subFamily
Dolichoderinae
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 Formicinaeand 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 Tapinomini.
