The coastal fishes of Madeira Island — new records and an annotated check-list Wirtz, Peter Fricke, Ronald Biscoito, Manuel José Zootaxa 2008 1715 1 26 6249Q 31034 [151,304,1296,1322] Actinopterygii Diodontidae Animalia Tetraodontiformes 20 21 Chordata family  Numerous specimens in the MMF and four specimens in the BMNH belong to this species.   Diodon hystrixLinnaeus, 1758—Spot-fin porcupinefish Tortonese in Whitehead et al.(1986:1347) recorded this species from Madeira. However, the  Diodonspecies at the Canary Islands (Brito et al. 2005) and at the Azores ( Azevedo et al.2004) is  Diodon eydouxiiBrisoutde Barneville, 1846. The presence of  D. hystrixat Madeira therefore appears doubtful and the identity of Madeiran  Diodonneeds checking.
