Hitherto, the millipede genus Apeuthes (family Pachybolidae, subfamily Trigoniulinae) was only known from three species described in Vietnam based on morphological characters. The present study uses two partial mitochondrial gene fragments (cytochrome c oxidase I (COI) and 16S ribosomal RNA) and morphology to define four new Apeuthes species from Malaysia, Thailand and Vietnam: A. fimbriatus, sp. nov., A. longeligulatus, sp. nov., A. pollex, sp. nov. and ?A. spininavis, sp. nov. The intraspecific COI sequence divergence of two Apeuthes species is 3\–7\% (mean: 5\%) and the interspecific divergence of five species is 11\–16\% (mean: 13.7\%). All members of the genus share unique male characters, viz the posterior gonopod telopodite with several dentate, serrate or tuberculate lamellae in a boat-like cavity or a boat-like cavity covered with spines. The delimitation of the four new species is supported by the congruence between mitochondrial DNA and morphological data. However, while the monophyly of Trigoniulinae is well supported, the relationships within this subfamily, and particularly among Apeuthes species, including the monophyly of Apeuthes, lack strong support. Therefore assignment of the four new species, and particularly of ?A. spininavis sp. nov., to the genus Apeuthes is tentative and awaits a comprehensive revision of the group.

A new pill millipede, Rhopalomeris nagao sp. nov., is described from Vietnam. It is recognized by the following combination of characters: antennal tip with numerous sensory cones; telopods with short prefemoral and femoral trichosteles, with long, straight and acute tuberculiform femoral process, and with shorter lobuliform tibial process; syncoxial lobe being slightly concave medially, syncoxial horns being longer than lobe. A fragment of the cytochrome c oxidase subunit I (COI) gene is also provided for the new species. The K2P genetic distance of the COI between the new species and other Vietnamese glomeridans is from 10.7\% to 16.9\%. Two genera, Hyperglomeris and Hyleoglomeris, are considered to be non-monophyletic, but more data and samples will be needed for confirmation.

Abstract: This contribution is devoted to new records of three known, and to descriptions of three new, species from Vietnam and China: Hedinomorpha barbata sp.n. from Sichuan, and both Kronopolites typicus sp.n. and Tylopus uncinatus sp.n. from Yunnan. A key is presented to all 11 species of Kronopolites known to date.

A new genus and five new species of glomerid millipedes are described from Vietnam: Tonkinomeris napoensis, new genus \& new species, from Ha Giang Province; Hyleoglomeris coloratoides, new species from Huong Son District, Ha Tinh Province; Hyleoglomeris lobus, new species from Cuc Phuong National Park, Ninh Binh Province; Hyperglomeris simplex, new species from Vinh Phuc Province; and Rhopalomeris sauda, new species from Bac Kan and Vinh Phuc Provinces. New distributional records and detailed morphological data are provided for Peplomeris magna Golovatch, 1983. A key to the genera of the family Glomeridae is provided for the Vietnamese fauna. The current status of glomerid systematics is discussed.

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 pill millipede species, namely Hyleoglomeris hoanglien sp. nov. and H. fanxipan sp. nov., are described from high elevations (approximately 2,800\–2,900 m) of the Hoang Lien National Park, northern Vietnam. A new species, H. hoanglien sp. nov. is clearly distinguished by the telopods being short, stout and incrassate, femora strongly condensed, tibia without modifications, syncoxital lobe bifid trapeziform, and syncoxital horns with an apical seta and a spine. Hyleoglomeris fanxipan sp. nov., is diagnosed by the telopods being long and robust, tibia without modifications, syncoxital lobe roundly trapeziform, and syncoxital horns truncated at tip. COI-based DNA barcodes of the two species are also provided for the first time in the genus Hyleoglomeris. The K2P genetic distance between the two new species is 0.148. In addition, an identification key to the Vietnamese Hyleoglomeris species is also provided.
