Two decades have passed since the publishing of the last checklist of the millipedes of Slovakia. During this time, several new faunistic records have been added and taxonomic revisions have occurred. The present updated checklist summarises data on all millipede species recorded in Slovakia, including altogether 93 species.
For each species, general habitat characteristics, ecological classification and distributional pattern are provided. Ecological classification is presented for the first time for the millipede species occurring in Slovakia and is proposed as a tool for ecological studies and for the nature protection purposes. Special remarks are given to the species newly found for Slovakia, Geoglomeris subterranea Verhoeff, 1908, Brachyiulus lusitanus Verhoeff, 1898, Cylindroiulus britannicus (Verhoeff, 1891), C. parisiorum (Brölemann & Verhoeff, 1896) and Polydesmus burzenlandicus Verhoeff, 1925, as well as to C. arborum Verhoeff, 1928, the species newly confirmed for Slovakia after more than 70 years.
