is a crayfish endemic to south-eastern Australia and one of the last alien crayfish to be introduced in Italy. In the Laghi di Ninfa Natural Reserve (Latium region, Central Italy), the species was probably introduced in 1999, but only reported for the first time in 2008. Nearby this area, the most widespread alien crayfish is the red swamp crayfish. In the Natural Reserve, between 2008 and 2013 and during spring and summer, crayfish sampling was carried out with baited traps to assess the distribution ofand its possible relationship withwas first recorded in 2008; fewwere detected in the cultivation ponds wherewas present in 2012 and 2013. Moreover, crayfish plague analyses evidenced a positive result in two out of the 12 sampledis now completely absent from the Natural Reserve, whilehas spread in the area and was probably responsible for this eradication sinceis vulnerable to crayfish plague which was also detected in the area. An ecosystem restoration project in the area favoured the spread of.; the implications of this intervention are discussed. View Full-Text
