A synopsis of Estonian myriapod fauna (Myriapoda: Chilopoda, Diplopoda, Symphyla and Pauropoda).

The data on Estonian Myriapoda are scattered in various publications and there has been no overview of the fauna up to the present. A critical summary of the previous information on Estonian Myriapoda is given, supplemented by new records and distribution maps. Altogether, 5784 specimens from 276 collecting sites were studied. To the hitherto recorded 14 centipede species are added Lithobiusmelanops , L.microps , Geophiluscarpophagus , G.flavus , Strigamiatranssilvanica and Stenotaenialinearis , a probably introduced species. Of the 27 published Estonian millipede species, the data on two species proved erroneous, and two new species were recorded ( Craspedosomaraulinsii and Cylindroiulusbritannicus ). Two previously recorded millipede species - Brachyiuluspusillus and Mastigophorophyllonsaxonicum - were not found in the recent samples, the latter may have become more rare or extinct. Pauropoda and Symphyla lack previous reliable records. Combined with published data, the number of myriapod species known from Estonia is now set at 52. Some changes in species distribution and frequencies were detected comparing the published data with new records. Some data about habitat preferences of the more common species are also given. The majority of species have a western Palaearctic distribution, while six species are at the northern limit of their ranges.
