Enargia fausta. The species previously treated as E. infumata (of auth.) was renamed because the type of E. infumata is the same species as E. mephisto; see Schmidt (2010a). An enigmatic population of Enargia in the Pacific Northwest may represent a disjunct population of E. fausta, or an introduced, established population of the European E. paleacea.
