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.
