New species described are: Aphanesia greyi, Astibicola bicolor, Cheilo liparetroides, Dikellites abditus, Parasciton inermis, Paronyx setifera, Scitaloides malanda, Stenochelyne noctis.

The following species, previously described, are transferred to other genera: Aneucomides hirticollis Blackburn to Xyridea, Haplonycha ruficollis Lea to Ictigaster, Engyops castaneus Lea, Haplonycha minuta Lea and Platydesmus flavipennis Macleay to Neso, Pachygastra victoriae Blackburn to Hadropechys, Telura suturalis Lea and Telura clypealis Lea to Teluroides, Platydesmus castaneus Lea, Platydesmus inamoenus Blackburn, Platydesmus inusitatus Blackburn, Platydesmus major Blackburn, Platydesmus obscuricornis (Blanchard), Platydesmus punctulaticeps Blackburn, Frenchella hirsuta Frey and Frenchella sparsiceps Blackburn to Colobostoma.
