Antarctic representatives of the genus Neolebouria Gibson, 1976 [Digenea, Opecoelidae] with description of one new species

A new fish digenean species, Neolebouria terranovaensis sp. n. (a second representative of this genus in the Antarctic), is described from notothenioids caught in Terra Nova Bay (Ross Sea). New measurements and a figure of N. antarctica (Szidat et Graefe, 1967) are also given. N. terranovaensis sp. n. differs from the latter in smaller dimensions of a body and organs, smaller extent of the cirrus pouch which ends at the level of the ventral sucker and the main habitat, the pyloric caeca. In contrast, N. antarctica occurs along the whole intestine.
