sp. nov., a gut symbiont of the bordered plant bug .

Gram-negative, aerobic, rod-shaped, non-spore-forming, motile bacteria, designated strains F2 and PGU16, were isolated from the midgut crypts of the bordered plant bug , collected in Okinawa prefecture, Japan. Although these strains were derived from different host individuals collected at different times, their 16S rRNA gene sequences were identical and showed the highest similarity to MWAP64 (99.3 %). The genome of strain F2 consisted of two chromosomes and two plasmids, and its size and G+C content were 9.28 Mb and 62.4 mol% respectively; on the other hand, that of strain PGU16 consisted of two chromosomes and three plasmids, and its size and G+C content were 9.47 Mb and 62.4 mol%, respectively. Phylogenetic analyses revealed that these two strains are members of the genus . The digital DNA-DNA hybridization value between these two strains was 92.4 %; on the other hand, the values between strain F2 and MWAP64 or phylogenetically closely related species were 44.3 % or below 49.1 %. The predominant fatty acids of both strains were C, C cyclo, summed feature 8 (C 7/C 6), and C cyclo 8, and their respiratory quinone was ubiquinone 8. Based on the above genotypic and phenotypic characteristics, strains F2 and PGU16 represent a novel species of the genus for which the name sp. nov. is proposed. The type strain is F2 (=NBRC 115765=LMG 32765).
