Munnogonium George & Strömberg, 1968

As rediagnosed by Just & Wilson (2007) Munnogonium is known from the eastern Pacific north of San Diego, the south-western Atlantic, Magellan Strait southern Chile, and now Australia. The three eastern Pacific species, Munnogonium tillerae (Menzies & Barnard, 1959), M. erratum (Schultz, 1964), and M. waldronense George & Strömberg, 1968, were poorly defined but surveys of the literature and specimens allow us to provide a better key.
