Abstract: Aneuretus simoni workers have a conspicuous intramandibular gland, formed by round to polygonal class-3 secretory cells with a diameter around 16-17 μm and their accompanying duct cells. Both in minor and major workers, approx. 8 cells open through the proximal upper surface of the mandible, approx. 12 cells open through the proximal lower surface. The secretory cells are characterized by a well-developed granular endoplasmic reticulum and Golgi apparatus. The cytoplasmic organization indicates the secretion has a proteinaceous nature, and therefore probably does not play a pheromonal role. The precise function, however, is not yet known.

Keywords: Aneuretus simoni, Aneuretinae, intramandibular gland, morphology, ultrastructure
