Fig. 9 Morphological and molecular delimitation of five Trichodina species isolated from freshwater invertebrates collected in Slovakia. A Principal component analysis of 39 individuals based on 12 morphometric features. Eigenvalues of the first two ordination axes are λ1=6.899 and λ2 =3.023, explaining 84.08% of the total variation. Although Trichodina species isolated from bivalves and nerites could be unambiguously differentiated from each other, morphometric data per se were not sufficient to delimit the three
