''Sardinella maderensis'' (Madeiran sardinella) is a species of ray-finned fish in the genus ''Sardinella'' which is found in the Eastern Atlantic and Southeastern Mediterranean. ==Diagnostic features==
''S. madarensis'' is a distinctly elongate ''Sardinella'' while also having a variably protruding belly. These fish have a median number of gill rakers and their upper pectoral fin rays are white on the outer side with a black membrane in between. They are very hard to distinguish from ''Sardinella aurita'' except that these fish have only 7 rays on their pelvic fins and no black spot on the hind part of their gill cover. They also have a gray caudal fin (see Fish anatomy) with black tips.〔
