Dolomedes plantarius in Belarus 37 ed and we can expect admixture between them. However the consequences are hard to predict. To sum up, if there is a strong intention to save D. plan- tarius in Europe it is essential that not only Belarusian spe- cialists will be involved in investigation of this species within Belarus itself, but all interested legal bodies and scientists ac- ross the Europe.
