Abstract

A karyometric analysis of the chromosome set of the marine turbellarians Monocelis fusca, M. lineata and Parotoplana macrostyla has been carried out. The karyotype of the two Monocelis species investigated (2n=6) is formed by three pairs of small and similarly sized chromosomes: In M. fusca, chromosome 1 is metacentric, chromosome 2 acrocentric and chromosome 3 is subtelocentric.M. lineata also presents one pair of metacentric chromosomes (chromosome 2), while chromosomes 1 and 3 are submetacentric. P. macrostyla (2n=12) reveals two pairs of large metacentric and four pairs of small chromosomes, three of which are metacentric, whereas the last is subtelocentric.
