This subfamily is distinguished by having a single petiole (no post-petiole) and a slit-like orifice, from which chemical compounds are released, rather than the round acidopore encircled by hairs that typifies the family to which it belongs, Formicidae. Dolichoderine ants do not possess a sting, unlike ants in some other subfamilies, such as Ponerinae and Myrmicinae, instead relying on the chemical defensive compounds produced from the anal gland.
Of the compounds produced by dolichoderine ants, several terpenoids were identified including the previously unknown iridomyrmecin, isoiridomyrmecin, and iridodial. Such compounds are responsible for the smell given off by ants of this subfamily when crushed or disturbed.

This subfamily includes fifteen genera with the greatest number of species distributed through the tropics. The sting is vestigial or absent but many species have poison glands that excrete a repellent fluid through the anal orifice. The gaster has a reduced number of segments compared with FormicinaeHNS and Ponerinae of which four only are visible in dorsal view in the female castes and five in the males. Pupae are not protected by cocoons. The two genera treated here both belong in the tribe TapinominiHNS .
