Strumigenys

Garcia, Wiesel and Fischer (2013) - A species-rich, worldwide occurring genus mainly distributed in the world tropics and subtropics (Bolton, 2000). The current genus definition includes the former genus Pyramica, which was proposed as junior synonym some years ago (Baroni Urbani, 2007). The taxonomy of the whole tribe was exhaustively revised by Bolton (2000) on a global scale. Most Strumigenys species are small, cryptic ants that nest and forage in leaf litter, in soil, or in rotten wood, whereas there are far fewer genus members that prefer an arboreal life-style. Many species are specialised predators possessing trap-jaw mandibles, and mainly hunt collembolans or other small arthropods (Hölldobler & Wilson, 1990; Bolton, 1999).
