Taxonomy and systematics

Ethmia pusiella is the type species of the proposed genera Anesychia and Melanoleuca, which are now considered junior synonyms of Ethmia. If considered separate from Ethmia, the senior synonym Anesychia must be used.[1]

Two subspecies are accepted nowadays:[1]

• Ethmia pusiella pusiella – western populations, east to Ural Mountains and Asia Minor
• Ethmia pusiella deletella – eastern populations, Central Asia and Tien Shan

In earlier times, E. candidella and E. fumidella were considered varieties of E. pusiella.[1]

Junior synonyms of E. pusiella are:[1]

• Ethmia deletella de Lattin, 1963
• Ethmia lithospermella (Hübner, 1789)
• Ethmia scalacella (Kühn, 1777)
• Phalaena (Tinea) pusiella Linnaeus, 1758
• Tinea lithospermella Hübner, 1789
• Tinea scalacella Kühn, 1777
