A new feather mite of the genus Promegninia gaud et atyeo, 1967 Aacariformes: Avenzoariidae) from the Gray-headed Albatross Thalassarche chrysostoma (Procellariiformes: Diomedeidae)

Abstract

A new feather mite species Promegninia thalassarche sp. n. (Avenzoariidae: Bonnetellinae) is described from the Gray-headed Albatross Thalassarche chrysostoma (Forster) (Procellariiformes: Diomedeidae) from South Georgia Island. The new species is morphologically close to the type species of the genus, P. pedimana (Trouessart, 1899), and most clearly differsfrom that species by having the terminal lamellae bidentate in males and the hysteronotal and humeral shields fused in females.
