The genus <i>Terribacillus</i> includes four species with validly published names, <i>Terribacillus aidingensis, T. goriensis, T. halophilus</i> and <i>T. saccharophilus</i>. The type species <i>T. saccharophilus</i> 002-048^T (=IAM 15309^T=KCTC 13936^T) was isolated from the soil in Japan, while <i>T. goriensis</i> CL-GR16^T (=KCCM 42329^T=DSM 18252^T) was isolated from the coastal water off the east coast of Korea. Both strains have similar phenotypic and chemotaxonomic characteristics. Anteiso-C_{15 : 0} was the major fatty acid, followed by anteiso-C_17 : 0 and iso-C_15 : 0. There were similar major menaquinones (MK-7). As determined by whole-genome sequencing, the DNA G+C content of 42.53 and 42.66 mol% was found for <i>T. saccharophilus</i> and <i>T. goriensis</i>, respectively, and they were 99.86% identical in their 16S rRNA gene sequences (1,421 bp). Genomic comparisons showed the average nucleotide identity was 98.29% and 84.80% for digital DNA-DNA hybridization. These values exceeded the threshold values for bacterial species delineation. Using the Type (Strain) Genome Server, both species were identified as <i>T. saccharophilus</i>.
