Abstract

Karyotypes of three species of Bothriocephalus were studied using conventional Giemsa staining and comparative karyometric analysis. Bothriocephalus claviceps and Bothriocephalus gregarius showed a karyotype with 2n = 14 chromosomes. All chromosomes of B. claviceps were biarmed, metacentric or meta-submetacentric. The two first pairs of homologues were markedly larger than the remaining elements and represented 48.62 % of the total chromosome length. The karyotype of B. gregarius had similar metric values for the chromosomes, but clearly differed in the chromosome morphology of pairs 5, 6 and 7, which had terminally located centromeres. The diploid number 2n = 12 was found in B. scorpii. The karyotype consists of five pairs of metacentric and one pair of submeta–metacentric chromosomes. The possible pathways of karyotype evolution within Bothriocephalus spp. and their phylogenetic relations with the other karyologically studied groups in the order Pseudophyllidea are discussed.
