Abstract:
Three populations of the pill millipede genus <i>Trachysphaera</i> Heller 1858 are present in Great Britain, one on the Isle of Wight, one in South Wales and one in mid-Wales. To identify and characterize the British <i>Trachysphaera</i> populations, the intraspecific and interspecific variation of the populations in South Wales and on the Isle of Wight were studied and evaluated in a first integrative study of members of <i>Trachysphaera</i>, utilizing barcoding and SEM. DNA was extracted from 28 British <i>Trachysphaera</i> and 10 French <i>T. lobata</i> (Ribaut 1954) specimens, one each of French T. cf. drescoi (Conde and Demange 1961) and <i>T. pyrenaica</i> (Ribaut 1908), and one of Spanish T. cf. rousseti (Demange 1959); the barcoding fragment of the COI gene was amplified and their genetic intra- and interpopulation distances compared with one another using two Italian <i>T.</i> spp. and one Croatian <i>T. schmidti</i> Heller 1858 specimens as near outgroups. To compare the genetic distances with the morphological characters, 15 characters of a total of 13 British <i>Trachysphaera</i>, together with two specimens of <i>T. pyrenaica</i>, two T. cf. drescoi and one of T. cf. rousseti were imaged, using the same individuals utilized for DNA extraction. Albeit both British populations are genetically distant, they are closely related (1.9–2.5% p-distance) to French <i>T. lobata</i>, corroborating results of earlier studies. Between different <i>Trachysphaera</i> species, genetic distance was high (16.7–18.8%). The morphological study showed the non-reliability of key taxonomic characters in <i>Trachysphaera</i>, with genetically identical individuals exhibiting morphological variation, especially on the telopods. The only observed morphological characters constant within and different between species were the number of rows of sclerotized bacilli on the tergites, as well as the shape of the male and female anal shield. Both, barcoding and the morphological study identify the British <i>Trachysphaera</i> populations as <i>T. lobata</i>.

Abstract:
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 &amp; 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.&#x0D;

Abstract:
The present catalogue completes (as the second of the two parts) data for the millipede collection of Czech arachnologist František Miller (1902–1983), housed in the National Museum in Prague. This second part of the catalogue brings information on a total of 341 specimens belonging to 34 millipede species; these specimens were previously housed at Charles University in Prague, and later moved to the National Museum. The material was collected during 1927–1950 in the territory of modern-day Czechia and Slovakia. Chelogona carpathicum, Polydesmus tatranus and Trachysphaera acutula are species of special importance for Slovak faunistics, due to their endemic occurrence. Glomeris klugii is the first record for Slovakia. For Leptoiulus noricus and Polydesmus inconstans, these are chronologically the oldest records from the territory of Slovakia.

Abstract:
As caves represent an extreme biotope with limited food sources, one might expect cave animal communities to exhibit low feeding specialization and to consume generally whatever organic matter is available. To test this hypothesis, we studied the feeding habits of several arthropod species in Slovakian and Romanian caves. A microanatomical approach utilizing histological methods was selected for this study. While saprophagous animals dominated, our study revealed variability within this nutritional group. Preferences ranged from fungal propagules (for the millipede Trachysphaera costata) to bacteria on bat guano (for the oribatid mite Pantelozetes cavaticus) and to cyanobacteria (for the microwhip scorpion Eukoenenia spelaea). The terrestrial isopod Mesoniscus graniger consumed a mixture of organic and inorganic substrates with plant material in various caves. These findings confirm an adaptability and phenoplasticity and, hence, a variability of characteristics developing under the pressure of extreme environmental factors.

Abstract:
A new genus and species of the pill millipede order Glomerida, Nearctomeris inexpectata n. sp., n. gen., is describedfrom the Eastern United States. The description of Nearctomeris brings the total number of American Glomerida generato three. In two of three known localitites, Nearctomeris co-occurs with species of the genus Onomeris Cook, 1896.Onomeris and Nearctomeris have almost an identical size (4–5.5 mm) and dark colour, but can be readily distingusihedby numerous non-sexual and sexual characters. Sexual characters of the male telopod also place Nearctomeris into thefamily Glomeridae, while the third American pill millipede genus Glomeroides Chamberlin, 1922 belongs to theProtoglomeridae. A key to all American genera of Glomerida is presented. For the first time in the order Glomerida, thepartial cytochrome c oxidase I mitochondrial gene was analyzed for the three American genera of the Glomerida,Glomeroides, Onomeris, and Nearctomeris together with European genera currently placed in different families,Glomeridella and Trachysphaera, as outgroups. Distance, maximum parsimony and maximum likelihood methods wereemployed. Maximum parsimony and likelihood analyses did not lead to a well-resolved phylogeny, but found a weaklysupported sister-group relationship between Nearctomeris and Onomeris. All five analyzed pill millipede genera differgreatly in their uncorrected basepairs (15–22%), and moderately in their amino acids (5–10%). As in Onomeris, the closestrelative of Nearctomeris can probably be found among the Asian genera Hyleoglomeris Verhoeff, 1910 or Hyperglomeris Silvestri, 1917. In America, more attention should be given to the search for other small-bodied, cryptic, rare Glomerida.

Abstract:
The Ojców National Park (southern Poland) is a small limestone area with outstanding natural values. Until now, there was a lack of information on the spatial distribution of species, their preference of biotopes and microhabitats in the area under study. An interesting question is also the occurrence of native species and the penetration of alien species. Biodiversity can be threatened in such a small, heavily visited by tourists and predominantly forested area, isolated from a similar landscape by agrocenoses and further eroded below the level of the surrounding landscape. Millipedes are soil arthropods, sensitive to calcified soils, stand structure, composition and availability of dead plant biomass, and microclimatic conditions. They are therefore an important reference group of animals for the management of the Ojców NP. In the spring of 2002 and autumn 2004, we carried out detailed inventory research of Diplopoda in the most typical habitats there. We recorded 19 taxa, 2 of which could not be determined to the species level. Together with literature data, a total of 23 species (ca 25% of Polish millipede fauna) are listed here. The occurrence of the moisture- preferring Carpathian mountain species Polydesmus tatranus Latzel, 1882 deserves attention. As important species, bound to preserved deciduous and mixed forests with plenty of dead wood, we consider Glomeris pustulata (Fabricius, 1781) and Nemasoma varicorne C. L. Koch, 1847. The retreat of rare native species as well as invasive aliene species were not recorded. The issue of the unclear nomenclature of the representatives of the genus Trachysphaera (Gervaisia) Heller, 1858 occurring in this area and accumulated throughout history is addressed.
