Abstract Aleochara blackburni Bernhauer & Scheerpeltz (Aleocharinae) is a little‐known coastal rove beetle, not studied since specimen was collected from coasts in Port Lincoln, South Australia, 1888. We report the discovery of additional specimens, which were at sites distributed between central‐east and south‐east Tasmania, Australia. Habitus photographs, redescription, host records illustrations diagnostic characters are provided. To investigate phylogenetic placement A. taxonomic problems within Emplenota Triochara clade, we 34 populations 13 one inland species generated molecular phylogeny genus Gravenhorst based on three partial mitochondrial genes ( COI , tRNA leucine COII ). Our results showed that sister group bilineata clade + curtula suggested curtidens Klimaszewski (Vancouver, Canada) trisulcata Weise (Chiba, Japan) used previous study misidentifications fucicola Sharp zerchei (Assing), respectively. Five independent origins specialisation to habitat (clades A–E) hypothesised, has independently colonised Southern Australian coast (clade E).
