Suborder Ussuritina nov.

Diagnosis.—Semiinvolute to evolute derivates of Meekoceratina with more or less simple monophyllic suture. The type of early lobe ontogeny like in Meekoceratina and Otoceratina: VL: ID – (V 1 V 1) LU 1: ID – (V 1 V 1) LU 1 U 2: I(D 1 D 1).

Remarks.—Differs from the Meekoceratina Druschits and Doguzhaeva in Druschits et al. 1976 and Phylloceratina Arkell, 1950 by monophyllic suture and more advanced or more primitive septal necks, respectively (amphichoanitic type for Monophyllites was fixed at the end of the second whorl; see Zakharov 1978). From Phylloceratina new suborder seems to be distinguished additionally by simpler (four−lobes) primasuture. Possibly two superfamilies: (i) Ussuritoidea Hyatt, 1900 (families: Flemingitidae Hyatt, 1900 , Palaeophyllitidae Popov, 1958 (in Kiparisova and Popov 1958), Ussuritidae Hyatt, 1900 ), and (ii)?Danubitoidea Spath, 1951 (at least family Danubitidae Spath, 1951 ). Lower (Olenekian)–Upper (Carnian) Triassic.
