2002.
  • Roinghites named by Korn 2002, which has a thick discoidal shell, with closed umbilici in the adult; fine, convex growth lines and a very shallow, weakly and widely rounded lateral lobe.
