CORYPHELLA SANAMYANAE (KORSHUNOVA ET AL., 2017 ) COMB. NOV.

( FIGS 14 , 15E–G , 16C, D )

Diagnosis: Body wide, with continuous notal ridge. Rhinophores smooth, rarely slightly wrinkled, white with white opaque pigment covering two-thirds of their length. Cerata in continuous rows, long, colour from reddish-orange to bright red. Jaws triangle plates, masticatory process with three to six rows of strong conical denticles. Radula triserial. Rachidian tooth triangle plate of different proportions with noncompressed or slightly compressed conical cusp and six to eight denticles on each side. Lateral teeth triangle, bearing 8–11 small denticles, with attenuated basal process. Vas deferens slightly curved, widened. Penis lobe-shaped.
