Ponerinae is a subfamily of ants in the Poneromorph subfamilies group, with about 1,600 species in 47 extant genera, including ''Dinoponera gigantea'' - one of the world's largest species of ant. They are most easily identified from other subfamilies by a constricted gaster (abdomen). They are rare examples of stinging ants.〔Hoffman, Donald R. "Ant venoms" Current Opinion in Allergy and Clinical Immunology 2010, vol. 10, pages 342-346. 〕 ==Identification== Workers of this subfamily can be distinguished by the following traits: # The outer borders of the frontal lobes form short semicircles or triangles, and have a pinched-in appearance posteriorly. # The promesonotal suture is flexible. # A constriction is present between abdominal segments 3 and 4, but segment 3 is not markedly reduced in size compared to segment 4 (i.e., postpetiole absent). # Abdominal segments 3 and 4 exhibit tergosternal fusion. # The sting is well developed.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「ponerinae」の詳細全文を読む スポンサード リンク
