Specimens of Dolichoderus abruptus have a heart-shaped head, poorly formed propodeal angles and a petiole with two well-developed teeth. It has numerous long, erect hairs, but a small amount of short, fine hairs (pubescence). It also has a smooth, shiny gaster.cite-ref-0-2-0[2]

Dolichoderus abruptus is similar to Dolichoderus ferrugineus in color, hair and pubescence arrangement, but differs in its smooth and shiny gastrula, which is slightly spotted in the case of ferrugineus.cite-ref-0-2-1[2]

It can also be confused with dolichoderus quadridenticulatus due to the shape of its head and its size, but it can be distinguished by its lighter, golden color.cite-ref-0-2-2[2]
