Acanthostichus

Acanthostichus is a predatory and predominantly subterranean genus of ant in the subfamily Dorylinae.[2][3] They are found in the New World, from the southern United States to Uruguay, Paraguay and northern Argentina.[4] They are probably common, but due to their subterranean nature, they are seldom collected or seen.[5]

Most species are very similar; the petiole is the most important feature in identifying species. Many are known only from a few collections, or even single specimen, which makes it hard to determine variability within species. For this reason, many described members of this genus may be synonyms.[5]
