magnidens species group

The two species of this group, representing the only previously described species of Myrsidea from the Tyrannidae, are characterized as having both sexes with a much larger number of abdominal tergal and/or sternal setae than any other known species from this family. The females have only a modest enlargement of the anterior abdominal tergites (Figs. 1, 3). Although the host identities of both species are uncertain, this group is morphologically distinctive from other Myrsidea species with known host associations with the Tyrannidae .
