1Dolerini is a tribe of in the Selandriinae, comprising two : Dolerus Panzer and Prionourgus Goulet. Dolerus, the genus, contains 72 Nearctic organized into seven subgenera and one species group, while Prionourgus is . Members are distinguished by structural characters used in cladistic analyses to reconstruct species relationships. The tribe has undergone extensive taxonomic revision, with numerous new species and subgenera described from across the Nearctic region.

Identification
Dolerini can be distinguished from other Selandriinae tribes by structural characters analyzed in cladistic studies. Within the tribe, Dolerus and Prionourgus are separated by diagnostic combinations of morphological features. Dolerus are further subdivided into subgenera (Neodolerus, Achaetoprion, Oncodolerus, Loderus, Dicrodolerus, Dolerus s. str., and Dosytheus) and the nitens species group based on structural character states. Specific identification requires examination of detailed morphological features illustrated in taxonomic revisions.

Taxonomic history
The tribe has been extensively revised, with the 1986 monograph recognizing two , seven subgenera within Dolerus, and describing 23 new , four new subgenera, one new genus (Prionourgus), two new , and one replacement name (Dolerus sayi for D. collaris Say, a junior secondary homonym).
Phylogenetic research
Relationships between Dolerini have been reconstructed using cladistic based on structural characters, with the resulting used to propose a formal classification for higher within the tribe.
