Redescriptions of Monopylidium exiguum (Dujardin, 1845) and M. albani (Mettrick, 1958) n. comb. (Cestoda: Dilepididae) from European passerine birds.

ABSTRACT

Two species of Monopylidium Fuhrmann, 1899 are redescribed on the basis of specimens from their type-hosts M. exiguum (Dujardin, 1845) from Troglodytes troglodytes L. (Passeriformes Troglodytidae) on the Curonian Spit, Kaliningradskaya Oblast', Russia, and M. albani (Mettrick, 1958) n. comb. (originally Paricterotaenia albani Mettrick, 1958) from Sturnus vulgaris L. (Passeriformes Sturnidae) in the Canton of Jura, Switzerland. In contrast to the previously proposed synonymy of these two species (Spasskaya & Spasskii, 1977), they are recognised as distinct and M. albani is revalidated.
