Synonymy of two monobasic Anurophorinae genera (Collembola: Isotomidae) from the Antarctic Continent

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. © 2015 The Entomological Society of New Zealand
