To date, the ‘marbled crayfish’, Procambarus fallax (Hagen, 1870) f. virginalis, in Italy has been reported only from Tuscany (central Italy). Recently, specimens of this alien American crayfish were found in the Po di Maistra Channel, Porto Tolle, south of Venice (northern Italy). The identification of this species was confirmed by its external morphology and colour pattern, as well as by molecular analysis. The present report provides the second record for the marbled crayfish in Italy.

L’ « écrevisse marbrée » Procambarus fallax (Hagen, 1870) f. virginalis a été précédemment signalée en Italie seulement en Toscane (Italie centrale). Récemment, des spécimens de cette écrevisse exotique ont été trouvés dans le canal du Po di Maistra, Porte Tolle, sud de Venise (Italie du nord). L’identification de cette espèce a été confirmée par sa morphologie externe et sa couleur, ainsi que par des analyses moléculaires. Le présent rapport fournit la deuxième observation pour l’écrevisse marbrée en Italie.
