Ornithomya palmae species nova (Diptera: Hippoboscidae) a new species of louse fly from the Canary Islands

A new species of louse fly in the genus <i>Ornithomya</i> Latreille, 1802 (Diptera: Hippoboscidae) <i>Ornithomya palmae</i> sp. n. is described from the island of La Palma in the Canary Islands. Unlike other species of <i>Ornithomya</i>, this species has a series of horizontal ridges running across the scutellum. Otherwise, the most obvious differences between <i>O. palmae</i> sp. n. and the most closely related species <i>Ornithomya chloropus</i> Bergroth, 1901 are the arrangement of the wing veins and the lack of dark markings on the lateral gena and mesothoracic basisternum in the new species.
