title: Chemical communication in the primitive antAneuretus simoni: The role of the sternal and pygidial glands.
abstract: Trail and alarm communication inAneuretus simoni are mediated by the secretions of the sternal and pygidial glands, respectively. The sternal gland is composed of a glandular epithelium and an associated reservoir located in the 7th sternum. This gland produces a relatively long-lived mass recruitment pheromone. The pygidial gland opens between the 6th and 7th tergites and produces a secretion that releases aggressive alarm. The evolution of glandular physiology in the Aneuretinae and Dolichoderinae are discussed in view of these findings.
