Arcobacter haliotis Tanaka et al. 2017 is a later heterotypic synonym of Arcobacter lekithochrous Diéguez et al. 2017.

The draft whole-genome sequence of Arcobacter haliotis strain LMG 28652T was obtained and compared against the type strain of Arcobacter lekithochrous LFT 1.7T. High similarity was found between the two strains, showing average nucleotide identity and in silico DNA-DNA hybridization values of 98.40 and 86.10 %, respectively. These values indicated that both genomes belonged to the same species, confirming the evidences derived from the phylogenetic analysis performed with the 16S rRNA gene and the concatenated sequences of five housekeeping genes. In addition, the metabolic, physiological and chemotaxonomic features of A. haliotis LMG 28652T were shown to be congruent with those of A. lekithochrous. We conclude that Arcobacter haliotis Tanaka et al. 2017 is a later heterotypic synonym of Arcobacter lekithochrousDiéguez et al. 2017.
