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. [1]
Sphinctomyrmex marcoyi is known only from the holotype, a worker collected from a soil sample. Nothing is known about its biology. [1] S. marcoyi can be easily separated from other species in the genus by its comparatively diminutive size, conspicuously elongate head, comparatively short scapes, and by the presence of a smooth longitudinal stripe on the dorsum of mesosoma, which is otherwise covered by foveolae and subdecumbent to erect hairs. [1]
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.
Dorymyrmex is a genus of ants in the subfamily Dolichoderinae.
Leptomyrmex, or spider ants, is a genus of ants and a distinctive member of the ant subfamily Dolichoderinae. Commonly known as "spider ants" for their long legs and spider-like movements, these orange and black ants are prominent residents of intact wet forest and sclerophyll habitats throughout their range. One extant species, Leptomyrmex relictus, is known from central Brazil; otherwise, the global distribution of this genus is restricted to eastern Australia, New Caledonia and New Guinea, as well as the nearby Indonesian islands of Aru and Seram.
Megalomyrmex is a genus of ant in the subfamily Myrmicinae. The genus is known only from the Neotropics, where some of the species are specialized parasites or predators of Attini.
Oxyepoecus is a Neotropical genus of ant in the subfamily Myrmicinae. The genus is a member of the tribe Solenopsidini and currently includes 20 species.
Diaphoromyrma is a genus of ants in the subfamily Myrmicinae. It contains the single species Diaphoromyrma sofiae, known only from workers from the type locality in Bahia, Brazil. The genus is apparently close to Allomerus and Diplomorium in the Solenopsidini, but its tribal attribution remains uncertain.
Leptanilloides is a genus of ants in the subfamily Dorylinae. Leptanilloides is an uncommonly collected genus with subterranean habits in the New World Andean and sub-Andean tropics.
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).
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.
Lachnomyrmex is a Neotropical genus of ants in the subfamily Myrmicinae. The genus consists of 16 species restricted to the Neotropics, known from southern Mexico to northern Argentina. 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.
Tropidomyrmex is a Neotropical genus of ants in the subfamily Myrmicinae. The genus contains the single species Tropidomyrmex elianae, known from Brazil.
Lenomyrmex is a Neotropical genus of ant in the subfamily Myrmicinae.
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 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.
Dorymyrmex amazonicus is a Neotropical species of ant in the subfamily Dolichoderinae.
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.
Megalomyrmex acauna is a Neotropical species of ants in the subfamily Myrmicinae. Known from Brasil and Peru. It is similar to M. leoninus-group. Its head width (HW) is 1.45—1.63 mm and head length (HL) is 1.68—1.75 mm. Its scapus length (SL) is 2.13—2.28 mm.
