| Abstract: | The karyotypes of three species of digeneans belonging three families were stu-died through the chromosome metaphases prepared from spermatogenous cells bythe air-drying technique. Gigantodiscum ranae had 20 chromosomes in diploid nu-mber, Its karyotype comprised 8 pairs of metacentrics (m) and 2 pairs of subme-tacentrics (sm). Haematoloechus nanchangensis possessed chromosomes of 2n=22.There were 7 pairs of metacentrics (m), 3 pairs of submetacentrics (sm) and onepair of subtelocentrics (st) in its karyotype. The diploid number of Lyperosomumkronschenpi was also 22 and had a chromosome formula of N=+3m+7st+1t,Some problems concerning the cytotaxonomy and phylogenetic relationships inTrematoda were discussed. |
