Resumo

Species of the feather mite genus Michaelia Trouessart, 1884 are notable for striking bilateral asymmetry in males, displayed in the structure of the anterior legs (both hetero- and homeomorphs) and the opisthosomal lobes (heteromorphs). A new species of this genus, Michaelia neotropica Hernandes and Mironov n. sp., is described from the Neotropical Cormorant Phalacrocorax brasilianus (Pelecaniformes: Phalacrocoracidae) from Brazil. It differs from M. urile (Dubinin, 1953) by having a narrower incision on the inner margins of the opisthosomal lobes anterior to setae h1, and relatively longer legs I with the ambulacrum reaching the midlevel of elongated tarsus II. A key to heteromorphic males of the genus Michaelia is provided. (AU)
