Adetomyrma is a genus of ants endemic to Madagascar. Workers of this genus are blind. The type species Adetomyrma venatrix was described in 1994, with the genus being an atypical member of its tribe, the Amblyoponini. This tribe includes the Dracula ants, members of which can feed on the hemolymph of larvae and pupae.
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.
Pheidole bula is a species of ant in the genus Pheidole. It was discovered in Fiji, and described by E. M. Sarnat in 2008.
Pheidole simplispinosa is a species of ant native to the forests of Fiji.
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.
Vicinopone is a monotypic Afrotropical genus of arboreal ants in the subfamily Dorylinae. Vicinopone conciliatrix, the only species in the genus, was first described as Simopone conciliatrix by Brown in 1975 and was transferred to its own genus by Bolton & Fisher in 2012. V. conciliatrix appears to be quite widely distributed but rare. Its rarity is more likely apparent than real because it nests and forages in trees, rarely if ever coming down to the ground.
Lordomyrma is a genus of ants in the subfamily Myrmicinae.
Tyrannomyrmex is a rare tropical genus of ants in the subfamily Myrmicinae. Three similar species, only known from workers, are recognized and share small eyes and edentate mandibles.
Daceton boltoni is a Neotropical species of arboreal ants in the subfamily Myrmicinae. The species occurs in Peru and Brazil and is similar to its sister species, D. armigerum.
Pheidole ragnax is a species of ant in the subfamily Myrmicinae.
Pheidole teneriffana is a species of ant in the subfamily Myrmicinae.
Lordomyrma reticulata is a species of ant in the subfamily Myrmicinae.
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.
Meranoplus cryptomys is a Malagasy species of ant in the genus Meranoplus.
Meranoplus mayri is a Malagasy species of ant in the genus Meranoplus.
Pristomyrmex tsujii is a species of ant in the genus Pristomyrmex. Known from Fiji, where they are widely distributed but rarely encountered. The species has a discrete ergatoid queen caste that is intermediate between a worker and an alate queen.
Proceratium vinaka is a species of ant from Fiji, and the third species of its genus to be identified there.
Tetramorium smaug is a species of myrmicine ant native to Ambatovy, Amber Mountain National Park, and Ivohibe in Madagascar. It was found in montane rainforests around elevations of 900–1,300 metres (3,000–4,300 ft). It is believed to live in vegetation as opposed to on the forest floor. Coloration is dark brown or black. The head and mesosoma have rough surfaces while the gaster is smooth. The head has a large number of hairs, but the amount of hair decreases on each segment posteriorly. The species has long propodeal spines with a broad base. It was named after the dragon Smaug from J. R. R. Tolkien's novel The Hobbit.
