“…In order to translate these groupings into taxonomic descriptions, adoption of an abbreviated or faster taxonomy is required (Riedel et al, 2013). In recent studies (Murphy et al, 2015b;King et al, 2022), robust examples of a total evidence approach to species description from genetic lineages, especially in situations of cryptic species complexes, have been provided. Recommendations in such studies have included: standard generic descriptions to establish a strong taxonomic framework; use of integrative approaches (combining DNA, morphological characters, and locality data) to describe species; and Open Access publication practices for efficient dissemination.…”

The Great Artesian Basin of Australia represents one of the largest and deepest basins of freshwater on Earth. Thousands of springs fed by the Basin are scattered across Australia’s arid zone, often representing the sole sources of freshwater for thousands of kilometers. As “islands” in the desert, the springs support endemic fauna and flora that have undergone millions of years of evolution in almost total isolation. Here, we review the current body of knowledge surrounding Great Artesian Basin springs and their significance from ecological, evolutionary, and cultural perspectives using South Australian spring wetlands as a case study. We begin by identifying the status of these springs as critical sources of groundwater, the unique biodiversity they support, and their cultural significance to the Arabana people as Traditional Custodians of the land. We then summarize known threats to the springs and their biota, both exogenous and endogenous, and the potential impacts of such processes. Finally, considering the status of these at-risk habitats as time capsules of biodiversity, we discuss lessons that can be learnt from current conservation and management practices in South Australia. We propose key recommendations for improved biodiversity assessment and monitoring of Great Artesian Basin springs nationwide, including 1) enhanced legal protections for spring biota; 2) increased taxonomic funding and capacity; 3) improved biodiversity monitoring methods, and 4) opportunities for reciprocal knowledge-sharing with Aboriginal peoples when conducting biodiversity research.

“…In this bioregion, potential impacts from mining developments can have major implications for subterranean fauna and their conservation, including loss of biodiversity and ecosystem services such as water purification and nutrient cycling (Boulton et al, 2008;Griebler & Avramov, 2015;Korbel & Hose, 2011;McRae et al, 2015;Saccò et al, 2022;Tang et al, 2008;Venarsky et al, 2022). Despite the ongoing efforts of taxonomic specialists over the last decade to describe the many taxa collected in the region (Giachino et al, 2021;Harvey et al, 2023;Karanovic, 2007;Karanovic, 2006;King et al, 2022;Perina et al, 2018Perina et al, , 2019aSmith et al, 2012;Stringer et al, 2022;Tang et al, 2008), the full extent of the diversity and species distributions of most subterranean fauna in the Pilbara is still poorly known. Challenging factors to species descriptions in these groups include conservative morphology due to convergent evolution (Culver & Pipan, 2009;Juan et al, 2010), difficulties in sampling the underground environment, and quality and quantity of the material collected (Halse, 2018a, b).…”

The Pilbara bioregion (Western Australia) has become a hotspot for subterranean fauna as a consequence of many surveys conducted to comply with Western Australian environmental regulation requirements. In this bioregion, mining developments can have major implications for subterranean fauna and their conservation. However the diversity and species distributions of most taxa are still poorly known, including the crustacean family Parabathynellidae. Recent studies on a widespread genus of this family (Atopobathynella) from the Pilbara highlighted several undescribed taxa with interesting patterns of distribution. In the Gudai Darri locality, the northern flank of the Hamersley Range occurs as a stepped escarpment intersected by dykes and gullies, with groundwater occurring within fractured rocks abutting the Fortescue River valley, where a separate regional aquifer occurs. This investigation aimed to observe whether stygofauna species distributions (1) reflected the separation between the two major aquifers within the Hamersley Range and the Fortescue Valley; and (2) were influenced by the presence of dykes. We examined the Atopobathynella species occurring in the study area using morphological and molecular data. The results reflected the hydrogeological complexity of the study area with six new lineages of Atopobathynella, recorded mainly in different gullies, that do not share a most recent common ancestor. Two species are described here A. pagetae sp. nov. and A. lythei sp. nov., and four additional species are delineated through preliminary morphological analyses and molecular data. This study will improve future environmental impact assessments and the understanding of Parabathynellidae taxa distribution in hydrogeological complex areas.

AimThere has been growing interest in non‐cave subterranean habitats and their influence on the evolution of troglomorphic (i.e. ‘subterranean adapted’) species. Studies on the diversification of aquatic subterranean organisms in these habitats generally support the ‘subterranean island’ hypothesis, whereby isolated subterranean refuges lead to patterns of short‐range endemism. However, their terrestrial counterparts have received less attention. We aimed to elucidate the applicability of the ‘subterranean island’ hypothesis to terrestrial subterranean fauna through genetic analyses of two widespread troglomorphic cockroach species. To investigate the influence of subterranean biogeography, we also analysed a closely related species that inhabits ‘classic’ cave environments to represent a contrasting biogeographic comparison.LocationPilbara region, Western Australia, and the Chillagoe‐Mungana Caves, Queensland (Australia).TaxaCave cockroach species: Nocticola cockingi, Nocticola quartermainei and Nocticola australiensis.MethodsWe used DArTseq to generate genome‐wide SNPs in 78 samples, and Sanger sequencing to generate 16S mtDNA data. We then applied various population genomic analyses to characterize the distribution of genetic diversity within the three study species.ResultsWe identified distinct genetic clusters within the two Pilbara species; however, there appeared to be a notable lack of discernible population differentiation across large parts of their range (>135 km), opposing the subterranean island hypothesis. The highest level of population differentiation in the three study species was between the two caves in Queensland, ~3 km apart.Main ConclusionsThe Pilbara subterranean habitat appeared to be conducive to gene flow across relatively large distances, contrasting high levels of endemism observed in other subterranean taxa within the region. The disparate patterns of gene flow among the Pilbara and Queensland study species emphasize the significance of differing subterranean habitats on patterns of dispersal and vicariance. These inferences will inform conservation genetic management of these species, and may help elucidate the evolutionary paradox of widespread subterranean fauna.
