Hadreule Thomson, 1859 is a small genus of ciid beetles, comprising three Holarctic and one Australasian species. Here, three additional species from the Southern Hemisphere are described: H. mineira sp. nov. from Southeast and Northeast Brazil, characterised by the eight‐segmented antennae and male with large abdominal sex patch; H. vivianae sp. nov. from Southeast Brazil, characterised by the elytra darker than pronotum and male with small abdominal sex patch; and H. pacifica sp. nov. from Polynesian and Micronesian islands, characterised by the third antennomere being twice as long as the fourth and the possession of a two‐segmented antennal club. A brief description and images of the presumed larva of H. pacifica sp. nov. are also provided, together with images of the presumed larva of H. mineira sp. nov. and an identification key for adults of the world species of Hadreule.
