Diez, Patricia A., Fidalgo, Patricio & Roig-Alsina, Arturo, 2013, Revision of the ocellatus species-group of the genus Plumarius Philippi 1873 (Hymenoptera, Chrysidoidea, Plumariidae), with description of three new species from Argentina, Zootaxa 3721 (1), pp. 85-91 : 86

Plumarius ocellatus species-group

The species-group treated in this contribution comprises three new species described below. The group can be identified by the large ocelli, the lateral ones reaching or surpassing the upper margin of the head, by the supratorular line crossing the median ocellus, and by the transverse head, 1.3 or more times as wide as high. These features exclude from the group all other species of Plumarius known to us.
