A new feather mite species of the genus Trouessartia canestrini (Acariformes: Trouessartiidae) from the Northern rough-winged swallow Stelgidopteryx serripennis (Passeriformes: Hirundinidae) in Pennsylvania

Abstract

A new feather mite species, Trouessartia stelgidopteryx sp. n. (Astigmata: Trouessartiidae), is described from the Northern rough-winged swallow Stelgidopteryx serripennis Newton (Passeriformes: Hirundinidae) in Pennsylvania, USA. \n \n The new species is close to the minutipes species group and differs from its representatives and all other known species of the genus Trouessartia in having a unique combination of features in males: the opisthosomal lobes are much longer than wide, they are separated by a large semi-ovate terminal cleft, and their lobar apices bear semi-ovate terminal lamellae with a smooth margin. \n\n DOI: 10.21684/0132-8077-2016-24-2-3-9
