Abstract The large paired reservoirs of the pygidial gland of Azteca nr. bicolor and A. chartifex represents the largest exocrine structure in the abdomen. The glands produce a secretion with a strong smell, which the ants release when they are disturbed. Analyses of the secretions by gas chromatography–mass spectrometry (GC-MS) revealed a mixture of iridoids and ketones. A. nr. bicolor contains 2-heptanone (8%) and a mixture of three iridodial isomers, with trans-trans-iridodial as the major component (32%). A. chartifex contains 6-methyl-5-hepten-2-one (13%) and the three isomeric iridodials with cis-trans-iridodial as the principal component (32%).
