Stigmatomma electrinum is an extinct species of ant in the genus Stigmatomma . It was described in 2009 after fossils were found in the Baltic Amber. [1]
Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from vespoid wasp ancestors in the Cretaceous period. More than 13,800 of an estimated total of 22,000 species have been classified. They are easily identified by their geniculate (elbowed) antennae and the distinctive node-like structure that forms their slender waists.
Nothomyrmecia, also known as the dinosaur ant or dawn ant, is an extremely rare genus of ants consisting of a single species, Nothomyrmecia macrops. These ants live in South Australia, nesting in old-growth mallee woodland and Eucalyptus woodland. The full distribution of Nothomyrmecia has never been assessed, and it is unknown how widespread the species truly is; its potential range may be wider if it does favour old-growth mallee woodland. Possible threats to its survival include habitat destruction and climate change. Nothomyrmecia is most active when it is cold because workers encounter fewer competitors and predators such as Camponotus and Iridomyrmex, and it also increases hunting success. Thus, the increase of temperature may prevent them from foraging and very few areas would be suitable for the ant to live in. As a result, the IUCN lists the ant as Critically Endangered.
Amblyopone is a genus of 10 species of ants, found in Australia, New Caledonia, New Guinea and New Zealand. Ants of this genus possess the gamergate, meaning workers are able to reproduce within a colony lacking a queen.
Ant-Man is a 2015 American superhero film based on the Marvel Comics characters of the same name: Scott Lang and Hank Pym. Produced by Marvel Studios and distributed by Walt Disney Studios Motion Pictures, it is the 12th film in the Marvel Cinematic Universe (MCU). The film was directed by Peyton Reed from a screenplay by the writing teams of Edgar Wright and Joe Cornish, and Adam McKay and Paul Rudd. It stars Rudd as Scott Lang / Ant-Man alongside Evangeline Lilly, Corey Stoll, Bobby Cannavale, Michael Peña, Tip "T.I." Harris, Anthony Mackie, Wood Harris, Judy Greer, Abby Ryder Fortson, David Dastmalchian, and Michael Douglas as Hank Pym. In the film, Lang must help defend Pym's Ant-Man shrinking technology and plot a heist with worldwide ramifications.
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.
Amblyoponinae is a subfamily of ants in the poneromorph subfamilies group containing 13 extant genera and one extinct genus. The ants in this subfamily are mostly specialized subterranean predators. Adult workers pierce the integument of their larvae and pupa to imbibe haemolymph, earning them the common name Dracula ant.
Stigmatomma is a genus of ants in the subfamily Amblyoponinae. The genus has a worldwide distribution, and like most other amblyoponines, Stigmatomma species are specialized predators. First described by Roger (1859), it was for a long time considered to be a synonym of Amblyopone until it was revived as an independent genus by Yoshimura & Fisher (2012) based on worker mandible morphology.
Mystrium is a rare genus of ants in the subfamily Amblyoponinae. First described by Roger (1862) with the description of the queen of M. mysticum, the genus contains 14 species, all of which occur in the rainforests of the Old World with over half of the species endemic to the Malagasy region.
Xymmer is a genus of ant in the subfamily Amblyoponinae containing the single species Xymmer muticus.
Stigmatomma pluto is a species of ant in the subfamily Amblyoponinae. The species was first described as Amblyopone pluto by Gotwald and Levieux in 1972 and moved to the genus Stigmatomma in 2012.
Fulakora is a genus of ants in the subfamily Amblyoponinae. The genus has a worldwide distribution, and like most other amblyoponines, Fulakora species are specialized predators. It was originally described as, and for a long time considered to be, a subgenus of Stigmatomma until it was elevated to an independent genus by Ward & Fisher (2016).
Stigmatomma scrobiceps is a species of ant in the genus Stigmatomma. It was described as Bannapone scrobiceps by Guénard et al. in 2013, based on two specimens collected in Yunnan Province, China, and placed as the second species in Bannapone. It was moved to Stigmatomma by Ward & Fisher (2016).
Stigmatomma groehni is an extinct species of ant in the genus Stigmatomma. It was described by Dlussky in 2009, where it was found in the Baltic Amber, alongside another extinct species Stigmatomma electrinum.
Stigmatomma testaceum, is a species of ant in the subfamily Amblyoponinae. The type locality is Sri Lanka.
Ant-Man and the Wasp: Quantumania is a 2023 American superhero film based on Marvel Comics featuring the characters Scott Lang / Ant-Man and Hope Pym / Wasp. Produced by Marvel Studios and distributed by Walt Disney Studios Motion Pictures, it is the sequel to Ant-Man (2015) and Ant-Man and the Wasp (2018) and the 31st film in the Marvel Cinematic Universe (MCU). It was directed by Peyton Reed, written by Jeff Loveness, and stars Paul Rudd as Scott Lang and Evangeline Lilly as Hope van Dyne, alongside Jonathan Majors, Kathryn Newton, David Dastmalchian, Katy O'Brian, William Jackson Harper, Bill Murray, Michelle Pfeiffer, Corey Stoll, and Michael Douglas. In the film, Lang, Van Dyne, and their family are accidentally transported to the Quantum Realm and face off against Kang the Conqueror (Majors).
Stigmatomma pallipes, or vampire ant, is a species of ant in the subfamily Amblyoponinae. It is one of three species of Stigmatomma native to North America. They can be hard to find due to their habitat and small colony size.
Stigmatomma trigonignathum is a species of ant in the subfamily Amblyoponinae. It is considered one of the rarest ants in the world, only known from one specimen collected in 1948 and another observed in 2008. Both records are from the Piedmont region of North Carolina.
