Synonyms

Microlissoceras was named by Sturani (1971). Its type is Lissoceras (Microlissoceras) pusillum.

It was reranked as Lissoceras (Microlissoceras) by Besnosov and Mitta (1993) and Zaton and Marynowski (2006); it was synonymized subjectively with Lissoceras by Zatoń (2010).

It was assigned to Lissoceras by Besnosov and Mitta (1993) and Zaton and Marynowski (2006).
