Eleven opisthobranch species (1 Cephalaspidea and 10 Nudibranchia) collected on the southern and western coasts of Portugal are reported for the first time from the Portuguese continental coasts: Chelidonura africana Pruvot-Fol, 1953, Trapania orteai García-Gómez & Cervera, 1989, Polycera aurantiomarginata García-Gómez & Bobo, 1984, Thecacera pennigera (Montagu, 1815), Doris sticta (Iredale & O'Donoghue, 1923), Discodoris atromaculata (Bergh, 1880), Dendrodoris herytra Valdés & Ortea, 1996, Hancockia uncinata (Hesse, 1872), Doto millbayana (Lemche, 1976), Favourinus blianus Lemche & Thompson, 1974 and Eubranchus doriae (Trinchese, 1874). Two families (Aglajidae and Hancockiidae) and three genera (Chelidonura, Thecacera and Hancockia) are new records for the Portuguese opisthobranch fauna. For each species, descriptions of external features and colour photographs are provided and the geographical distribution, external morphology and aspects of ecology are discussed.
