Abstract
Conservation management in ancient landscapes has shifted in recent years from the protection of single species to the broader management of areas of high biodiversity. One of the landscapes that has most benefited from this shift is the south-west of Western Australia, an internationally recognised biodiversity hotspot and one of the oldest and most stable landscapes on Earth. Significant progress has been made in recent years to identify refugia in the south-west and prioritise them for invertebrate protection but more studies are still needed to assist practical conservation management. Here, we describe a new genus of pseudoscorpions from south-western Australia (Pseudoscorpiones: Pseudotyrannochthoniidae: Karrichthonius gen. nov. ) that has speciated extensively within mesic refugia. Karrichthonius is endemic to the High Rainfall Province of the biodiversity hotspot and features often-localised populations in spatially isolated mesic habitats. Through a combination of DNA barcoding, morphological features and spatial mapping, we infer 12 species: Karrichthonius giganteus (Beier, 1971) comb. nov. , K. booraraensis , sp. nov. , K. buzattoi , sp. nov. , K. dalei , sp. nov. , K. farquhari , sp. nov. , K. heatherae , sp. nov. , K. leniae , sp. nov. , K. porongurupensis , sp. nov. , K. pyungurupensis , sp. nov ., K. rixi , sp. nov. , K. talyuberlupensis , sp. nov. and K. toolbrunupensis , sp. nov . All species are short-range endemics and occur in landforms that are either known refugia for invertebrate conservation or inferred here as potential refugia to be recognised and analysed further. By mapping species distributions and providing species diagnoses, we contribute to an understanding of invertebrate biodiversity in the south-west, and strengthen the concepts that are underlying conservation management practices in biodiversity hotspots.

期刊介绍：
Invertebrate Systematics (formerly known as Invertebrate Taxonomy) is an international journal publishing original and significant contributions on the systematics, phylogeny and biogeography of all invertebrate taxa. Articles in the journal provide comprehensive treatments of clearly defined taxonomic groups, often emphasising their biodiversity patterns and/or biological aspects. The journal also includes contributions on the systematics of selected species that are of particular conservation, economic, medical or veterinary importance.
Invertebrate Systematics is a vital resource globally for scientists, students, conservation biologists, environmental consultants and government policy advisors who are interested in terrestrial, freshwater and marine systems.
Invertebrate Systematics is published with the endorsement of the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Australian Academy of Science.
