''Dinoponera quadriceps'' is a queenless species of ants in the subfamily Ponerinae. The species, known from Brazil, is similar to ''Dinoponera mutica'' and uses venom for subduing large live prey and defense. Its venom could be of use to the pharmaceutical industry. ==Distribution== ''Dinoponera quadriceps'' is found in the Caatingas, Cerrados, upland humid forest and Atlantic forest in the northeastern Brazilian states of Alagoas, Bahia, Ceará, Paraiba, Pernambuco and Rio Grande do Norte.〔 Of all ''Dinoponera'', ''Dinoponera quadriceps'' has the largest colonies with an average of 80 workers (range 26–238).〔 ''Dinoponera quadriceps'' usually nest at the base of trees. Observations of ''Dinoponera quadriceps'' nests show that in more arid Caatinga and Cerrado habitats, nests are predominantly constructed under trees, whereas in Atlantic forest 60% of nests were 3 m away from any tree. Nests are deeper in ''Dinoponera quadriceps'' (and ''Dinoponera australis'') than in ''Dinoponera gigantea'', Monnin ''et al''. (2003) suggests that deeper nests are a possible adaptation to seasons and aridity.〔
