A new dwarf schendylid centipede (Chilopoda: Geophilomorpha: Schendylidae) with a low number of legs from Serbia, Balkan Peninsula.

Schendyla antici sp. nov., a dwarf geophilomorph from the Mt. Medvednik (Western Serbia, Balkan Peninsula), is described and illustrated based on the specimens extracted from the soil samples. A detailed comparison with all species within the genus is provided. The new species has the lowest number of leg-bearing segments within the genus Schendyla Bergse & Meinert, 1866, and one of the lowest in the order Geophilomorpha in general.

Dazbogosoma mokoshae, a new cavernicolous species of the previously monospecific genus Dazbogosoma Makarov amp; uri, 2012, from Serbia (Diplopoda: Chordeumatida: Anthroleucosomatidae).

A new troglobiotic species, Dazbogosoma mokoshae sp. nov., is described from a cave in the eastern Serbia. This is the second species from the previously monospecific genus Dazbogosoma Makarov uri, 2012. An updated diagnosis of the genus, as well as a diagnosis, detailed description, illustrations and in situ photographs of a new species, based on both males and females, are presented. The distribution and relationships within the Bulgarosoma complex comprising D. mokoshae sp. nov. are briefly discussed.

Review of Trachysphaera Heller, 1858 (Diplopoda: Glomerida: Glomeridae) in Serbia, with taxonomic notes on the genus.

The glomerid genus Trachysphaera Heller, 1858 in Serbia is revised, based on recently collected specimens and historical material. Six species are presently recorded from Serbia, viz., Trachysphaera corcyraea (Verhoeff, 1900), T. cristangula (Attems, 1943), T. schmidtii Heller, 1858, and T. similicostata (Radu Ceuca, 1951), all new to the fauna of the country, as well as T. costata (Waga, 1857a) and T. lobotarsus (Attems, 1943). All of these species are richly illustrated and mapped. To verify the identity of some species, historical material from the Natural History Museum in Vienna, including syntypes, is also studied, and two lectotypes have been designated. Some misidentifications from the literature have been corrected. Trachysphaera acutula (Latzel, 1884) syn. n., T. cultrifera (Verhoeff, 1906) syn. n. and T. multiclavigera (Verhoeff, 1898) syn. n. are all considered as junior subjective synonyms of T. schmidtii. Trachysphaera attemsi Golovatch, 1976 syn. n. is transferred from the list of synonyms of T. costata to the list of synonyms of T. corcyraea. One species, T. similicostata, is resurrected from synonymy. Relationships between some congeners and the taxonomic problems within the genus are briefly discussed.
