Comments. This Ponto-Mediterranean species was identified in Azerbaijan ( Horváth 1889), subsequently it was recorded only in Armenia and Iran ( Rider 2006; Péricart 2010). It is recorded as new to Turkey in the present study. All Turkish specimens were collected on Thlaspi kurdicum Hedge (Brassicaceae) which is probably its host plant (new host plant record).
