NOV. Companilactobacillus metriopterae (me.tri.o.pte’rae. N.L. fem. gen. n. metriopterae of Metrioptera , the genus of grasshoppers from which the type strain was isolated). Basonym: Lactobacillus metriopterae Chiba et al. 2018, 1486 VP ; the species includes strains previously described as Lactobacillus terrae Kim et al. 2018 [ 135 , 136 ] C. metriopterae forms an outgroup of Companilactobacillus and has the smallest genome size (1.50 Mbp) and mol% G+C content (32.8); it seems to transition to an insect associated lifestyle. C. metriopterae is pigmented and ferments fewer carbohydrates than other companilactobacilli. Isolated from the gut of grasshopper Metrioptera engelhardti , other isolates were obtained from soil. The type strain is Hime 5-1 T = JCM 31635 T = DSM 103730 T . Genome sequence accession number: RSTD00000000. 16S RNA gene sequence accession number: LC190736 .
