Differs from A. defungens in its yellow-green articles, phyllichnia that are occasionally strongly rounded-convex, and teeth that are straighter-sided and often somewhat spreading. broader teeth that often overlap and are mostly erect and appressed (occasionally teeth spreading) and in typically having articles more waxy and of the same diameter over their whole length.
