The first known troglomorphic, eyeless spider wasp (Hymenoptera: Pompilidae): <scp> <i>Troglopompilus miracaecatus</i> </scp> gen. et sp. nov. from the Nullarbor Caves, Western Australia

Abstract Surveys of caves of the Nullarbor Plain, Western Australia, revealed a remarkable assemblage of exceptionally well‐preserved mummified arthropods, comprising Araneae, Blattodea, Coleoptera and Chilopoda, all of which exhibit high levels of troglomorphism, lacking eyes and showing a number of other adaptations. Of note, this arthropod assemblage also included a pompilid wasp which is eyeless and brachypterous and unlike any member of the family known globally. Here, we describe this amazing wasp as Troglopompilus miracaecatus gen. et sp. nov. , and discuss its remarkable morphology and possible affinities and biology.
