Prior to this study, 141 species of Tephritidae were known to occur in Italy.
Italian records of nine species of the family Tephritidae (Diptera) are provided. Five species, Eurasimona stigma (Loew, 1840), Noeeta bisetosa Merz, 1992, Campiglossa doronici (Loew, 1856), Xyphosia laticauda (Meigen, 1826) and Rhagoletis berberidis Jermy, 1961 are recorded from Italy for the first time, whereas four species, Inuromaesa maura (Frauenfeld, 1857), Urophora cuspidata (Meigen, 1826), Tephritis conyzifoliae Merz, 1992 and T. mutabilis Merz, 1992, previously recorded in the Fauna Europaea database without reference to collection material, are confirmed and supplemented with host plant data and other collection data.
Diptera, Tephritidae, Italy, checklist, additions
Tephritidae is one of the largest families of cyclorrhaphous Diptera, with almost 5,000 named species predominantly found in the tropics (A. Norrbom, pers. comm.). The family is also referred to as “fruit flies”, as it contains many species that are specialised feeders on fleshy fruit. The tropical regions are true hotspots of tephritid diversity, including hundreds of fruit-eating species, but also species with saprophagous larvae feeding under the bark of fallen trees or in bamboo culms (
Starting from Rondani (
Other relatively recent contributions to the Italian tephritid fauna, including first Italian records, were made by
In this paper, we record five tephritid species for Italy for the first time and confirm the occurrence in the country of four additional species, based on detailed collection data and host plant information obtained during research on symbiotic bacteria of over 30 fruit fly species. The analysis revealed the presence of hereditary symbiotic bacteria in Bactrocera oleae (Rossi, 1790) (
The flies were collected in Italy by the first author, reared from mature larvae and pupae collected together with infested flower heads. Flower heads were detached from their stems and placed in net bags at room temperature to allow the insects to complete their development. An in-field pre-screening of positive samples involved sectioning of the inflorescences and inspection for the presence of larvae or pupae. Adults of Eurasimona stigma (Loew, 1840) were collected with a mouth aspirator while resting on their host plant.
The species were identified using the keys of

We appreciate the assistance of B. Merz in the identification of some species. We thank V. Girolami for his insights during collection of the specimens and L. Marini (University of Padua—DAFNAE) for confirming some host plant identifications.
