Euphydryas anicia magdalena is a of checkerspot to the Magdalena Mountains of west-central New Mexico. It was originally described by W. Barnes and J.H. McDunnough in 1918. The subspecies is considered rare and elusive, inhabiting alpine environments at high elevations. It has been featured in conservation literature, most notably in Robert Michael Pyle's novel "Magdalena Mountain," which helped raise awareness of this distinctive black alpine butterfly. The subspecies is currently synonymized under Occidryas anicia in some taxonomic databases, reflecting ongoing revisions in checkerspot butterfly .

Identification

The all-black or nearly black coloration distinguishes Euphydryas anicia magdalena from other Euphydryas , which typically exhibit contrasting orange, red, or yellow markings on a dark background. This subspecies can be separated from other dark alpine butterflies by its specific geographic restriction to the Magdalena Mountains and its association with the Euphydryas anicia group. Close examination of genitalic or molecular analysis may be required to distinguish it from other dark-colored Melitaeini in sympatric alpine .
