Acanthoponera is a Neotropical genus of ants in the subfamily Ectatomminae. Acanthoponera contains six (one is indeterminate, and one is a morphotaxon) rarely collected species and a fifth unnamed species mentioned by Brown (1958) only known from a stray gyne.

Ectatomminae is a subfamily of ants containing four extant and three extinct genera in two tribes. The subfamily was described in 2003 when Barry Bolton divided the Ponerinae subfamily into six subfamilies. Heteroponerinae used to be an independent subfamily, but was merged into Ectatomminae in 2022. The taxonomical position of Ectatomminae was further upheld in a genomic reanalysis conducted with alternate methods in 2024.

Gnamptogenys is a genus of ants in the subfamily Ectatomminae. The genus has a wide distribution. It is known to occur in the Nearctic, Neotropic, Indomalayan, and Australasian realms. Camacho et al, 2022 revised this genus, significantly reducing its size to only 32 valid extant species and 5 valid fossil species by splitting off most species into four formerly synonymized genera Alfaria, Holcoponera, Poneracantha, and Stictoponera.

Typhlomyrmex is a genus of ants in the subfamily Ectatomminae. Known from the Neotropics, the genus has a wide distribution. Some species are restricted in range, while for example Typhlomyrmex rogenhoferi is known from southern Mexico to northern Argentina. Little is known about their biology. The name "Typhlomyrmex" means "blind ant", as this genus contains only blind ants. Previously classified under the monotypic tribe Typhlomyrmecini, it was merged into Ectatommini in 2022.
