In present study, the morphology and species identification of the Neobenedenia parasites (Isolate Batam/IB) in the cage aquaculture were studied via morphological and molecular marker methods at Batam Island, Indonesia. The isolate Batam is morphological similar with Neobenedenia girellae, and it is considered to belong to the Neobenedenia genera. 394 bp of the 28S rRNA was amplified, and its similarity with other genera was between 85.86%−99.47%. The phylogenetic tree shows that IB, Neobenedenia melleni and Neobenedenia girellae are in a same cluster, and other Benedeniinae species form their own cluster. To sum up, IB is identified as the specie of Neobenedenia girellae and we support the theory that N. melleni and N. girellae are synonyms.
