DESCRIPTIONOF COMPANILACTOBACILLUS METRIOPTERAE COMB. NOV.

Companilactobacillusmetriopterae (me.tri.o.pte’rae. N.L. fem. gen. n. metriopterae of Metrioptera, thegenus 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 thesmallest 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.
