The Thyropygus opinatus subgroup (Diplopoda: Harpagophoridae) of the T. allevatus group in Thailand is revised. Based on a phylogenetic analysis of mtDNA sequence data, it is merged with the T. bifurcus subgroup to form an extended T. opinatus subgroup. Nine new species are described: Thyropygus cimi sp. nov. and T. forceps sp. nov. from Nakhonsrithammarat Province, T. culter sp. nov., T. planispina sp. nov., T. undulatus sp. nov. and T. ursus sp. nov. from Krabi Province, T. mesocristatus sp. nov. from Songkhla Province, T. navychula sp. nov. from Phang-Nga Province and T. sutchariti sp. nov. from Phetchaburi Province.

Giant cylindrical millipedes of the family Harpagophoridae, especially species of the genus Thyropygus, are broadly distributed in Thailand and nearby countries. They show a great deal of variation in body size, color patterns and gonopodal characters. Phylogenetic analyses of 26 nominate species from six genera in the subfamilies Harpagophorinae and Rhynchoproctinae, as well as nine new morphotypes (regarded as new species), were performed with the DNA sequences from two mitochondrial gene fragments (16S rRNA and COI). The genus Thyropygus (Harpagophorinae) was recovered as monophyletic under all analyses, whilst the representatives of Rhynchoproctinae also formed a monophyletic group. However, the analyses suggested that the tribe Gonoplectini should be elevated to a separate subfamily, Gonoplectinae. The molecular analyses were largely (but not totally) congruent with, and so supported the usefulness of, gonopodal characters for the classification and identification of harpagophorid millipedes, and additionally supported previous studies on the delimitation of species and subgroups. This is the first molecular study inside the family Harpagophoridae and provides the basis for further studies of the evolutionary processes and biogeographic patterns of millipedes in Southeast Asia.

A new millipede species of the genus Sechelleptus Mauri\ès, 1980 is described and illustrated from Mayotte Island, Indian Ocean. This new species, S. arborivagus sp. nov., found on trees, looks particularly similar to the sympatric S. variabilis VandenSpiegel \& Golovatch, 2007, but is much larger and has a very different ecological behavior. Phylogenetic analyses based on a concatenated dataset of the COI and 16S rRNA genes and including nine species of Spirostreptidae (including Sechelleptus, Doratogonus Attems, 1914, Bicoxidens Attems, 1928 and Spirostreptus Brandt, 1833), strongly support the monophyly of Sechelleptus. Despite the similarity of their genitalia, the molecular analyses also reveal a clear-cut genetic divergence between S. arborivagus sp. nov. and S. variabilis (22.55\% for COI and 6.63\% for 16SrRNA) and further suggest the presence of a higher diversity within the genus Sechelleptus on Mayotte.

The genus Carlogonus Demange, 1961, is diagnosed, and its relationship with other members of the Harpurostreptini Hoffman, 1980 is discussed. A new species, Carlogonus gayathri sp. nov. is described and illustrated from the southern Indian State of Kerala, and its DNA barcoding data is presented. Phylogenetic analysis based on mtDNA sequence data revealed that Carlogonus is sister-taxon to Thyropygus Pocock, 1894. Two species-groups are recognised in Carlogonus: the exaratus-group is characterised by a single tibial spine on the gonopod, while the acifer-group has paired tibial spines. A dichotomous key is presented for the known Carlogonus spp., and the current distribution of the genus is mapped.
