Anarsioses
Anarsioses is a genus of leafmining moths in the family Gracillariidae, established by Davis in 2019 to accommodate the species formerly known as Phyllonorycter aberrans. The genus was separated from Phyllonorycter based on distinctive morphological and molecular evidence, particularly the unusual asymmetry of the male genitalia and differences in larval biology. It is currently monotypic, containing only the type species Anarsioses aberrans.
