Abstract
A new monobasic genus of parasitic mites, Phalarophilus fulicarius gen. nov., sp. nov. (Acariformes, Syringophilidae) is described from feather quills of Phalaropus fulicarius (Linnaeus) (Charadriiformes, Scolopacidae) from USA. Females of the new genus differs from those of the genus Bochkovia Skoracki et OConnor, by having the rounded posteriorly stylophore, edentate movable cheliceral digits, propodonotal setae arranged 2-1-1-2, thin and smooth dorsal setae of the idiosoma, smooth dorsal setae of legs I and II, and by the presence of setae vsI; males are distinguished by the presence of the propodonotal setae arranged 2-1-1-1-1. Additionally, two new syringophilid species recorded from aquatic birds in North America and three new host associations of these mites are recovered.
