A new strategy of endosymbiont midgut bacteria in ant (Ponerinae)
Micron, 2010The location and ultrastructure of bacteria associated with microvilli in the midgut of Odontomachus bauri were examined by transmission electron microscopy. These filamentous type bacteria are the second morphotype described in the midgut of this ant. They colonizes only the ectoperitrophic space, more specifically attaching along microvilli.

Ecology and behavior ofGnamptogenys horni (Formicidae: Ponerinae)
Insectes Sociaux, 1994In order to examine social behavior in the little-studied ponerine ant genusGnamptogenys, detailed observations were made on captive colonies ofG. horni. Compilation of a behavioral repertory gave evidence of age-based division of labor, with old ants more likely to forage and young ants more likely to tend brood.

Comparative Survey of Abdominal Gland Secretions of the Ant Subfamily Ponerinae
Journal of Chemical Ecology, 2003The chemical contents of three abdominal glands were investigated in representative species of the ponerine ants. The Dufour glands of 14 species show a wide variety of contents. In Mystrium camillae and Proceratium itoi, no volatile substances were found in either the Dufour or venom glands.
