Open-holed trapdoor spiders of the genus Teyl (Mygalomorphae: Nemesiidae: Anamini) from Western Australia's Pilbara bioregion: a new species and expanded phylogenetic assessment

The open-holed trapdoor spiders of the genus Teyl Main, 1975 from the Pilbara bioregion of Western Australia are investigated. A single endemic species from the southern Pilbara, T. heuretes sp. nov., is newly described, representing the northern-most occurrence of the genus in Australia. Legacy molecular data for Australian Nemesiidae, along with newly generated sequences for all described species of Teyl known from Western Australia, are analysed using Maximum Likelihood methods, providing molecular data for T. heuretes and an expanded phylogenetic assessment of the genus.
