Diagnoza

The species has been suggested by Groessens (1914) ro be a homeomorph of unrelated older Dollymae hassi Yoges,1959 for which the generic name Icriognathodus Gedk, 1984 is available (Gedik 1984). Its distribution elsewhere suggests that it may be reworked from strata deposited immediately below the invasion of the S.anchoralis fauna.
