By these characteristics it differs from all other species of the genus Actinomyces. It also differs significantly from members of the genera Bacterionema and Propionibacterium. A. propionicus is placed in the new genus Arachnia under the name of Arachnia propionica comb. nov., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/00207713-19-3-267
