Abstract
A remarkable new species in the ant genus Daceton, which has remained monotypic for 205 years, is described from Brazil and Peru. The new species, Daceton boltoni sp. nov., is similar to its sister species, D. armigerum, but differs from it mainly in the form of the pronotal lateral spines and in the pilosity of the first gastral segment. The taxonomic history and biology of the genus is reviewed.References
