Excerpt from Journal of Hymenoptera Research, Vol. 14: April, 2005 Thus, evidence support M. Basalis as one of the oldest existing stephanids. Howev er, while it lacks most Of the derived fea tures of Megischus, it does have a few of them, which is enough to indicate a next evolutionary step in relation to Schletter erius and Stephanus. Therefore, it is reason able to assume that M. Basalis is, in fact, an intermediate form between Stephanus and Megischus, representing an entirely new step to be considered in phylogenetic interpretations Of the family. Its current placement in Megischus is based on the fact that if Stephanus is expanded to in clude some of the derived features of Meg ischus those present in M. Basalis), then these genera would become close enough to be synonymized, a clearly un stable taxonomic decision at this point.
