The original version of this Article contained errors. Illumina sequencing of the DNA extract of Myxobolus pupkoi led us to discover that the host of this species is not Chelon ramada, but rather C. labrosus. The morphological identification error stemmed from the fact that C. labrosus is extremely rare in the Sea of Galilee, and thus its identification was overlooked. We only sequenced the COI gene of a single fish specimen among the 23 fish sampled to confirm the morphological identification. Unlike C. ramada, C. labrosus was never voluntarily introduced to the Sea of Galilee, but rather was a hitchhiker introduced together with C. ramada1. In absence of reproduction in the lake, its population size is very small1. We assembled the complete mitochondrial genome of C. labrosus from the Illumina data obtained from the sequencing of the M. pupkoi sample (deposited under accession OX417109). We also confirmed using PCR amplifications that the fish host of M. exiguus studied in our work is C. ramada (deposited under accessions OX417110-1). This misidentification that we here correct does not affect the main conclusions of our manuscript. Like C. ramada, C. labrosus is an alien species and its infection took place in the Mediterranean Sea, where the fingerlings were caught. Additionally, the differences in spore morphology between M. pupkoi and other Myxobolus parasites of the genus Chelon warrant the description of a new species. The authors apologize for the misidentification and any confusion caused.
