Discovery edit
Two species of Gramastacus were originally described in 1972 by Edgar Riek from the Grampian region of western Victoria, Australia: Gramastacus insolitus and Gramastacus gracilis. In 1990, G. gracilis was determined to be a junior synonym of G. insolitus. In 2014, a new species Gramastacus lacus from the coastal regions of New South Wales was formally described by McCormack.[1]
Species edit
- Western Swamp Crayfish - Gramastacus insolitus Riek, 1972 (western Victoria, Australia) - a very small non-burrowing crayfish that shares burrows with larger crayfish species
- Eastern Swamp Crayfish - Gramastacus lacus McCormack, 2014 (coastal regions of New South Wales, Australia) - a larger, more robust crayfish species that digs their own burrows
