Oxygastra curtisii (Dale, 1834)

Three new populations of

Oxygastra curtisii View in CoL

were discovered, 2 in Latium and 1 in the Molise region ( Table 1 View Table 1 , Fig. 1 View Fig ). All the sites are fast running rivers with a belt of riparian forest. The presence in the southern part of Latium is confirmed for the Liri-Garigliano drainage basin after about 70 years, when it was reported by Castellani (1951). Populations were recorded both in the main Liri river and in its tributary, the Melfa river (FR). Numerous individuals were also observed in Molise (IS) at the Cavaliere river , a tributary of the Volturno, which is part of the ZSC IT7212168 “Valle Porcina - Torrente Vandra – Cesarata”. This finding is in accordance with the abundance of the species in the Volturno drainage area reported by Corso et al. (2019b).
