From Konovalova (2015):

Popov (1965) assigned M. aksuensis to a separate genus and indicatedamong the main distinguishing characters the shape of the ventral lobe, the sidesof which converge upward. Popov (1965, 1968), in papers containing descriptionsof this genus and species, figured sutures of three specimens, two of which (specimen nos. 782/84, 2771/324) have aventral lobe with a vertical lyre-shaped sides and were probably drawn fromrepresentatives of the genus DzhaprakocerasPopov, 1965. In the figured suture of the holotype (Popov, 1968, p. 83,text_fig. 16f) the sides of the ventral lobe are almost straight and slightly convergentin the upper part. Based on these figures, Kuzina (1980) assigned M. aksuensis tothe genus Dzhaprakoceras, thereby making Muensteroceratoides a junior synonym. The re-examination of the suture and the studyof the available material show that these specimens have characters indicatedby Popov when he established the genus. The shell shape of M. aksuensis issimilar to that of Muensteroceras, such as M. parallelum (Hall, 1860), M.complanatum (Koninck, 1880), and M.rotella (Koninck, 1880), but the ventral lobe with slightly convex sidesconvergent upwards is not characteristic of Muensteroceras, in which the sidesof the ventral lobe are always straight. The shape of the ventral lobe issimilar to that of Dzhaprakoceras, however in the latter the sides of theventral lobe are parallel. In addition, in Dzhaprakoceras, the umbilicus is usuallyhas a blurred umbilical shoulder, and the shell ontogeny does not show a trend towards the increase in WW/Dm, as inMuensteroceratoides
