In 2016, division of the genus Propionibacterium into four distinct genera was proposed. As a consequence, the species Propionibacterium acnes was transferred to Cutibacterium gen. nov. as Cutibacterium acnes comb. nov. The three recently proposed subspecies of P. acnes were not, however, accommodated in this proposal. Following a very recent validation of a new combination for C. acnessubsp.defendens and an automatically created C. acnessubsp.acnes, we now propose the new combination, C. acnessubsp. elongatum comb. nov. The type strain of Cutibacterium acnes subsp. elongatum is JCM 18919T (=NCTC 13655T). On the basis of further genomic and phenotypic (haemolysis and MALDI-TOF mass spectrometry) analyses of these subspecies, we also provide emended descriptions of the genus Cutibacterium Scholz and Kilian 2016, C. acnessubsp.acnes (Gilchrist 1900) Nouioui et al. 2018, and C. acnessubsp.defendens (McDowell et al. 2016) Nouioui et al. 2018.
