Archibald, Bruce, Cannings, Robert A., Erickson, Robert J., Bybee, Seth M. & Mathewes, Rolf W., 2021, The Cephalozygoptera, a new, extinct suborder of Odonata with new taxa from the early Eocene Okanagan Highlands, western North America, Zootaxa 4934 (1), pp. 1-133 : 102

Dysagrionites Archibald & Cannings , new collective genus

Fig. 62–64 .

Definition. This genus-level collective group name is proposed for any fossil species referable to the Dysagrioninae that can be clearly defined at the species level, separating them from other species of the subfamily, but whose orthotaxon generic affinity is unclear by the preservation of its currently known specimens.

Etymology. The collective genus name is formed from Dysagrion , the name of type genus of the subfamily Dysagrioninae , and the suffix – ites, often used in the names of fossil genera, including parataxa. Gender masculine.

Discussion. As a collective group, a definition is provided, but not a diagnosis or description, and a type species is not designated (International Trust for Zoological Nomenclature 1999: article 42.3.1). Species are distinguished from all other species of the bounding group, the Dysagrioninae .
