Nadejdolepis bealli n. sp. a parasite from Calidris alpina in Alaska (USA), is described and illustrated. It is 3-4 cm long and has: rostral nitiduloid hooks 95-96 microm long, with the blade a little longer than the handle; three testes in a symmetrical triangle; a cirrus-sac 175 microm long, not crossing the median line; a cirrus borne on an unarmed basal bulb, 25 microm long when evaginated, and armed with numerous, compact and very thin spines 1 microm long; a short (25 microm) membranous and tubular vagina with neither a sclerotinoid section nor a sphincter; and a pyriform seminal receptacle. The species is differentiated from the other species of the genus with rostral hooks of comparable length by the configuration of the male and female genital ducts; they have no equivalent particularly in the shortness of the evaginated cirrus and the type of spines with which it is armed. Mention is also made of the presence of Nadejdolepis paranitidulans (Golikova, 1959) and Wardium amphitricha (Rudolphi, 1819) from the same host in Alaska.
