Abstract
The Australian endemic open-holed trapdoor spider genus Proshermacha Simon, 1908 currently contains 13 described species distributed throughout southern Australia. We describe three new species from the Southwest Australia biodiversity hotspot: Proshermacha katana sp. nov. and Proshermacha rapier sp. nov. from the Esperance Plains bioregion, and Proshermacha scimitar sp. nov. from the Esperance Plains and Jarrah Forest bioregions. We further conduct a multilocus molecular analysis to reveal the phylogenetic placement of two of these newly-described species.
