A chromosome study in the progenetic cestode Cyathocephalus truncatus (Cestoda: Spathebothriidea)

The chromosomes of somatic cells of progenetic Cyathocephalus truncatus, parasite of amphipod crustaceans, Gammarus lacustris, from North-West Chukotka were investigated using standard Giemsa staining. The karyotype, not described previously, consists of 9 pairs of chromosomes (2n=18), the most wide...
