title: Keys to the species of Neolebouria Gibson, 1976 (Digenea: Opecoelidae: Plagioporinae), with a redescription of Neolebouria truncata (Linton, 1940).
abstract: Three keys to the species of Neolebouria Gibson, 1976, representing three body types, are provided based on the location of the genital pore relative to the intestinal bifurcation. These are: the lanceolata body type, where the genital pore is clearly prebifurcal; the diacopae body type, where the genital pore is located at or near the level of the intestinal bifurcation; and the maorum body type, where the genital pore is clearly postbifurcal. Fifteen species were assigned to the lanceolata body type; eight species to the diacopae body type; and four species to the maorum body type. Neolebouria truncata (Linton, 1940) is redescribed and N. georgiensis Gibson, 1976 is reinstated as a valid species. Neither N. georgiensis, nor N. antarctica Szidat & Graefe, 1967 (syn. Crassicutis antarcticus Szidat & Graefe, 1967), as described by Zdzitowiecki et al. (1993), represent N. antarctica, as originally described, and N. georgiensis and N. antarctica, as described by Zdzitowiecki et al. (1993), may be conspecific.
