As they stated themselves, the only way to find out would be the analysis of the living material which was unfortunately no longer available at the time of their publication. We reported this taxon (as

These data indicate that this is typical limno-terrestrial taxon preferring wet moss vegetations in pools, bogponds and lakes with a pH between 5.2 and 7.4 and a low conductivity (<160 µS/cm). These data confirm the final conclusion in
