White seabream <i>Diplodus sargus</i> (L.) is a commercially valuable sparid fish reared in Southern European aquacultures. Nonetheless, knowledge on myxosporean infections potentially harming the sustainable production of this fish is extremely limited. In this study, a myxosporean survey was conducted on <i>D. sargus</i> specimens reared in two Southern Portuguese fish farms. Two coelozoic myxosporeans were detected infecting the gall bladder, and are herein reported based on microscopic and molecular procedures: <i>Ceratomyxa sargus</i> n. sp. and <i>Zschokkella auratis</i> Rocha et al., 2013, previously descPeerJOccurrence of two myxosporean parasites in the gall bladder of white seabream <i>Diplodus sargus</i> (L.)
