Technomyrmex is a formicid ant genus containing more than 97 extant species, almost all of which are native to the Old World tropics: 29 species in the afro-tropical region, 45 species in the Oriental and Malesian regions, 25 in the Malgasy and Austral regions.Two species are currently known natives to the New World: T. fulvus, from Colombia, Costa Rica, and Panama; and T. gorgona, from Colombia.Two other species, T. difficilis and T. vitiensis, occur as exotics in the New World. Ants in this genus are mostly tree-nesting, and the very few that build ground nests forage extensively in the tree canopy.They feed mainly on homopteran honeydew, and supplement this by hunting arthropods and arthropod eggs (Bolton 2007).
This genus, in particular the Albipes group (about 40+ species), contains some of the world’s most accomplished tramp, invasive and pest species. Some can form enormous colonies spanning multiple nests and containing millions of adult ants.Albipes ants all show a technique of colony reproduction that is unique in the Formicidae, which involves production of “reproductive worker-queen intercast” individuals, which allow nests to multiply by fission. Colonies cover large areas, populating diverse ecosystems and negatively impact pollinators, pollination and seed dispersal, and other ant species (Bolton 2007).
Technomyrmex difficilis, for example, is a “tramp ant” that has spread, possibly originally from Madagascar, through many parts of the old world tropics along with humans.In 1986 this ant was first reported in the New World in 1986 in Miami-Dade County, Florida.Since then it has spread not only across many other Florida counties, but also across the Southern US and all the way to Seattle, Washington (where it was found in the Seattle Zoo), as well as in five west Indies countries: Puerto Rico, St. Thomas, St. Croix, Nevis, and Antigua (Wetterer 2008).It is considered an important pest in Florida (Warner et al. 2010), and Wetterer (2008) predicts: “It is probable that over the next few years T. difficilis will become increasingly important as a pest in Florida and the West Indies.”
The other exotic in the New World, T. vitiensis, is a tramp ant widespread across Southeast Asia, on the continent and islands from the Indian Ocean to Polynesia, and in some European greenhouses (Bolton 2007; Fernández & Guerrero 2008; Wetterer 2008).The first New World report was in the Golden Gate Park Conservatory, San Francisco, California (Bolton 2007).It has since been collected in two remote inland forest sites in French Guyana, though it is not clear how it got there.This species (as has T. difficilis) has been frequently misidentified as T. albipes in museum collections and in the literature (Wetterer 2008).

I [introduced species]
Allied to Tapinoma and distinguished by the peculiar structure of the gizzard, the calyx of which is covered with small clear spots apparently representing thin areas in the chitin. The anus is terminal in the worker and female. The former is small and monomorphic, the latter but little larger. The anterior wings have two closed cubital cells and a discoidal cell.
The male has a short antennal scape, not longer than the two first joints of the funiculus. Wings like those of the female, but with the cubital vein more or less interrupted near the second cubital cell. In one species, T. albipes , both apterous and winged males are known to occur.
The genus is confined to the Old World tropics, ranging over the Ethiopian, Indomalayan, Papuan, and Australian Regions (Map 33). Some of the species nest in the ground, others make small carton nests on the bark of trees. T. albipes is being rapidly disseminated in the tropics by commerce and sometimes occurs in hothouses in temperate regions.
This genus is represented by a single introduced species in the T. albipes complex, which occasionally establishes residence in hothouses (e.g., in Golden Gate Park, San Francisco). The group is under taxonomic revision by Barry Bolton (pers. comm.). References: Deyrup(1991), Ogata et al. (1996), Smith (1965), Tsuji et al. (1991), Yamauchi et al. (1991).
Technomyrmex is a genus of ants in the subfamily Dolichoderinae. With 98 species, it is one of the largest and most diverse ant genera in the Dolichoderinae.[2] The genus distributed throughout the tropical and subtropical zones with most species occurring in the Oriental-Malesian and Afrotropical regions.[3] One species, Technomyrmex albipes is a tramp ant now widespread throughout the tropics due to human activities.[4]

Technomyrmex (лат. , от др.-греч. τεχνο- +μύρμηξ «умелый муравей») — род муравьёв подсемейства долиходерины (Dolichoderinae, Tapinomini). Встречаются повсеместно: Африка, Евразия, Америка, Австралия, Океания. Около 100 видов[2][3][4][5][6].
Мелкие земляные муравьи, в основном коричневато-чёрного цвета. Усики самок и рабочих 12-члениковые (у самцов антенны состоят из 13 сегментов). Жвалы рабочих многозубчатые, с 9—25 зубцами. Нижнечелюстные щупики, как правило, 6-члениковые, нижнегубные щупики состоят из 4 сегментов (формула 6,4). У некоторых видов формула 5,3 (Technomyrmex pratensis и Technomyrmex lasiops) или 4,3 (Technomyrmex lujae и Technomyrmex reductus). Голени средних и задних ног с одной апикальной шпорой. Проподеум без зубцов. Стебелёк между грудкой и брюшком состоит из одного небольшого сегмента (петиоль низкий, редуцировнный, без чешуйки или узелка). Жало отсутствует[7].
Известно несколько ископаемых видов из миоцена и олигоцена:
