A novel aerobic actinomycete, designated as HA15955 T , was isolated from a mangrove mud sample collected in Sanya, China. Scanning electron microscopy revealed that HA15955 T produced straight to spiral spore chains with smooth cylindrical spores. 16S rRNA gene sequence similarity showed that strain HA15955 T belonged to the genus Streptomyces, was most closely related to Streptomyces speibonae NRRL B-24240 T (98.7 % similarity) and formed a distinct subclade. The low relatedness value of DNA-DNA hybridization showed that it formed a distinct genomic species. Based on phenotypic, genotypic and phylogenetic data, strain HA15955 T should be classified as a novel species of the genus Streptomyces, for which the name Streptomycescaeni sp. nov. is proposed. The type strain is HA15955 T (=CGMCC 4.7426 T =DSM 105693 T ).
