Characterization and identification of strain CW 1 ( = JCM 17161) isolated from corn silage were performed. Strain CW 1 was a Gram-positive, catalase-negative and homofermentative rod that produced the -form of lactic acid. This strain exhibited more than 99.6 % 16S rRNA gene sequence similarity and greater than 82 % DNA–DNA reassociation with type strains of , and . To clarify the taxonomic positions of these type strains, phenotypic characterization, 16S rRNA gene sequencing, ribotyping and DNA–DNA relatedness were examined. The three type strains displayed different -arabinose, lactose, melibiose, melezitose, raffinose and -acetyl-β-glucosaminidase fermentation patterns. Phylogenetic analysis showed that is a closer neighbour of and , sharing 99.5–99.9 % 16S rRNA gene sequence similarity, which was confirmed by the high DNA–DNA relatedness (≥82 %) between JCM 10415, JCM 16180 and JCM 10707. Therefore, it is proposed that and should be reclassified as later synonyms of
