Monomorium

Bolton (1987) and Garcia, Wiesel and Fischer (2013) - Monomorium is a large and extremely diverse genus (~400 species) with about half of its constituent species occuring in the Afrotropical zoogeographical region. The vast majority of Monomorium species inhabit the Old World, particularly the tropics. Very few endemic species occur in North America (DuBois, 1986), and even fewer in the neotropical region where Monomorium is mostly replaced by an extensive Solenopsis fauna (Kempf, 1972). The main centres of speciation of Monomorium include Africa and Australia, with secondary centres in the Oriental region (Bingham, 1903) and Madagascar. Workers of Monomorium show a striking morphological diversity from group to group but within species-groups tend to be relatively uniform in structure. This genus contains some of the world's most widely distributed and successful tramp-species. Considering the wide distribution and species richness, it is not surprising that Monomorium are found in many terrestrial habitats and microhabitats. Astonishingly, very little is known of the natural history of most species (Ettershank, 1966). Feeding habits of most species seem to be generalistic, or more rarely granivorous. Several species are lestobiotic or parasitic and in addition, some species belong to the most successful and broadly distributed ant tramps (Ettershank, 1966; Bolton, 1987).
