Continental risk assessment for understudied taxa post-catastrophic wildfire indicates severe impacts on the Australian bee fauna.

The 2019-2020 Australian Black Summer wildfires demonstrated that single events can have widespread and catastrophic impacts on biodiversity, causing a sudden and marked reduction in population size for many species. In such circumstances, there is a need for conservation managers to respond rapidly to implement priority remedial management actions for the most-affected species to help prevent extinctions. To date, priority responses have been biased towards high-profile taxa with substantial information bases.

Molecular diversity and species delimitation in the family Gasteruptiidae (Hymenoptera: Evanioidea).

Gasteruptiidae Ashmead is an easily recognised family of wasps with ∼589 described species worldwide. Although well characterised by traditional taxonomy, multiple authors have commented on the extreme morphological uniformity of the group, making species-level identification difficult. This problem is enhanced by the lack of molecular data and molecular phylogenetic research for the group.

Systematics of the parasitoid wasp genus Aulacus Jurine (Hymenoptera: Evanioidea: Aulacidae) from Australia.

The Aulacidae is a small family of Hymenoptera that are parasitic on wood-boring beetles and wasps. They have a worldwide distribution but are generally poorly studied, particularly for the southern hemisphere. This study is part of a series that aims to describe the Australian fauna which is relatively species-rich compared with other regions.

First record of Gasteruption Latreille (Hymenoptera: Evanioidea: Gasteruptiidae) from Fiji with the description of a new species.

A new Gasteruption Latreille species, G. tomanivi, is described from Viti Levu, Fiji. The new species is the first record of the genus for Fiji and can be distinguished from other Oceanian Gasteruption species by the length of the mesosoma and the large malar space compared with the length of the pedicel.

A new species of the endemic Australian genus Hyptiogaster Kieffer Hymenoptera: Gasteruptiidae).

Hyptiogaster arafura sp. nov. is described from Arafura Swamp, Northern Territory, Australia, as the eleventh species of Hyptiogaster Kieffer (Hymenoptera: Gasteruptiidae).

The gasteruptiid wasp fauna of New Caledonia, with description of three new species of Gasteruption (Hymenoptera: Evanioidea: Gasteruptiidae).

The rarely collected gasteruptiid wasp fauna (Evanioidea: Gasteruptiidae) of New Caledonia is reviewed. Previously only two species of Pseudofoenus (Hyptiogastrinae) were known. Here, we record the subfamily Gasteruptiinae from New Caledonia for the first time and describe three new species of Gasteruption: G.
