| abstract | We inspected feather mites (Acariformes: Astigmata) associated with the brown noddy, Anous stolidus stolidus (Linnaeus), for the first time in the Southern hemisphere. Three feather mites are herein reported, including two new species: Alloptes (Sternalloptes) hidasii sp. nov. (Analgoidea: Alloptidae), Analloptes tintinnabulus sp. nov. (Analgoidea: Xolalgidae), and Grenieria bicaudata Dabert & Atyeo, 1997 (Pterolichoidea: Syringobiidae). The latter species was originally described from a different subspecies of this host in Hawaii. |
