Abstract: The family Shewanellaceae currently comprises three genera, Shewanella, Parashewanella and Psychrobium, the latter represented by a single species. From the second half of the 1990s, the number of novel species in the Shewanellaceae has steadily increased, suggesting that the true diversity of this family has only begun to emerge. In recent years, efforts to provide a genus-wide, whole genome-based taxonomy for Shewanella have been limited by the lack of numerous type strain genome sequences. To shed light on this question, we sequenced all Shewanella type strains that lacked a publicly available wholegenome sequence. Using state-of-the-art phylogenomic methods, here we provide a genus-wide taxonomy of Shewanella and Parashewanella that resulted in the identification of 48 novel species represented by 73 sequenced isolates, and we propose the correction of 43 misidentified non-type-strain isolates. Our work sets a reference for family-wide comparative genomic studies addressing genetic or ecophysiological aspects of Shewanellaceae, as well as subsequent species descriptions.
