EOL Text

Introduction:

The Dolichoderinae share the following characters with the Aneuretinae and Formicinae (Bolton 2003):

  • Dorsal cuticular flap of the metapleural gland anteriorly reduced and posteromedially extended
  • Petiole with complete tergosternal fusion
  • Postpygidial glands absent

Synapomorphies of the Dolichoderinae are listed by Bolton (2003):

  • Slit-like junction of pygidium and hypopygium
  • Sting vestigial
  • Pygidial glands producing cyclopenanoid monoterpenes (iridoids)
  • Larvae with reduced hairs
  • Reduced (sensilliform) larval maxillary palp and galea
  • Small larval sericteries and reduced larval neck

SUBFAMILY DOLICHODERINAE HNS FOREL

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 Formicinae HNS 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 Tapinomini HNS .

Dolichoderinae:

Dolichoderinae is a subfamily of ants, which includes species such as the Argentine ant (Linepithema humile), the erratic ant, the odorous house ant, and the cone ant. The subfamily presents a great diversity of species throughout the world, distributed in different biogeographic regions, from the Palearctic, Nearctic, Afrotropical region and Malaysia, to the Middle East, Australian, and Neotropical regions.[2]

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.[3]

Of the compounds produced by dolichoderine ants, several terpenoids were identified including the previously unknown iridomyrmecin, isoiridomyrmecin, and iridodial.[4] Such compounds are responsible for the smell given off by ants of this subfamily when crushed or disturbed.[citation needed]
