A taxogenomic study of three strains (3986T, 51.81, and JF 2415) isolated from rabbits between 1972 and 2000 led to the description of a new Neisseria species. The highest sequence similarity of the 16S rRNA gene was found to Neisseria animalis NCTC 10212T (96.7 %). The 16S rRNA gene similarity above 99 % and average nucleotide identity (ANI) values above 96 % among the strains, indicated that they belong to the same species. At the same time, the strains shared ANI values below 81 % and dDDH values below 24 % with all described Neisseria species. In the bac120 gene phylogenetic tree, the three strains clustered near Neisseria elongata and Neisseria bacilliformis in the Neisseria clade. However, the Neisseria clade is not monophyletic, and includes the type strains of Morococcus cerebrosus, Bergeriella denitrificans, Kingella potus, Uruburuella suis, and Uruburuella testudinis. Neisseria shayeganii clustered outside the clade with members of the genus Eikenella. Amino acid identity (AAI) values were calculated, and a threshold of 71 % was used to circumscribe the genus Neisseria. According to this proposed AAI threshold, strains 3986T, 51.81, and JF 2415 were placed within the genus Neisseria. The cells of the three strains were Gram-stain-negative diplococcobacilli and non-motile. Optimal growth on trypticase soy agar occurred at 37 °C and pH 8.5 in aerobic conditions. Notably, all strains exhibited indole production in the API-NH test, which is atypical for Neisseria and the family Neisseriaceae. The strains exhibited a common set of 68 peaks in their MALDI-TOF MS profiles, facilitating the swift and accurate identification of this species. Based on genotypic and phenotypic data, it is proposed that strains 3986T, 51.81, and JF 2415 represent a novel species within the genus Neisseria, for which the name Neisseria leonii sp. nov. is proposed (type strain 3986T=R726T=CIP 109994T=LMG 32907T).

“…A previous report on the status of taxonomic subcommittees [2] identified 14 that were active and 17 considered inactive as a consequence of a lack of demonstrable activity for protracted periods of time (10 years or more with no meetings held) and/or no identifiable Chairperson. Upon the election of the 2020 ICSP Executive Board, the current Secretary for Subcommittees was charged with investigating the current state of taxonomic subcommittees.…”

“…It remains the case that many subcommittees dissolved due to inactivity [2] have not been reactivated, despite the considerable activity of researchers worldwide across the depth and breadth of prokaryotic taxonomy evidenced from myriad publications in the International Journal of Systematic and Evolutionary Microbiology and indeed other microbiology journals. There is a continued need for collaboration and cooperation in many areas of microbial taxonomy and systematics, and subcommittees can play a key role in serving the wider scientific community to provide sound guidelines and solid definitions.…”
