In August 2007, 856 specimens of Echinogammarus tibaldii Pinkster et Stock, 1970 from the Lake Piediluco (Central Italy) were collected from 3 different sites and examined for larval helminths. Fourteen amphipods (1.63%) were infected with larvae of Lateriporus teres (Dilepididae) and one amphipod (0.12%) was infected with Microsomacanthus microsoma (Hymenolepididae). Adults of both species are known from waterfowl and gulls. The present results constitute new host records for both cestode species and the first finding of L. teres in Italy.
