Diversity [1]
16 species

Lachnomyrmex is a Neotropical genus of ants in the subfamily Myrmicinae. [2] The genus consists of 16 species restricted to the Neotropics, known from southern Mexico to northern Argentina (and Trinidad just off the coast of Venezuela). They are most often found in the leaf litter of wet forests, with nests located on the ground. Workers forage alone, apparently without recruiting nestmates or using pheromones. Within the tribe Stenammini, they seem to be most closely related to the genera Lordomyrma of Indo-Australia and Cyphoidris of Africa. [3]

Myrmicinae is a subfamily of ants, with about 140 extant genera; their distribution is cosmopolitan. The pupae lack cocoons. Some species retain a functional sting. The petioles of Myrmicinae consist of two nodes. The nests are permanent and in soil, rotting wood, under stones, or in trees.

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.

<i>Sphinctomyrmex</i> Genus of ants

Sphinctomyrmex is a genus of ants in the subfamily Dorylinae. The genus is a tropical and distinctive group, originally described by Mayr based on a single gyne collected in Brazil. Morphologically, the genus is characterized by the unique arrangement of the gastric segments, which are nearly equal in length and separated from each other by distinct constrictions. Very little is known on the natural history of Sphinctomyrmex. The few observations so far suggest that ants of this genus are nomadic predators of other ants. The genus Zasphinctus and approximately 20 species were formerly included, but were split out during revision of the Dorylinae genera by Borowiec (2016).

<i>Blepharidatta</i> Genus of ants

Blepharidatta is a rare Neotropical genus of ants in the subfamily Myrmicinae. The genus, formed by predatory species whose small colonies nest in soil or leaf-litter, has up to seven species, but most of them are waiting for a formal taxonomic treatment or confirmation.

<i>Tropidomyrmex</i> Genus of ants

Tropidomyrmex is a Neotropical genus of ants in the subfamily Myrmicinae. The genus contains the single species Tropidomyrmex elianae, known from Brazil.

<i>Stegomyrmex</i> Genus of ant

Stegomyrmex is a Neotropical genus of ants in the subfamily Myrmicinae. Strictly Neotropical in its distribution, the genus is known from Costa Rica to northern Argentina. It was once considered rare, but more recent sampling has revealed that the genus is relatively common in the leaf litter.

Sphinctomyrmex marcoyi is a Neotropical species of ants in the subfamily Dorylinae. It is the only Sphinctomyrmex species recorded in the Amazon Forest. Gynes and males are unknown.

<i>Sphinctomyrmex stali</i> Species of ant

Sphinctomyrmex stali is a Neotropical species of ants in the subfamily Dorylinae. Mayr described the genus Sphinctomyrmex with S. stali as its type species, based on a single dealate gyne. However, except for the holotype, there are no records of normal (alate) gynes for S. stali. All reproductive females collected after the original description are ergatoids.

Sphinctomyrmex schoerederi is a Neotropical species of ants in the subfamily Dorylinae. S. schoerederi is known only from the holotype, collected in a leaf litter sample from a forest remnant in the campus of Universidade Federal de Viçosa in Brazil, where it occurs in sympatry with S. stali. Gynes and males are unknown.

Kempfidris is a Neotropical genus of ants in the subfamily Myrmicinae containing the single species Kempfidris inusualis. Known from Brazil, Ecuador and Venezuela, the species was originally described as Monomorium inusuale in 2007, but was reclassified as the type species for the new genus Kempfidris in 2014. The species is only known from workers and almost nothing is known about their natural history.
