Two new species of the open-holed trapdoor spider genus Proshermacha (Araneae: Mygalomorphae: Anamidae) from southern Western Australia

Abstract
The open-holed trapdoor spider genus Proshermacha Simon, 1908 is endemic to southern Australia, and currently contains 11 named species. We describe two new species from south-western Australia: Proshermacha telaporta sp. nov. from the Geraldton Sandplains and Swan Coastal Plain bioregions, and Proshermacha robertblosfeldsi sp. nov. from the Warren bioregion.
