Abstract

Oxyspirura lumsdeni n. sp. from the orbit of Pedioecetes phasianellus (type host), Tympanuchus pallidicinctus, Centrocercus urophasianus, Bonasa umbellus, and hybrids of P. phasianellus and Tympanuchus cupido in Canada and the United States is distinguished from other members of the subgenus Oxyspirura by the absence of a gubernaculum, the presence and arrangement of three preanal pairs and three postanal pairs of caudal papillae, the presence of deirids, and the length and morphology of the spicules.
