    The dragon millipede genus Desmoxytes s.l. is split into five genera, based on morphological characters and preliminary molecular phylogenetic analyses. The present article includes a review of Desmoxytes s.s., while future articles will deal with Hylomus Cook and Loomis, 1924 and three new genera which preliminarily are referred to as the 'acantherpestes', 'gigas', and 'spiny' groups. Diagnostic morphological characters of each group are discussed. Hylomus is resurrected as a valid genus and the following 33 species are assigned to it: H. asper (Attems, 1937), comb. n., H. cattienensis (Nguyen, Golovatch & Anichkin, 2005), comb. n., H. cervarius (Attems, 1953), comb. n., H. cornutus (Zhang & Li, 1982), comb. n., H. draco Cook & Loomis, 1924, stat. rev., H. enghoffi (Nguyen, Golovatch & Anichkin, 2005), comb. n., H. eupterygotus (Golovatch, Li, Liu & Geoffroy, 2012), comb. n., H. getuhensis (Liu, Golovatch & Tian, 2014), comb. n., H. grandis (Golovatch, VandenSpiegel & Semenyuk, 2016), comb. n., H. hostilis (Golovatch & Enghoff, 1994), comb. n., H. jeekeli (Golovatch & Enghoff, 1994), comb. n., H. lingulatus (Liu, Golovatch & Tian, 2014), comb. n., H. laticollis (Liu, Golovatch & Tian, 2016), comb. n., H. longispinus (Loksa, 1960), comb. n., H. lui (Golovatch, Li, Liu & Geoffroy, 2012), comb. n., H. minutuberculus (Zhang, 1986), comb. n., H. nodulosus (Liu, Golovatch & Tian, 2014), comb. n., H. parvulus (Liu, Golovatch & Tian, 2014), comb. n., H. phasmoides (Liu, Golovatch & Tian, 2016), comb. n., H. pilosus (Attems, 1937), comb. n., H. proximus (Nguyen, Golovatch & Anichkin, 2005), comb. n., H. rhinoceros (Likhitrakarn, Golovatch & Panha, 2015), comb. n., H. rhinoparvus (Likhitrakarn, Golovatch & Panha, 2015), comb. n., H. scolopendroides (Golovatch, Geoffroy & Mauriès, 2010), comb. n., H. scutigeroides (Golovatch, Geoffroy & Mauriès, 2010), comb. n., H. similis (Liu, Golovatch & Tian, 2016), comb. n., H. simplex (Golovatch, VandenSpiegel & Semenyuk, 2016), comb. n., H. simplipodus (Liu, Golovatch & Tian, 2016), comb. n., H. specialis (Nguyen, Golovatch & Anichkin, 2005), comb. n., H. spectabilis (Attems, 1937), comb. n., H. spinitergus (Liu, Golovatch & Tian, 2016), comb. n., H. spinissimus (Golovatch, Li, Liu & Geoffroy, 2012), comb. n. and H. variabilis (Liu, Golovatch & Tian, 2016), comb. n.Desmoxytes s.s. includes the following species: D. breviverpa Srisonchai, Enghoff & Panha, 2016; D. cervina (Pocock,1895); D. delfae (Jeekel, 1964); D. des Srisonchai, Enghoff & Panha, 2016; D. pinnasquali Srisonchai, Enghoff & Panha, 2016; D. planata (Pocock, 1895); D. purpurosea Enghoff, Sutcharit & Panha, 2007; D. takensis Srisonchai, Enghoff & Panha, 2016; D. taurina (Pocock, 1895); D. terae (Jeekel, 1964), all of which are re-described based mainly on type material. Two new synonyms are proposed: Desmoxytes pterygota Golovatch & Enghoff, 1994, syn. n. (= Desmoxytes cervina (Pocock, 1895)), Desmoxytes rubra Golovatch & Enghoff, 1994, syn. n. (= Desmoxytes delfae (Jeekel, 1964)). Six new species are described from Thailand: D. aurata Srisonchai, Enghoff & Panha, sp. n., D. corythosaurus Srisonchai, Enghoff & Panha, sp. n., D. euros Srisonchai, Enghoff & Panha, sp. n., D. flabella Srisonchai, Enghoff & Panha, sp. n., D. golovatchi Srisonchai, Enghoff & Panha, sp. n., D. octoconigera Srisonchai, Enghoff & Panha, sp. n., as well as one from Malaysia: D. perakensis Srisonchai, Enghoff & Panha, sp. n., and one from Myanmar: D. waepyanensis Srisonchai, Enghoff & Panha, sp. n. The species can mostly be easily distinguished by gonopod structure in combination with other external characters; some cases of particularly similar congeners are discussed. All species of Desmoxytes s.s. seem to be endemic to continental Southeast Asia (except the 'tramp' species D. planata). Some biological observations (relationship with mites, moulting) are recorded for the first time. Complete illustrations of external morphological characters, an identification key, and distribution maps of all species are provided.

    Nine new species constituting the 'spiny' group of dragon millipedes are assigned to the new genus Spinaxytes Srisonchai, Enghoff & Panha, gen. n. Seven new species are described from Thailand: S.biloba Srisonchai, Enghoff & Panha, sp. n. and S.palmata Srisonchai, Enghoff & Panha, sp. n. from Surat Thani Province, S.hasta Srisonchai, Enghoff & Panha, sp. n. from Chumphon Province, S.krabiensis Srisonchai, Enghoff & Panha, sp. n. (type species) and S.sutchariti Srisonchai, Enghoff & Panha, sp. n. from Krabi Province, S.uncus Srisonchai, Enghoff & Panha, sp. n., and S.macaca Srisonchai, Enghoff & Panha, sp. n. from Phang Nga Province; as well as one from Malaysia, S.tortioverpa Srisonchai, Enghoff & Panha, sp. n., and one from Myanmar, S.efefi Srisonchai, Enghoff & Panha, sp. n. The new genus is endemic to South Myanmar, South Thailand, and Malaysia, and all new species are restricted to limestone habitats. All were exclusively found living on humid rock walls and/or inside small caves. Complete illustrations of external morphological characters, an identification key, and a distribution map are provided.
