Boreascotia megavesicula n. g., n. sp. (Digenea: Hemiuridae: Lecithochiriinae) in the nototheniid fish Lepidonotothen macrophthalma (Norman) from the sub-Antarctic Atlantic.

摘要

Boreascotia megavesicula gen. et sp. nov. is described and figured from the intestine of Lepidonotothen macrophthalma from the North Scotia Ridge, Sub-Antarctic, Atlantic Ocean. The new genus has an ecsoma, placing it in the family Hemiuridae, and adistinct prostatic vesicle, placing it in the subfamily Lecithochiriinae, but is distinct from the other members of the subfamily in having an elongate, tubular seminal vesicle, which reaches well into the hindbody and overlaps the anterior testis.
