It was reranked as Hypophylloceras (Neophylloceras) by Birkelund (1965), Morozumi (1985), Wright et al. (1996) and Ifrim et al. (2013); it was reranked as Phylloceras (Neophylloceras) by Henderson and McNamara (1985), Ward and Kennedy (1993), Kennedy (1999) and Arkadiev et al. (2000).
It was assigned to Phylloceratidae by Matsumoto (1959) and Matsumoto (1984); to Phylloceras by Henderson and McNamara (1985), Ward and Kennedy (1993), Kennedy (1999) and Arkadiev et al. (2000); to Phylloceratitida by Sepkoski (2002); to Hypophylloceras by Birkelund (1965), Morozumi (1985), Wright et al. (1996) and Ifrim et al. (2013); and to Phylloceratinae by Henderson (1970), Courville and Odin (2001), Murphy and Rodda (2006) and Shigeta et al. (2015).
