Helicometra pisanoae sp. n. (Digenea, Opecoelidae) is described based on adult specimens from a fish, Trematomus hansoni (Nototheniidae) caught at the Adelie Land (Eastern Antarctic). The newly described species belongs to the group of species with the terminal, infundibuliform oral sucker. The other diagnostic features are: the sucker ratio based on mean diameter 1:0.84-1.02, blind intestinal caeca, the genital pore closely anterior to the intestinal bifurcation, the cirrus sac reaching posteriorly to the level of posterior half of the ventral sucker and the vitelline follicles reaching to the level of the ventral sucker.

A new metacercaria (Digenea, Gymnophallidae) parasite of limpets Nacella (P.) magellanica and N. (P.) deaurata from Isla Conejo Beagle Channel (Tierra del Fuego, Argentina) is described and illustrated. According to the evaluation of characters of the family Gymnophallidae proposed by Ching (1995) the metacercariae can be included in the genus Lacunovermis Ching, 1965. The presence of a ventral pit, a wide genital pore, lateral papillae of oral sucker and broad, multipointed spines within tegumental pits confirm this inclusion. The new metacercariae differ in every measurement and ratios of L. macomae (the only valid species for the genus). The metacercaria show high prevalence (40 to 100%) and overdispersed distribution. This is the first record of the genus Lacunovermis for the Subantarctic waters.
