A novel actinomycete, strain A4036T, was isolated from a soil sample collected from the Jabi district in Abuja, Nigeria. The taxonomic position of strain A4036T was established using a combination of genotypic and phenotypic analyses. The organism formed extensively branched substrate and aerial hyphae that generated spiral chains of spores with warty surfaces. The cell wall contained meso-diaminopimelic acid and the cell-wall sugars were glucose, madurose, mannose and ribose. The predominant menaquinone was MK-9(H4). The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylmethylethanolamine, phosphatidylinositol mannoside, hydroxy-phosphatidylethanolamine, hydroxy-phosphatidylmethylethanolamine, two unidentified phospholipids and four unknown glucosamine-containing phospholipids. The major cellular fatty acids were iso-C16 : 0 2-OH, iso-C16 : 0 and 10-methyl C17 : 0. On the basis of 16S rRNA gene sequence similarity studies, strain A4036T grouped in the genus
Nonomuraea
, being most closely related to
Nonomuraea angiospora
IFO 13155T (99.05 %),
Nonomuraea candida
HMC10T (98.78 %),
Nonomuraea kuesteri
GW 14-1925T (98.49 %),
Nonomuraea endophytica
YIM 65601T (98.42 %),
Nonomuraea maheshkhaliensis
16-5-14T (98.40 %),
Nonomuraea turkmeniaca
DSM 43926T (98.38 %),
Nonomuraea helvata
IFO 14681T (98.29 %),
Nonomuraea rubra
DSM 43768T (98.10 %) and
Nonomuraea salmonea
DSM 43678T (98.06 %). Levels of 16S rRNA gene sequence similarity to the type strains of other species of the genus
Nonomuraea
were <98 %. Despite the high 16S rRNA gene sequence similarities, DNA–DNA relatedness values and phenotypic data demonstrated that strain A4036T was clearly distinguished from all closely related species of the genus
Nonomuraea
. Thus, this isolate is considered to represent a novel species of the genus
Nonomuraea
, for which the name Nonomuraea jabiensis sp. nov. is proposed. The type strain is A4036T ( = DSM 45507T = KCTC 19870T).
