An annotated catalogue of the millipede order Julida (Diplopoda) in Bulgaria

The paper presents the first catalogue of the millipede order Julida (Diplopoda: Helminthomorpha) in Bulgaria. The order is currently known to comprise 3 families (Blaniulidae, Nemasomatidae and Julidae), 21 valid genera, 51 species and 3 subspecies in the country. Another 11 species and the genus Thachypodoiulus were quoted probably erroneously for Bulgaria. Archiboreoiulus pallidus and Megaphyllum dentatum were reported without mention of their exact localities, and have never been found since. All relevant literature sources are given for each species group taxon with exact pages; detailed distribution by geographical regions; as well as a list of habitats where the species was found in the country; altitudinal range; chorotype; and sometimes additional remarks. New data, among which the second and third finds in the country of Megaphyllum anatolicum denticulatum and Brachyiulus bagnalli, respectively, are given for 19 species. The paper also provides brief analysis about the habitat preferences and zoogeographical affinities of Bulgarian julids
