Specimens were preserved in AG (alcohol 75%, glyserin 5%), cleared in lactophenol solution and mounted by Hoyers medium. Mite of the genus Leptus (Acari: Erythraeidae) wasremoved from larva and adult of Cassida persica Spaeth (Coleoptera: Chrysomelidae). The first time in the world C. persica was observed as a new host of Leptus n. sp.
