The dragonfly family Corduliidae presents significant challenges to taxonomists due to the conservative external morphology shared across many genera, particularly within the complex often referred to as the "Somatochlora group." The taxon Piercedaspis idalis was originally described by Walker (1942) based on a small series of specimens collected in the Gaspé Peninsula, Quebec. Walker initially placed the species within Somatochlora but noted the "bizarre and distinct" morphology of the male cerci, which possess a distinct, needle-like process not seen in other Nearctic congeners.
