Cheliomyrmex属的工蚁在新大陆行军蚁（Ecitoninae亚科）中是独一无二的，因为它们的下颚有细长的棘状牙齿。我们提出的第一个猎物记录，这属。Cheliomyrmex andicola捕食大型地面无脊椎动物，也可能捕食脊椎动物。与其他行军蚁不同，C.工蚁用它们的刺捕获猎物工蜂不寻常的下颚和强有力的刺可能分别适用于刺穿和抓住非节肢动物猎物的外皮，以及快速捕获大型猎物。Cheliomyrmex属可能是其他新热带区行军蚁（Echitoninae）的姐妹分类群，Cheliomyrmex与Dorylus属中的旧大陆驱动蚁共享下颌形态和猎物选择特征。大规模合作觅食是行军蚁行为的重要组成部分，可能部分是为了适应利用大型猎物而出现的。
Workers of the genus Cheliomyrmex are unique among the New world army ants (subfamily Ecitoninae) in that their mandibles are armed with elongate, spine‐like teeth. We present the first prey records for this genus. Cheliomyrmex andicola prey on large‐bodied ground dwelling invertebrates and, possibly, on vertebrates. Unlike other army ants, C. andicola workers use their sting during prey capture. The workers' unusual mandibles and potent stings may be adapted for piercing and gripping the integument of nonarthropod prey animals, and for rapidly subduing large‐bodied prey, respectively. The genus Cheliomyrmex may be the sister taxon to other Neotropical army ants (Ecitoninae), and Cheliomyrmex shares features of mandibular morphology and prey selection with Old World driver ants in the genus Dorylus. Mass cooperative foraging, an important element of army ant behavior, may have arisen in part as an adaptation for exploiting large‐bodied prey.
