The newly discovered subspecies E. jutsonii Maiden subsp. kobela D.Nicolle & M.E.French is described, differing from the typical subspecies in the narrower adult leaves, the generally more slender flower buds with a more pointed operculum and the slightly smaller fruits. The new subspecies is disjunct from the typical subspecies by over 400 kilometres and is known from a single site spanning approximately five kilometres. Eucalyptus jutsonii subsp. kobela may be under threat from mining-related activity and the subspecies meets the criteria for listing as Priority One under the Conservation Codes for Western Australian Flora. A key to E. ser. Micrantherae is included.
