Taxonomic History
The has undergone taxonomic revision; it was formerly classified within but is now recognized as a distinct family based on phylogenetic studies. Some sources, including GBIF and iNaturalist, still list Tineidae as the family due to ongoing database updates.
Subspecies
Two are recognized: Acrolophus laticapitana laticapitana (nominate form) and Acrolophus laticapitana unistriganus Dyar, 1903. The distinction between these forms is based on subtle pattern differences.
