The families Jonesiaceae, Ruaniaceae, and Bogoriellaceae

Abstract

All three families are members of the order Micrococcales (Busse 2012). As such they are Gram-positive, not acid-fast, do not form endospores, and do not contain mycolic acids in their cell wall. Jonesiacea is a monogeneric family and contains two species, J. denitrificans and J. quinhaiensis. Ruaniaceae encompasses two monospecific genera, Ruania and Haloactinobacterium, while Bogoriella embraces the monospecific genus Bogoriella and Georgenia for which six species have been described. Phylogenetic neighbors are the families Bogoriellaceae, Ruaniaceae, Beutenbergiaceae, and Actinomycetaceae. The rationale for treating these three neighboring genera in one chapter but omitting Actinomycetaceae is the fact that the latter family contains seven genera with more than 50 species, deserving a chapter on its own. Except for Jonesia denitrificans, a former member of the genus Listeria, hardly any information is available for other species of these families besides their original description.
