New species of millipedes occurring in the Czech Republic: species discovered in the period 2003–2017

Since the year 2003, six millipede species new for the Czech Republic were announced. All of them were discovered in small populations mostly in natural habitats. They can be divided into two groups. One is represented by rare, relict and stenoecic species (Hungarosoma bokori, Hylebainosoma tatranum and Melogona transsylvanica). The other group is represented by species exhibiting a closer relationship to subterranean habitats in the Czech Republic (Brachychaeteuma bradeae, Macrosternodesmus palicola and Geoglomeris subterranea); their presence in the Czech Republic was revealed by modified pitfall traps used for collecting of deep-living invertebrates and by combination of several methods used during the research in caves. All six species are listed in the Red List of Threatened Invertebrates in the Czech Republic.
