Abstract
The partial 18S rRNA sequences of E. coelmaticum and E. pancreaticum were amplified using conserved primers and an evolutionary tree was constructed using Neighbor-Joining. The percent identity of Eurytrema species with other Dicrocoeliidae varied from 97.5 to 98.2, while the percent identity between the two Eurytrema species was up to 99.3. The tree showed that E. coelmaticum and E. pancreaticum were not situated in the same position, and they formed one cluster with L. collurioni. These results support a confirmation with molecular data that E. coelomaticum and E. pancreaticum are different species which apparently were not seriously questioned in the past.
