These strains were characterized genetically and phenotypically. Strain Hs20B0-1T was related to Lactococcus piscium DSM 6634T showing 96.3 and 84.2 % sequence similarity in 16S rRNA gene and rpoB gene sequences, respectively. Strain Hs30E4-3T was related to Lactococcus plantarum DSM 20686T showing 94.8 and 82.2 % sequence similarity in 16S rRNA gene and rpoB gene sequences, respectively. The 16S rRNA gene sequence similarity between strains Hs20B0-1T and Hs30E4-3T was 95.7 %. Furthermore, genomic comparisons using pairwise average nucleotide identity (ANI) and digital DNA–DNA hybridization (DDH) analyses between strain Hs20B0-1T and L. piscium DSM 6634T resulted in values of 73.5 and 20.1 %, respectively. Strain Hs30E4-3T had 72.8 % ANI similarity and 21.3 % DDH similarity to L. plantarum DSM 20686T. Strains Hs20B0-1T and Hs30E4-3T had 75.4 % ANI similarity and 21.1 % DDH similarity to each other. The cell-wall peptidoglycan types of strains Hs20B0-1T and Hs30E4-3T were A4α, Lys-Asp and A3α, Lys–Thr–Ala, respectively. The two strains, Hs20B0-1T and Hs30E4-3T, are distinguishable from each other and other established Lactococcus species phylogenetically and phenotypically. In conclusion, two novel species of the genus Lactococcus are proposed, namely Lactococcus insecticola Hs20B0-1T (=JCM 33485T=DSM 110147T) and Lactococcus hodotermopsidis Hs30E4-3T (=JCM 33486T=DSM 110148T), respectively. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.004309
