Price, Roger D., Hellenthal, Ronald A. & Dalgleish, Robert C., 2005, The genus Myrsidea Waterston (Phthiraptera: Menoponidae) from tyrant­flycatchers (Passeriformes: Tyrannidae), with descriptions of 13 new species, Zootaxa 1048, pp. 1-20 : 3

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 .
