Although rarely encountered, D. albamaculus is widespread across semi-arid southern Australia, occurring from the Western Australian coast to eastern South Australia. It has been found in open scrub and Acacia woodland habitats.

Identification

Pale markings present near lower margin of eye; sculpturing on head consisting of large, shallow to moderately deep fovea; pronotum and propodeum lacking spines; posterior face of the propodeum strongly concave, separated from the dorsal face by a distinct carina; dorsum of propodeum weakly convex and elongate (longer than posterior); pubescence on first gastral tergite sparse, the individual hairs generally not overlapping, or hairs absent.

This species is easily confused with Dolichoderus semiorbis. It can be distinguished from this species by the presence of erect or suberect hairs on the tibiae and the more distinctive carina protruding upwards separating the dorsal and posterior face of the propodeum.
