This is the first record of O. melanocephala from chub mackerel and a new geographic record. Four additional larval specimens with developing buccal capsules were found in the chub mackerel examined.engCamallanid nematodesOncophora melanocephalaFishScomber japonicusMadeira Island (Portugal).Faculdade de Ciências da Vidajournal article10.2478/s11686-009-0032-4
