Remarks. In Slovakia, S. distinca dwells in a very wide variety of environmental conditions: elevation: 151– 1453 m, pH: 5.3–9.2, conductivity: 9–580 µS.cm -1. The species is occasionally found in sympatry with S. striata.

Distribution. Sigara distincta is widespread in Europe, Siberia and north Africa, but is lacking in the southwestern part of Europe ( Jastrey 1981, Nieser 1982). This species tolerates a wide range of habitats but prefers stagnant waters in higher elevations with low pH (5−6) and conductivity (<200 µS.cm -1) ( Mercken 1989, Lock et al. 2013).
