title: [Description of Hymenolepis cerberensis n. sp. (Cestoda: Hymenolepididae) and first general considerations on the fauna of cestode parasites of the pygmy shrew Suncus etruscus (Savi, 1822) (Insectivora: Soricidae)].
abstract: Description and differentiation of the adult stage of Hymenolepis cerberensis n. sp. (Cestoda: Hymenolepididae), an intestinal parasite of the Pygmy white-toothed shrew, Suncus etruscus (Savi, 1822) (Insectivora: Soricidae: Crocidurinae) in the region of Banyuls-sur-Mer and Cerbère (Oriental Pyrenees, France). The new species is characterized by the size of the gravid specimens and by the presence of 18-21 rostellar hooks of 18.5-20 micron and of filaments around the embryophore. The general composition of the fauna of Cyclophyllidea parasitizing S. etruscus is analysed. There are three less specialised Hymenolepis species with a scolex of the same type and one Pseudhymenolepis species, with the absence of unarmed species lacking a rostrum. The oioxenous character of the Cestodes parasitizing Suncus species sustains the validity of the genus Suncus. The resemblance of the Cestodefaunas suggests a narrow phyletic relationship between the genera Suncus and Crocidura.
