Heteronybelinia is a genus of cestodes's order frequently find in fishes with fifteen species described in literature. This study aimed report the presence of cestodes of the genus Heteronybelinia spp. in Pomatomus saltatrix. The fish was purchased from a supermarket in the city of Jau, Sao Paulo, Brazil. The cestode larvae found in the internal organs were collected during necropsy with the aid of a needle, fixed in AFA and identified. These parasites have great hygienic sanitary importance, once some species parasitize fishes' musculature generating negative aspects in their appearance and economic losses in aquaculture. In addition, another well-known aggravating factor is the immunogenic reactions that are currently being studied in fish parasitized with Trypanorhyncha cestodes
