Ravavy is a Malagasy genus of ant in the subfamily Dolichoderinae containing the single species Ravavy miafina. [1]
The genus is only known from males from Madagascar. [2] The males are distinguished from all other described males in the dolichoderine genera by its unique mandibular shape. The elongate basal margin and reduced masticatory margin is considered apomorphic for the genus. The shape of the clypeus, length of scape and form of petiole, together form an inclusive diagnosis that isolates Ravavy from all other genera in the subfamily. No other described male is even superficially similar to Ravavy. The shape of the mandible in Bothriomyrmex , however, is reminiscent in some respects. The mandible in Bothriomyrmex is not triangular as in Tapinoma for example, but like Ravavy, has a short masticatory margin compared to the basal margin. In Bothriomyrmex, however, the masticatory margin includes at least three teeth, while in Ravavy a single tooth is present. [3]
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.
Dolichoderinae is a subfamily of ants, which includes species such as the Argentine ant, the erratic ant, the odorous house ant, and the cone ant. The subfamily presents a great diversity of species throughout the world, distributed in different biogeographic realms, from the Palearctic, Nearctic, Afrotropical region and Malaysia, to the Middle East, Australian, and Neotropical regions.
Paratrechina is one of seven ant genera in the Prenolepis genus-group from the subfamily Formicinae. Six species are included in Paratrechina; one of which, the longhorn crazy ant, is a widespread, pantropical pest.
Aptinoma mangabe is a species of ant in the subfamily Dolichoderinae. The species is known only from Antongil Bay, Madagascar.
Aptinoma antongil is a species of ant in the subfamily Dolichoderinae. The species is known only from Antongil Bay, Madagascar.
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.
Eutetramorium is a small genus of ants within the subfamily Myrmicinae. To date it contains three species found in Madagascar and Comoros.
Agroecomyrmecinae is a subfamily of ants containing two extant and two fossil genera. The subfamily was originally classified in 1930 by Carpenter as Agroecomyrmecini, a Myrmicinae tribe. Bolton raised the tribe to subfamily status in 2003, suggesting that Agroecomyrmecinae might be the sister taxon to Myrmicinae. It has since been discovered to be one of the earliest lineages of ants, a clade from the basal polytomy for all ants. In 2014, the subfamily was expanded to two tribes. The tribe Ankylomyrmini was moved from the subfamily Myrmicinae to Agroemyrmecinae.
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.
Tanipone is a Malagasy genus of ants in the subfamily Dorylinae.
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.
Boloponera is a genus of small ants in the subfamily Ponerinae. The genus contains the single species Boloponera vicans, known from a single worker specimen collected in leaf litter in the Central African Republic. It is sometimes referred to as Bry's ant after its discoverer, Brian Fisher.
Leptogenys is a genus of ants in the subfamily Ponerinae. Leptogenys is the most diverse ponerine ant genus in the world; it is widespread throughout tropical and subtropical regions and there are over 260 extant species described. Most species have ergatoid queens, and many have falcate, bowed mandibles and are specialists on isopod prey.
Promyopias is an Afrotropical genus of ant in the subfamily Ponerinae containing the single species Promyopias silvestrii. The rare genus has previously been regarded as a separate genus, as a subgenus and as a provisional synonymy, but was reinstated at genus-rank in 2008.
Aptinoma is a small genus of arboreal ants in the subfamily Dolichoderinae. Its two species are known only from Antongil Bay, Madagascar.
Malagidris is a Malagasy genus of ants in the subfamily Myrmicinae. Described in 2014, the genus contains six species.
Vitsika is a Malagasy genus of ants in the subfamily Myrmicinae. Described in 2014, the genus contains 14 species.
Royidris is a Malagasy genus of ants in the subfamily Myrmicinae. Described in 2014, the genus contains 15 species endemic to Madagascar.
Yantaromyrmex is an extinct genus of ants first described in 2013. Members of this genus are in the subfamily Dolichoderinae of the family Formicidae, known from Middle Eocene to Early Oligocene fossils found in Europe. The genus currently contains five described species, Y. constrictus, Y. geinitzi, Y. intermedius, Y. mayrianum and Y. samlandicus. The first specimens were collected in 1868 and studied by Austrian entomologist Gustav Mayr, who originally placed the fossils in other ant genera until the fossils were reviewed and subsequently placed into their own genus. These ants are small, measuring from 4 to 6 mm in length and can be characterized by their trapezoidal shaped head-capsules and oval compound eyes that are located slightly to the rear of the capsules midpoint, with no known ocelli present.
