Protoheterophyes spuriocirrus gen. et sp. nov. (Trematoda, Heterophyidae) from terns and a gull collected in tropical Queensland differs from other heterophyines in having a dextral genital pore and an eversible genital sinus that opens simply into the genital sac. The confused and confusing term gonotyl is examined and dissected into three distinct and non-homologous anatomies. It is proposed that the term gonotyl be restricted to a single anatomy, defined as an unbounded, anucleate, typically muscular outgrowth of the wall of the ventrogenital sac, which may bear the genital pore, and which is unarmed in all but one of the genera.

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.
