Taxonomic Note
The Priocnessus contains multiple North American , many of which are poorly differentiated in published keys. Specimen-based identification often requires examination of male genitalia or detailed wing venation patterns.
Data Deficiency
Despite being described in 1867, P. nuperus remains biologically poorly known. The 27 iNaturalist observations suggest it is encountered infrequently or is underreported, possibly due to identification challenges or genuinely low abundance.
