This species was transferred from the Trochanteriidae into the Family Trachycosmidae as stated in the following paper, published in January 2022: Azevedo GHF, Bougie T, Carboni M, Hedin M and Ramirez MJ "Combining genomic, phenotypic and Sanger sequencing data to elucidate the phylogeny of the two-clawed spiders (Dionycha)" Molecular Phylogeny and Evolution 166 1-14.

Although this species belongs to the same family as the flattened Morebilus and Rebilus species it has a much taller profile than they do. The markings on the upper surfaces of its abdomen and the shape of the fovea on its carapace are distinctive features.

Known Range: Found in near-coastal bush settings from about Sydney to Melbourne.

Spider(s) with a very similar appearance: Trachycosmus sculptilis.
