<jats:p>A novel actinobacterium, designated strain C4-31<jats:sup>T</jats:sup>, was isolated from soil collected from a cave. Cells were aerobic, Gram-reaction-positive, oxidase-negative, catalase-positive and non-motile cocci. Comparison of 16S rRNA gene sequences showed that the organism occupied a distinct phylogenetic position within the suborder <jats:italic>Frankineae</jats:italic>, with sequence similarity values of less than 93.2 % to members of this suborder. The diagnostic diamino acid in the cell-wall peptidoglycan was <jats:italic>meso</jats:italic>-diaminopimelic acid. The major menaquinone was MK-9(H<jats:sub>4</jats:sub>). The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannoside, an unknown aminophospholipid and an unknown phospholipid. The major fatty acids were iso-C<jats:sub>16 : 0</jats:sub>, C<jats:sub>17 : 1</jats:sub>ω6<jats:italic>c</jats:italic> and C<jats:sub>16 : 0</jats:sub>. The G+C content of the DNA was 62.8 mol%. On the basis of morphological and chemotaxonomic data as well as phylogenetic evidence, strain C4-31<jats:sup>T</jats:sup> ( = KCTC 39556<jats:sup>T</jats:sup> = DSM 100065<jats:sup>T</jats:sup>) is considered to represent the type strain of a novel species of a new genus in the suborder <jats:italic>Frankineae</jats:italic>, for which the name <jats:italic>Antricoccus suffuscus</jats:italic> gen. nov., sp. nov. is proposed.</jats:p>
