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 Lithobius melanops, L. microps, Geophilus carpophagus, G. flavus, Strigamia transsilvanica and Stenotaenia linearis, a probably introduced species. Of the 27 published Estonian millipede species, the data on two species proved erroneous, and two new species were recorded (Craspedosoma raulinsii and Cylindroiulus britannicus). Two previously recorded millipede species – Brachyiulus pusillus and Mastigophorophyllon saxonicum – 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.

The research of Estonian Myriapoda has been quite unsystematic and sporadic. Very little has been published in English thus much of the information may be currently unavailable to the wider myriapodological community (e.g.,
An unpublished collection of myriapods from 1937, preserved currently in the entomological collection of Estonian University of Life Sciences, Tartu (
We owe thanks for much of what is known about Estonian Myriapoda to the works of the Estonian entomologist Juhan Vilbaste (1924–1985). His “Keys to Estonian Millipedes” lists 21 species as proven to occur in Estonia at that time (
As complete as possible, bibliography of historical records of myriapods in Estonia was compiled, reviewing all the available faunistic studies and other records. The main Estonian zoological collections were searched for myriapod material (Estonian Museum of Natural History, Tallinn; Tartu University Museum of Natural history and the private insect collection of Allan Selin, Maardu). Some collections abroad known to house Estonian material were contacted for further information (Finnish Museum of Natural History and Zoologische Staatssammlung München, Germany).
New material was collected using: (1) pitfall traps, (2) Tullgren funnel and Kempson apparatus, (3) sifting moss, leaf litter and detritus with a standard entomological sieve, (4) manual searching in suitable habitats and daytime retreats, and (5) as by-catch of non-target species with window pane traps (attached to tree trunks) and Malaise traps (for particular description of the trapping projects, see
The material was collected from 276 localities covering all parts of Estonia (see Table
1. Coastal meadows and alvars;
2. Broad-leaved (nemoral) forests (dominated by Quercus robur, Tilia cordata, Acer platanoides and herbs in the understory);
3. Boreo-nemoral deciduous forests (dominated by Alnus incana or Salix species);
4. Dry heathland forests (dominated by Pinus sylvestris, with Cladonia sp. or Calluna vulgaris in understory);
5. Drier boreo-nemoral mixed forests (dominated by Pinus sylvestris with Sorbus and Acer and Vaccinium myrtillus in understory);
6. Mesophilic boreal forests (dominated by Picea abies, Oxalis acetosella in understory);
7. Hillock forests (dominated by Corylus avellana, herbs in the understory);
8. Carrs and paludifying forests (dominated by Picea abies, Betula pendula and Pinus sylvestris);
9. Bogs;
10. Fens and waterlogged meadows;
11. Inland mesophilic grasslands;
12. Rural gardens;
13. Urban parks and graveyards;
14. Arable fields.
The barplot diagrams were produced by dividing the number of findings in a habitat type by the proportion of sampling effort in that particular habitat (i.e. the number of “sampling events” consisting of one trapping period or one hand collecting trip with subsequent Tullgren extraction of soil and litter samples) (Figure
All available material consisting of 1656 centipede, 4095 millipede, 29 symphylan, and six pauropod specimens were identified or re-identified and databased. The following list contains all the known published records of Estonian myriapods, followed by numbers of studied specimens and collecting localities. Full details for one finding from each locality are given in “Supplementary information”. Only publications with original data are listed, subsequent ones citing these (e.g.,

The current study adds six centipede and two millipede new country records, while two millipedes, viz. Polydesmus coriaceus and Ophyiulus pilosus are presently removed from the Estonian checklist. All the Symphylan and Pauropod species represent new records. It is unclear whether the new records are due to insufficient previous data (which may well be true for centipedes, except Stenotaenia linearis) or range shifts. The human or climate driven range shifts up to over hundred km northwards in recent decades have been also detected elsewhere (
The range of Craspedosoma raulinsii seems to expand north and eastwards. It was apparently first collected in Latvia between 2003 and 2008 (
Four species, viz. Strongylosoma stigmatosum, Cylindroiulus punctatus, Archiboreiulus pallidus and Choneiulus palmatus, occurring in neighbouring Latvia and/or Finland might be found also in Estonia, but more studies, especially in southern Estonia are needed. The species Mastigophorophyllon saxonicum, previously reported from many localities in southern Estonia was not re-found, and appears to have become more rare or extinct (which is also the case in Latvia,
The currently known fauna of Estonian Diplopoda and Chilopoda is quite similar to the neighbouring regions. 79% of the species are shared with Finland and 87.5 % are shared with Latvia. The similarity to Latvian fauna may be in fact even higher, as several species occurring both in Estonia and Lithuania might be present also in Latvia. Estonian Symphyla and Pauropoda deserve further attention. At present, they remain too poorly known to allow for any comparisons.
