Dolichoderus niger is restricted to low mallee and scrub habitats across southern Western Australia. It has been collected only a handful of times, including in relictual native woodlands in the Perth metropolitan area (Heterick, 2009).
Pronotum rounded, lacking spines; propodeum with elongate spines which are directed upward at an angle less than 45° to the horizontal plane, in dorsal view the spines with an angle of at least 90° between their bases and this region forming a "V" with a narrowly rounded angle; dorsum of petiolar node angular; legs long and uniformly coloured dark red-brown to reddish-black.
This species most closely resembles Dolichoderus rufotibialis but can be distinguished by the uniformly coloured legs in D. niger compared to the bi-coloured legs found in D. rufotibialis, with its dark femora and lightly coloured tibiae.
