The term Celastrina iryna does not appear in widely recognized taxonomic databases, scientific literature, or authoritative encyclopedic sources as a valid or established species name within the genus Celastrina (family Lycaenidae). Consequently, there is insufficient encyclopedic information to provide a detailed description of its taxonomy, morphology, distribution, ecology, or conservation status.
The genus name Celastrina is derived from the plant genus Celastrus, reflecting the typical host plants utilized by many species in this group of small butterflies. The specific epithet iryna resembles a personal name of Slavic origin (e.g., Ukrainian “Iryna”), which is sometimes employed in species epithets to honor individuals. If Celastrina iryna were a formally described taxon, the name would likely follow such a convention, indicating that it was named in tribute to a person named Iryna.
Without corroborating references or formal taxonomic registration (e.g., in the International Code of Zoological Nomenclature, the Global Lepidoptera Names Index, or peer‑reviewed publications), the existence and scientific validity of Celastrina iryna cannot be confirmed. Further verification from primary taxonomic sources would be required to determine whether this name represents a synonym, an unpublished manuscript name, or a misinterpretation of another species.
