Seven genotypically distinct strains assigned to the genus were isolated in different laboratories from several animal sources. Strain D17_0559-3-2-1 and three further strains were isolated from samples of duck, pig and goose. The strains had >99 % 16S rRNA gene sequence similarity to each other and to strain VA92-K48 and two further strains isolated from samples of medical leech and a turtle. The closest related type strains to the seven strains were those of (96.74 %) and (95.93 %). Average nucleotide identity, amino acid identity and DNA-DNA hybridization results showed that the strains represented two separate novel species. One further phylogenetically distinct strain (165301687) was isolated from fox urine. The strain had highest 16S rRNA gene sequence similarity to the type strains of (95.67 %), followed by (95.58 %) and (94.22 %) and represented a further novel species. Chemotaxonomic and physiological data of the novel strains were assessed, but failed to unequivocally differentiate the novel species from existing members of the genus. MALDI-TOF MS data proved the discrimination of at least strain 165301687 from all currently described species. Based on the presented phylogenomic and physiological data, we propose three novel species, sp. nov. with strain D17_0559-3-2-1 (=DSM 111258= CIP 111884=CCM 9044) as type strain, sp. nov. with strain VA92-K48 (=DSM 106012=LMG 30351=CIP 111492) as type strain and sp. nov. with strain 165301687 (=DSM 106013= LMG 30352= CIP 111494) as type strain.
