A novel filamentous actinobacterium, designated strain DHS C013^T, was isolated from limestone collected in Guizhou Province, South-west China. Morphological and chemotaxonomic characteristics of the strain support its assignment to the genus Lentzea. Phylogenetic analyses showed that strain DHS C013^T is closely related to Lentzea jiangxiensis FXJ1.034^T (98.7 % 16S rRNA gene similarity) and Lentzea flaviverrucosa 4.0578^T (98.0 % 16S rRNA gene similarity), but it can be distinguished from these strains based on low levels of DNA:DNA relatedness (~44 and ~37 %, respectively). Physiological and biochemical tests also allowed phenotypic differentiation of the novel strain from these closely related species. On the basis of the evidence presented here, strain DHS C013^T is concluded to represent a novel species of the genus Lentzea, for which the name Lentzea guizhouensis sp. nov. is proposed. The type strain is DHS C013^T (=KCTC 29677^T = CGMCC 4.7203^T).
