An overview on Sardinia's soft ticks (Ixodida: Argasidae).

Knowledge about soft ticks (Ixodida: Argasidae) in Sardinia is incomplete and distribution data need to be updated. This work studies soft ticks on the island focusing on two species, Argas reflexus and Ornithodoros maritimus, both recently recorded. A total number of 12 specimens of these species of interest were collected between 2004 and 2015. This study reports for the first time the presence of O. maritimus in a coastal area in Italy, and more generally in a coastal area rather than small islands near the coastline, confirming the presence of this species on the island 20 years after its last recording. Moreover we confirm the presence of A. reflexus on the island, in the town of Cagliari and, for the first time, in the town of Quartu Sant'Elena. At the present state of knowledge, in Sardinia, Ornithodoros erraticus, which was actively looked for within the surveillance for African swine fever, an endemic disease since 1978 on the island, is not present. The presence of another species reported only once in Sardinia, Argas vespertilionis, needs further confirmation.
