Etymology and nomenclature
The name Actrix was established by Carl Heinrich in 1956. The epithet nyssaecolella combines 'Nyssa' (the plant genus) with '-colella' (a diminutive suffix common in , indicating a small associated with Nyssa). The name 'Actrix' is also an archaic synonym for 'actress' in English, though this is unrelated to the entomological usage.
Taxonomic history
Actrix nyssaecolella was originally described as Tacoma nyssaecolella by Harrison Gray Dyar Jr. in 1904, and later transferred to the Actrix when Heinrich established that genus in 1956. This reclassification reflects ongoing refinement of Phycitinae during the mid-20th century.
