Three new species of Pacidesmus are described from caves in southern China: P. whitteni, new species, from Guangxi Zhuang Autonomous Region, P. trilobatus, new species, and P. uncatus, new species, the latter two from Yunnan Province. The three new species differ from the most similar congeners mainly in certain details of gonopodal structure. Additional records of P. bifidus, P. martensi and P. sinensis are also presented. The genus is thus composed of a single high-montane forest-dwelling species in northern Thailand at present, as well as another 11 species, all presumed troglobionts from southern China.

Abstract: Two new species of the millipede genus Spirobolellus are described: S. kurtschevae sp.n. from Lou Island, Admiralty Islands, Papua New Guinea, and S. tschernovi sp.n. from Norfolk Island, New South Wales, Australia. Because the telopodite of the anterior gonopods on the caudal face is swollen and directed not laterad, but mesad, S. tschernovi sp.n. seems to share this peculiar feature only with S. antipodarum (? = S. reischeki). This also allows us to confirm that Desmocricellus Attems, 1953 is a junior subjective synonym of Spirobolellus Pocock, 1894.

РЕЗЮМЕ. Описаны два новых вида диплопод рода Spirobolellus: S. kurtschevae sp.n. с острова Лоу (острова Адмиралтейства, Папуа-Новая Гвинея) и S. tschernovi sp.n. с острова Норфолк (Новый Южный Уэллс, Австралия). Вид Spirobolellus tschernovi sp.n. столь необычен, что, кажется, его вздутый сзади и направленный внутрь, а не вбок телоподит передних гоноподов есть еще только у S. antipodarum (? = S. reischeki). Это одновременно позволяет подтвердить, что Desmocricellus Attems, 1953 \— младший субъективный синоним Spirobolellus Pocock, 1894.

Abstract: Arisemolus kurtschevae sp.n. is described as the first species of the genus to be reported from mainland (and inland) Papua New Guinea. The new species differs from all three other accepted congeners that range from the Mariana and Caroline islands in Micronesia, through the Bismarck Archipelago and Vanuatu in Melanesia, to western New Guinea, Indonesia, primarily by certain details of gonopodal structure, in particular the considerably longer/higher sternite of the anterior gonopods and the shape of the distal part of the posterior gonopods. New illustrations are provided for both A. tamicus (Attems, 1914) (the type species) and A. ralumensis obscuratus (Attems, 1914), the latter being formally synonymized with A. ralumensis ralumensis, syn.n.

A new species of glomeridellid millipede is described from Guizhou Province, southern China: Tonkinomeris huzhengkuni sp. nov. This new epigean species differs very clearly in many structural details, being sufficiently distinct morphologically and disjunct geographically from T. napoensis Nguyen, Sierwald \& Marek, 2019, the type and sole species of Tonkinomeris Nguyen, Sierwald \& Marek, 2019, which was described recently from northern Vietnam. The genus Tonkinomeris is formally relegated from Glomeridae and assigned to the family Glomeridellidae, which has hitherto been considered strictly Euro-Mediterranean in distribution and is thus new to the diplopod faunas of China and Indochina. Tonkinomeris is re-diagnosed and shown to have perhaps the basalmost position in the family Glomeridellidae. Its relationships are discussed, both morphological and zoogeographical, within and outside the Glomeridellidae, which can now be considered as relict and basically Oriental in origin. Because of the still highly limited array of DNA-barcoding sequences of the COI mitochondrial gene available in the GenBank, the first molecular phylogenetic analysis of Glomerida attempted here shows our phylogram to be too deficient to consider meaningful.

Two new species of Plusioglyphiulus are described from southern Cambodia. Plusioglyphiulus biserratus sp. nov. is clearly distinguished from all congeners by the shape of the telopodites of the posterior gonopods which are distinctly serrate laterally and by the anterior gonopods showing only a pair of single, smooth and curved coxosternal processes. Plusioglyphiulus khmer sp. nov. is distinguished by having most crests on the collum being complete and male legs 1 showing long, prominent, one-segmented telopodites, coupled with the oblong-subtrapeziform, membranous, posterior gonopods with a small bifid process at about a third of the telopodite length. Notes on the variation of Plusioglyphiulus boutini Mauri\ès, 1970 are also given, including a colour photograph of fresh, live material.

A molecular phylogeny based on COI sequences is used to study the relationship within and among the genera Polyxenus and Propolyxenus from Western Europe to the southern Caucasus.

