The publication entitled \u201c<strong>Morphological and mitochondrial DNA data reshuffle the taxonomy of the genera Atopochetus Attems, Litostrophus Chamberlin and Tonkinbolus Verhoeff (Diplopoda: Spirobolida: Pachybolidae), with descriptions of nine new species.<\/strong>\u201d<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\"><strong>Abstract:<\/strong> Species-level taxonomy and phylogeny of two genera of South-East (SE) Asian pachybolid millipedes are analysed with a combination of morphological characters and DNA sequences (two mitochondrial gene fragments: <em>COI <\/em>and <em>16S<\/em> rRNA). Strong support is found for the genera <em>Litostrophus<\/em> Chamberlin, 1921 and <em>Atopochetus<\/em> Attems, 1953 and for a clade consisting of <em>Litostrophus<\/em> + <em>Atopochetus<\/em>. Four species of <em>Litostrophus<\/em> are recognised and (re)described: <em>L. segregatus<\/em> Chamberlin, 1921 (type species of the genus), <em>L. scaber<\/em> (Verhoeff, 1938), comb. nov., <em>L. chamaeleon<\/em>, sp. nov. and <em>L. saraburensis<\/em>, sp. nov. The genus <em>Tonkinbolus<\/em> Verhoeff, 1938 (type species <em>T. scaber<\/em> Verhoeff, 1938) is synonymised under <em>Litostrophus<\/em>. <em>Atopochetus<\/em> (type species A. <em>rubropunctatus<\/em> Attems, 1953), hitherto considered a dubious synonym of <em>Aulacobolus<\/em> Pocock, 1903, is re-instated for several species until now placed in <em>Tonkinbolus<\/em> and seven new species. All in all, 10 species of <em>Atopochetus<\/em> are (re)described: <em>A. dollfusii<\/em> (Pocock, 1893) (= <em>Aulacobolus rubropunctatus<\/em> Attems, 1938, syn. nov.), <em>A. moulmeinensis<\/em> (Pocock, 1893), <em>A. sumatranus<\/em> (Carl, 1906) (= <em>Trachelomegalus laciniatus<\/em> Attems, 1937, syn. nov.), <em>A. anaticeps,<\/em> sp. nov., <em>A. helix<\/em>, sp. nov., <em>A. setiferus<\/em>, sp. nov., <em>A. spinimargo<\/em>, sp. nov., <em>A. truncatus<\/em>, sp. nov., <em>A. uncinatus<\/em>, sp. nov. and <em>A. weseneri<\/em>, sp. nov. Three species recently included in <em>Tonkinbolus <\/em>are left incertae sedis because they are based exclusively on female type specimens: <em>Spirobolus capucinus<\/em> Porat, 1896, <em>S. caudulanus<\/em> Karsch, 1881 and <em>S. macrurus<\/em> Pocock, 1893. The results of the DNA analysis (<em>COI<\/em> and <em>16S<\/em> rRNA) are congruent with morphological (gonopodal) characters in terms of delimitation of species of <em>Litostrophus<\/em> and <em>Atopochetus<\/em>. This is the first DNA study of SE Asian Pachybolidae and as such it provides a basis for further evolutionary and biogeographic studies of SE Asian millipedes. <\/pre>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:66.66%\">\n<p><strong>1.
