The results of investigations on the morphology, physiology, pigment c
omposition, light-harvesting antenna and reaction center organization,
and electron carriers of five Erythromicrobium representatives, and o
n phylogenetic relations among them, are summarized. On tbe basis of c
lear phenotypic differences and distinct phylogenetic positions shown
by 16S ribosomal DNA analysis, the tentative species ''Erythromicrobiu
m sibiricum'' and ''Erythromicrobium ursincola'' are formally describe
d as the type species of two new genera: Sandaracinobacter sibiricus g
en. nov., sp. nov., and Erythromonas ursincola gen. nov., sp. nov., re
spectively. The genus Erythromicrobium is at present composed of the t
ypes species, E. ramosum, and two species, ''E. hydrolyticum'' and ''E
. ezovicum,'' whose nomenclature is yet to be validated. All species s
tudied group within the alpha-4 subclass of Proteobacteria.
