Australian native species formerly classified in the genus Trogoderma Dejean are revised, and following recent changes in Megatomini classification by Zhou et al. (2022), are confirmed as members of the Gondwanan genus Eurhopalus Solier. Of the fifty-two previously described native species, eight species are considered junior synonyms, five species known from female sex only are treated as uncertain and one is treated as incertae sedis. All recognised species are described, thoroughly illustrated and keyed. The identification key, mostly based on male characters is also provided. Twenty-five new species are described: Eurhopalus albicomus Szitó, Ślipiński and Zhou sp. nov. (WA); E. brookfield Ślipiński and Zhou sp. nov. (SA); E. broome Ślipiński & Zhou sp. nov. (WA); E. canberra Ślipiński and Zhou sp. nov. (ACT); E. carrabin_Szitó, Ślipiński and Zhou sp. nov. (WA); E. crinitus Ślipiński and Zhou sp. nov. (QLD); E. csiro Ślipiński and Zhou sp. nov. (ACT); E. decimus Ślipiński & Zhou sp. nov. (SA); Eurhopalus enderby Ślipiński and Zhou sp. nov. (WA); E. eneabba Ślipiński and Zhou sp. nov. (WA); E. harrisonae Ślipiński and Zhou sp. nov. (TAS); E. hedland Ślipiński & Zhou sp. nov. (WA); E. koy Ślipiński and Zhou sp. nov. (QLD); E. marloo Ślipiński and Zhou sp. nov. (WA); E. mixtus Szitó, Ślipiński and Zhou sp. nov. (WA); E. monteithi Ślipiński & Zhou sp. nov. (Lord Howe Island); E. muralag Ślipiński and Zhou sp. nov. (QLD); E. obsoletus Ślipiński and Zhou sp. nov. (TAS); E. profusus Ślipiński and Zhou sp. nov. (TAS); E. psacus Ślipiński and Zhou sp. nov. (SA); E. reidi Ślipiński and Zhou sp. nov. (NSW); E. setiger Szitó, Ślipiński and Zhou sp. nov. (WA); E. taeniatus Szitó, Ślipiński and Zhou sp. nov. (WA); E. thornorum Ślipiński and Zhou sp. nov. (WA); E. trophis Ślipiński & Zhou sp. nov. (WA.). The following new species synonymies are proposed: Psacus mastersii Macleay, 1872 = Megatoma apicalis Macleay, 1871; Trogoderma longius Blackburn, 1903 = Trogoderma singulare Blackburn, 1891;Trogoderma maurulum Blackburn, 1903 = Megatoma morio Erichson, 1842; Trogoderma tasmanica Armstrong, 1942 = Megatoma tenuefasciata Reitter, 1881b; Trogoderma debilius Blackburn, 1903 and Trogoderma adelaidea Blackburn, 1891 = Trogoderma eyrense Blackburn, 1891; Trogoderma ellipticum Armstrong, 1942 = Trogoderma antipodum Blackburn, 1891; Trogoderma inconspicuum Armstrong, 1942 = Trogoderma lindense Blackburn, 1891.Lectotypes are designated for: Megatoma apicalis Macleay, 1871; Megatoma morio Erichson, 1842; Psacus attagenoides Pascoe, 1866; Psacus callubriensis Armstrong, 1945; Psacus mastersii Macleay, 1872; Trogoderma Adelaidea Blackburn, 1891; Trogoderma alpicola Blackburn, 1891; Trogoderma antipodum Blackburn, 1891; Trogoderma apicipenne Reitter, 1881; Trogoderma baldiense Blackburn, 1891; Trogoderma blackburni Lea, 1908; Trogoderma boganense Armstrong, 1942; Trogoderma consors Arrow, 1915; Trogoderma debilius Blackburn, 1903; Trogoderma explanaticolle Armstrong, 1942; Trogoderma exsul Blackburn, 1903; Trogoderma eyrense Blackburn, 1891; Trogoderma frater Arrow, 1915; Trogoderma froggatti Blackburn, 1892; Trogoderma inconspicuum Armstrong, 1942; Trogoderma leai Armstrong, 1942; Trogoderma lindense Blackburn, 1891; Trogoderma longius Blackburn, 1903; Trogoderma macleayi Blackburn, 1891; Trogoderma maurulum Blackburn, 1903; Trogoderma meyricki Blackburn, 1891 Trogoderma nigrobrunneum Armstrong, 1942; Trogoderma nigronitidum Armstrong, 1845; Trogoderma parvum Armstrong, 1942; Trogoderma picinum Armstrong, 1945; Trogoderma reitteri Blackburn, 1892; Trogoderma rufipenne Armstrong, 1942; Trogoderma silvicolum Armstrong, 1949; Trogoderma varipes Blackburn, 1892; Trogoderma yorkense Blackburn, 1891. The interception records and available specimens of pestiferous Trogoderma species from Australia have also been reviewed and based on extensive sampling and interception records we believe that only Trogoderma variabile Ballion has been established in Australia. Both T. inclusum (LeConte) and T. glabrum (Herbst) have been intercepted in Australia but apparently failed to establish viable populations and should be treated as absent from Australia.
