Abstract


Populations of X. diversicaudatum, X. italiae, X. pachtaicum, X. simile, X. taylori and X. vuittenezi from Slovakia are in the range of specific descriptions and populations of X. italiae, X. taylori and X. vuittenezi show inter and intrapopulation low variability for most of the diagnostic characters. Isoelectrofocusing superoxide dismutase profiles seem appropriate and efficient in separating species. Unequivocable specific identification can also be achieved by ribosomal DNA examination, but amplification does not always occur.
