- Description: A taxonomic revision of the genus Subisotoma Stach, 1947 is presented. Subisotoma pusilla (Schaffer, 1900), S. tenuis (Dunger, 1982), and S. asiatica (Martynova, 1970) are re-described based on type and fresh material. Eight new species of the genus are described; S. pomorskii sp. nov., S. homonomica sp. nov., S. bisensillata sp. nov., S. guzeriplica sp. nov., S. posteriomollis sp. nov., S. multisensillata sp. nov., S. cruda sp. nov., and S. erratica sp. nov., using material from Eurasia. A key to the known species of Subisotoma is given. A new genus, Isotopenola gen. nov., is erected for some southern representatives of the 'Cryptopygus' complex related to Subisotoma: I. australis (Womersley, 1934) comb. nov., I. loftyensis (Womersley, 1934) comb. nov., I. nilgiris (Denis, 1947) comb. nov. They are re-described based on type and fresh material. A new species I. delicata sp. nov. is described from Australia. A key to the known species of Isotopenola is given.

- Description: A new species and genus, Skadisotoma inpericulosa, is described from south-eastern Australia. It possesses some characters that are found in Tomoceridae, such as a long cylindrical dens that is medially bent and a mucro with at least six teeth of different sizes and three setae but in other characters it resembles an isotomid. In this it shows similarities to the Boreal genus Mucronia Fjellberg, but differs from it in the possession of spines on the dens and in some chaetotaxic characters.
