A NEW FEATHER MITE SPECIES OF THE GENUS TROUESSARTIA CANESTRINI, 1899 (ACARIFORMES: TROUESSARTIIDAE) FROM THE WHITE- CRESTED ELAENIA ELAENIA ALBICEPS (ORBIGNEY ET LAFRESNAYE) (PASSERIFORMES: TYRANNIDAE) IN CHILE

Abstract

A new feather mite species Trouessartia elaeniae sp.n. (Astigmata: Analgoidea: Trouessartiidae) is described from the White-crested Elaenia Elaenia albiceps (Passeriformes: Tyrannidae). This is only the second record of Trouessartia species from hosts of the family Tyrannidae and the third finding of this genus on suboscine passerines. A brief review of taxonomic pa - pers on the genus Trouessartia published in the past thirty years and a summary of the current state of systematics of this genus are provided. The male of recently described T. phylloscopi Burdejnaja et Kivganov, 2011 syn. n. from Phylloscopus trochilus is declared as a junior synonym of T. microcaudata Mironov, 1983 and the female of that species as a junior synonym of T. appen- diculata (Berlese, 1886).