The generic classification of the Palaearctic tribe Leptoiulini is revised, with 11 genera being recognized. The main differences between the genera, all presented in a tabular form, lie in the structure of the 2nd and 7th leg-pairs of the male, coupled with gonopodal conformations: the presence/absence and the degree of development of flagella on the promeres, and of the phylacum and velum on the opisthomeres. Based on abundant new material, only three genera and seven species of Leptoiulini, all keyed, mapped and properly illustrated, are shown to occur in the Caucasus: Chatoleptophyllum flexum Golovatch, 1979, Kubaniulus gracilis Lohmander, 1936, K. lativelatus sp. nov., Leptoiulus hastatus Lohmander, 1932 (= L. disparatus Lohmander, 1936, syn. n.), L. tanymorphus (Attems, 1901), L. meskhii sp. nov., and L. gonopodialis sp. nov. All species are endemic or subendemic to the region, while Kubaniulus Lohmander, 1936 represents the only genus in the tribe which is restricted to the Caucasus, in particular, the western and central parts of the Caucasus Major. The distributions are mainly allopatric, but a few pairs of species are para- or even sympatric.

Based on all available information, 339 species from 71 genera, 26 families, and eleven orders of Diplopoda have hitherto been recorded from mainland China, the fauna thus being very rich, albeit far from completely known, comprising various zoogeographic elements and populating very different environments. Diplopods mainly occur in various woodlands, in caves, and high in the mountains. Most species (\> 90 \%, usually highly localised, including 160 cavernicoles), 18 genera, and one family are strictly endemic to continental China. Mapping not only the horizontal, but also the vertical distributions of Diplopoda in China shows the bulk of the fauna to be expectedly restricted to forested lowland and mountain biomes or their remnants. Yet some Chordeumatida, Callipodida, Polydesmida, Julida, and even Spirobolida seem to occur only in the subalpine to alpine environments and thus may provisionally be considered as truly high-montane. The long-acknowledged notions of China being a great biogeographic zone transitional between the Palaearctic and Oriental regions generally find good support in millipede distributions, in particular at the higher taxonomic levels (generic, familial, and ordinal). While the Palaearctic/Holarctic components expectedly dominate the fauna of the northern parts of the country, the Oriental ones prevail in its south and along the Pacific coast. Both realms are increasingly mixed and intermingled towards China\’s centre. However, in addition to the above traditional views, based on distribution patterns alone, southern China seems to harbour a rather small, but highly peculiar faunal nucleus or origin centre of its own, whence Himalaya, Myanmar, Thailand, Indochina and/or Taiwan could have become populated by younger lineages. The millipede fauna of continental China is thus a tangled mixture of zoogeographic elements of various origins and ages, both relict and more advanced. The few anthropochores must have been the latest faunal \“layer\” to populate China.

The diplopod fauna of Georgia, Transcaucasia, is very rich given the country\’s relatively small territory; it presently comprises 103 species from 44 genera, 12 families, and 7 orders. Most of the Diplopoda known from Georgia (86 species, or 83\%) demonstrate Caucasian distribution patterns, 36 and 46 species, as well as 8 and 9 genera being endemic or subendemic to the country, respectively. A single Holarctic family, Anthroleucosomatidae (order Chordeumatida), contains 44 Caucasian species and 20 genera, of which 27 species and 14 genera are endemic or subendemic to Georgia. Likewise, all species from the orders Polyzoniida, Siphonocryptida, Glomerida and Chordeumatida, as well as most species of Julida and Polydesmida are native, also endemic or subendemic to the Caucasus, but the genera and families they represent are widely distributed at least across the Euro-Mediterranean Realm. Most of the presumed troglobionts in the Caucasus appear to be confined to western Georgia\’s karst caves (14 species, 5 genera). Within Georgia, the fauna of the western part (= Colchis) is particularly rich and diverse, while that of the central and eastern parts of the country grows increasingly depauperate inland following the gradual climatic aridisation from west (Black Sea coast) to east (Armenia and Azerbaijan). The vertical distribution of the Diplopoda in Georgia, as well as the Caucasus generally, shows the bulk of the fauna restricted to forested lowland to mountain biomes or their remnants. Only very few Chordeumatida and Julus species seem to occur solely in the subalpine to alpine environments and thus may provisionally be considered as high-montane elements. Ongoing and future research on the millipedes of the Caucasus, especially in cave and montane environments, will undoubtedly allow for many more novelties and details of the diversity and distribution of Georgia\’s Diplopoda to be revealed or refined.

A new, giant species of Trachyjulus from a cave in southern Thailand is described, illustrated, and compared to morphologically closely related taxa.

Phylogenetic trees, both rooted and unrooted, based on a concatenated dataset of the COI and 28S genes of nine species of Cambalopsidae (Trachyjulus, Glyphiulus, and Plusioglyphiulus), strongly support the monophyly of Trachyjulus and a clear-cut divergence between T. magnus sp. nov. and T. unciger in revealing very high average p-distances of the COI gene (20.80\–23.62\%).
