Riodinidae is the family of metalmark butterflies. The common name "metalmarks" refers to the small, metallic-looking spots commonly found on their wings. The 1,532 species are placed in 146 genera. Although mostly Neotropical in distribution, the family is also represented both in the Nearctic, Palearctic, Australasian (Dicallaneura), Afrotropic, and Indomalayan realms.
Sphaeroceridae are a family of true flies in the order Diptera, often called small dung flies, lesser dung flies or lesser corpse flies due to their saprophagous habits. They belong to the typical fly suborder Brachycera as can be seen by their short antennae, and more precisely they are members of the section Schizophora. There are over 1,300 species and about 125 genera accepted as valid today, but new taxa are still being described.
Heroini is a fish tribe from the Cichlasomatinae subfamily in the family Cichlidae (cichlids). All cichlids native to the Greater Antilles, United States, Mexico and northern Central America are members of this tribe. It also includes most cichlid species in southern Central America and several species from South America. A large percentage of its species were formerly placed in the genus Cichlasoma but have since been moved to other genera.
A gamergate is a mated worker ant that can reproduce sexually, i.e., lay fertilized eggs that will develop as females. In the vast majority of ant species, workers are sterile and gamergates are restricted to taxa where the workers have a functional sperm reservoir ('spermatheca'). In some species, gamergates reproduce in addition to winged queens, while in other species the queen caste has been completely replaced by gamergates. In gamergate species, all workers in a colony have similar reproductive potentials, but as a result of physical interactions, a dominance hierarchy is formed and only one or a few top-ranking workers can mate and produce eggs. Subsequently, however, aggression is no longer needed as gamergates secrete chemical signals that inform the other workers of their reproductive status in the colony.
Dinoponera is a strictly South American genus of ant in the subfamily Ponerinae, commonly called tocandiras or giant Amazonian ants. These ants are generally less well known than Paraponera clavata, the bullet ant, yet Dinoponera females may surpass 3–4 cm (1.2–1.6 in) in total body length, making them among the largest ants in the world.
Ectatomminae is a subfamily of ants in the poneromorph subfamilies group 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. Heteroponinae used to be its own subfamily, but was merged into Ectatomminae in 2022.
Ectatomma is a Neotropical genus of ants in the subfamily Ectatomminae. The genus contains 17 described extant species and one extinct species.
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).
Belonopelta is a Neotropical genus of ants in the subfamily Ponerinae. The genus contains two species: B. deletrix is known from Mesoamerica and Colombia, while B. attenuata is only known from Colombia. Members of this genus are rarely collected, and little is known about their habits. Males remain unknown for both species, and queens and larvae have only been described for B. deletrix.
Poneracantha triangularis is a Neotropical species of ant in the subfamily Ectatomminae. Native to the forests of South and Central America, P. triangularis is a predatory ant that feeds on millipedes. In its native range, this species is known from Buenos Aires, Argentina in the south to Costa Rica in the north, with records from eight countries in South America, and two countries of Central America. The first records of P. triangularis outside its native range came from Florida beginning in 1985 and Alabama in 1996.
Holcoponera is a genus of ants in the subfamily Ectatomminae. They are found in the Neotropics, Southeast Asia, and Oceania. The genus was synonymized under Gnamptogenys for a long time, however Camacho et al. 2022 reinstated the validity of this genus.
Ectatomma tuberculatum, known in Qʼeqchiʼ as the kelep, is a Neotropical species of ant in the subfamily Ectatomminae. Common in the Neotropics, the species is found from Mexico to Argentina. It is a host to the related social parasite Ectatomma parasiticum, the only known parasitic species in the subfamily Ectatomminae.
Pseudectatomma is an extinct genus of ants in the formicid subfamily Ectatomminae described by from fossils found in Europe. The genus contains two species dating from the Eocene, Pseudectatomma eocenica and Pseudectatomma striatula.
Gnamptogenys ericae is a species of ant in the subfamily Ectatomminae.
Poneracantha is a genus of ants in the subfamily Ectatomminae. They are found in Central America, the Caribbean, and Central America. One species, Poneracantha triangularis, is invasive to the southeastern United States. The genus was synonymized under Gnamptogenys for a long time, however Camacho et al. 2022 reinstated the validity of this genus.
Stictoponera is a genus of ants in the subfamily Ectatomminae. They are found in Southeast Asia and Oceania. The genus was synonymized under Gnamptogenys for a long time, however Camacho et al. 2022 reinstated the validity of this genus.
Alfaria is a genus of ants in the subfamily Ectatomminae. They are found in Mexico, Central America, and South America. The genus was synonymized under Gnamptogenys for a long time, however Camacho et al. 2022 reinstated the validity of this genus.
