Abstract
Anophryocephalus inuitorum sp.nov. and A. arcticensis sp.nov. are desc ribed from ringed seals (Phoca hispida hispida) in the eastern Canadia n Arctic: the latter species is also reported from harp seals (Phoca g roenlandica) in the Gulf of St. Lawrence. Anophryocephalus inuitorum i s most similar to A. skrjabini, but can be distinguished by fewer test es (14-27) and smaller dimensions of the strobila, neck (3.0-5.9 mm lo ng), and cirrus sac (31-70 mu m long), diameter of the genital atrium (44-68 mu m), and length of the male canal (23-42 mu m long). Anophryo cephalus arcticensis resembles A. nunivakensis in the structure of the scolex, but is readily distinguished by a longer neck (8.9-14.7 mm), an elongate cirrus sac (60-98 x 44-73 mu m) with a substantially thick er muscular wall, a more globular vitelline gland, and larger embryoph ores (29-41 mu m long) and oncospheres (24-34 mu m long). These are th e first species of Anophryocephalus to be described from phocines in t he eastern Canadian Arctic, and are included in a revised key for the genus.
