Abstract

In this short communication, we report the unusual presence of blind specimens of the non-native Gammarus roeselii Gervais 1835 (Amphioda, Gammaridae) in the sub-lacustrine Ticino River basin (Po River floodplain, Northern Italy). Considering that G. roeselii is present in almost all small semi-natural tributaries of the Ticino River, it is important to carry out further research on this well-established exotic species to verify its genetic variability.

Keywords
