| Abstract | 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. |
