“…We examined the phylogenetic affinities of C. amila and klovstadi by comparing it with other members of the Isotominae subfamily and refer to the morphological analyses presented in Stevens et al . () and Greenslade & Potapov (). This combined approach is critical in cases when phenotypes are shared because of convergence (homoplasy) rather than homology (see also Stevens et al .…”

“…More recently, Greenslade & Potapov () suggested it had a close relationship to a new aquatic species from the central highlands plateau in Tasmania, and transferred klovstadi to the new genus Chionobora , erected for the newly described Tasmanian species C. amila Greenslade & Potapov, . Based on twelve morphological characters, they suggested that klovstadi was more related to Chionobora than it was to Desoria (Table 1 and Fig.…”

An endemic springtail from northern Victoria Land, Antarctica, was recently moved from Desoria to the new genus Chionobora, erected for a new species C. amila from lakes in the central highland plateau of Tasmania. This new combination for klovstadi was based on characters similar to both species (although not definitive) and an apparent preference for aquatic habitats. Here we show that neither of these inferences are valid. We sampled from two lake localities to obtain C. amila, and in doing so, we describe its habitat as riparian, not aquatic. We compared specimens of C. amila with klovstadi within a phylogeny using three genes (mtDNA COI, 18S rDNA, D1‐D5 of 28S rDNA) for 59 Isotominae terminals. We show that klovstadi is not closely related to the genus Chionobora that has closest affinities to the genus Isotomurus. As previously identified, klovstadi has no close affinities to any existing genus in Isotominae. Based on additional ecological, morphological and molecular evidence, we erect a new genus for klovstadi, Kaylathalia gen. n.

“…Further study based on a larger taxonomic sampling and additional genes less prone to signal saturation than COI will be necessary to understand the relations between I. festus sp. nov., the members of the 'antennalis' group and morphologically similar taxa such as the two 'austral' forms, Chionobora Greenslade & Potapov, 2015 (Tasmania) and Kaylathalia Stevens & d'Haese, 2016 (Antarctic), which share several essential characters with the 'antennalis' group of Isotomurus (Greenslade & Potapov, 2015, Stevens & d'Haese, 2016 and make the situation even more complex.…”

Colour pattern is the most common character to identify species in several large genera of Collembola. Its use often raises problems due to various and poorly investigated extent of chromatic variability among species. Isotomurus festus sp. nov. is here described from Kunashir Isl. (the Kuriles, the Far East of Russia). The species, a member of the 'antennalis' group, is characterized by the lack of trichobothria and slender claws, but is greatly variable in coloration. DNA barcoding (COI) results supports that all the colour forms encountered belong to the same species. While colour pattern has been shown to be the most reliable character for species identification in several Entomobryidae genera, it might not be the case in Isotomurus Börner, 1903, the sole large Isotomidae genus where colour pattern is routinely used for taxonomy.

“…The Antarctic continental collembolan fauna islands in the Gerlache Strait consisted of 12 species in 11 genera in 1995 (Greenslade 1995). With this paper and new genus (Greenslade & Potapov 2015) the generic diversity is reduced to 10. As collecting intensity increases in the region, as it has in recent years, and DNA sequence data is accumulated, the number of species is likely to rise and at least one has already been foreshadowed (M. I.…”

Two monotypic endemic genera, Gressittacantha and Neocryptopygus, from Continental Antarctica, and erected on a single character respectively, are here synonymised with Cryptopygus, a genus with two already described species on the Antarctic Continent. A table of diagnostic characters for the now four Cryptopygus species from the Antarctic Continent is provided and comments made on habitats and Antarctic collembolan diversity. A possible new species of Cryptopygus from the Antarctic Continent is foreshadowed.
