While conducting a survey of freshwater fungi in the temperate region of southern Australia, we came across two previously undiscovered anamorphic Ascomycota, a phoma-like coelomycete and a dictyochaeta-like hyphomycete. The coelomycetous fungus was classified in the family Morosphaeriaceae (Pleosporales) as a new genus, primarily supported by molecular data. We hereby introduce Minivolcanus unicellularis, the new genus and species, accompanied by both morphological and molecular evidence. Additionally, the dictyochaeta-like hyphomycete was placed in the genus Achrochaeta in the Chaetosphaeriaceae (Chaetosphaeriales) based on a combination of morphological characteristics and phylogenetic analyses utilising ITS, 28S, and TEF1 sequences. This newly identified species is proposed as Achrochaeta rivulata, the second species described within this genus. These findings expand our knowledge of fungal diversity in the region.

Reflecting the state of invertebrate taxonomy globally, many bee taxa in Australia are in need of revision, and this includes the most species-rich endemic subfamily, the Euryglossinae. In addition to undescribed species, many euryglossine species have been described from only a single sex. Over 30 taxonomic papers on euryglossines have been published, however the majority of these were by a single author, and before the advent of molecular technologies that can be used to efficiently and reliably associate the sexes of these often sexually-dimorphic species. Additionally, the reproductive behaviours of most bee species are unknown, and published observations of reproductive activities are few and far between. Based on DNA barcoding we associate the male of Xanthesma (Xenohesma) perpulchra (Cockerell, 1916) (Hymenoptera: Colletidae), with the female of Xanthesma (Xanthesma) brachycera (Cockerell, 1914). We propose that Xanthesma perpulchra syn. nov. is a junior synonym of X. brachycera, and, due to the enlarged male eyes, that X. brachycera should be placed in subgenus Xenohesma. Consistent with other X. (Xenohesma), we report swarming behaviour for this species observed in bushland remnants within an urbanised biodiversity hotspot, which can be related to the male’s enlarged eyes. Our research has indicated the value of DNA barcoding, and raises further questions regarding the taxonomy of this diverse endemic Australian subfamily.

Two new species in the orb-weaving spider genus Nanometa Simon, 1908 are described, N. ilanejzykowiczi sp. nov. and N. cerastes sp. nov. (family Tetragnathidae Menge, 1866), elevating the number of described Australian species to eight. Both new species have so far only been recorded from Hartz Mountains National Park, southern Tasmania, at about 1,200 metres a.s.l., where two other species, N. tasmaniensis Álvarez-Padilla, Kallal & Hormiga, 2020 and N. tetracaena Álvarez-Padilla, Kallal & Hormiga, 2020 also occur.

This work describes a new and distinctive species of hoverfly, Xylota norma sp. nov., discovered in Malaise trap samples collected from the Tarkine rainforests of northwest Tasmania during the austral summer of 2021-22. To date, the species is only known from the type series of six specimens. It is only the second species in its genus known from Australia – the other species, Xylota flavitarsis, is widespread along the eastern seaboard of Australia and throughout Tasmania.

We describe five new species of mouse spiders, genus Missulena Walckenaer, 1805 (family Actinopodidae Simon, 1892), from national parks and / or conservation reserves in Western Australia, based on somatic and genitalic characteristics, and molecular data where these were available: Missulena durokoppin sp. nov., M. gelasinos sp. nov., M. ignea sp. nov., M. minima sp. nov., and M. terra sp. nov. Three of these species, M. ignea sp. nov., M. durokoppin sp. nov., and M. minima sp. nov have very limited known distributions, being known only from a single park or reserve.
