Abstract
The barychelid genus Idiommata Ausserer, 1871 is reviewed: the type species Idiommata blackwalli O. Pickard-Cambridge, 1870 is diagnosed and variability of characters in males discussed. Idiommata is rediagnosed to include only I. blackwalli and I. scintillans (Rainbow & Pulleine, 1918), which lack intercheliceral peg setae. The female paralectotype of Idiommata scintillans is placed in Synothele Simon, 1908 and described as a new species, Synothele xintillans sp. nov., from South Australia. A new genus, Zidiommata gen. nov., is described for I. fusca L. Koch, 1874 (for which males are described), I. iridescens (Rainbow & Pulleine, 1918) and two new species, Z. simonmaraisi sp. nov. and Z. steveirwini sp. nov., all of which have intercheliceral pegs and are found in eastern Australia.
