Rosser William Garrison. 1994. A synopsis of the genus Argia of the United States with keys and descriptions of new species, Argia sabino, A. leonorae, and A. pima (Odonata: Coenagrionidae). Transactions of the American Entomological Society 120(4): 287-368.
A synopsis of all 29 species of Argia occurring north of Mexico includes keys to both sexes based primarily on caudal appendage morphology in males and morphology of the mesostigmal plates in the females, diagnoses, distributional notes and diagnostic illustrations.
Three new species, A. leonorae (Holotype male.-MEXICO: Nuevo Leon state, in FSCA), A. pima (Holotype male. - U.S.A.: Arizona, Pima Co., in USNM), and A. sabino (Holotype male. -U.S.A.: Arizona, Pima Co., in USNM) are described.
The following nomenclatural changes are proposed: Argia mista Navás is considered a junior synonym of A. extranea (Hagen), A. solita Kennedy a junior synonym of A. pallens Calvert, A. spegazzinii Navás a junior synonym of A. plana Calvert, and A. espinalensis Navás a junior synonym of A. translata Hagen in Selys.
