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.
