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.
