biostudies-literatureUnknown1108Zhao YThe <i>javanicus</i>-group of <i>Glyphiulus</i> is re-assessed and its Chinese component species are presently divided between the following two newly-circumscribed species groups, i.e. the <i>formosus</i>- and the <i>sinensis</i>-group. The two can be differentiated, based on the diagnostic characters of the first pair of legs in the male. In addition, metatergal crests being complete and the carinotaxy formula on the collum being I-III+P+M are only characteristic of the <i>formosus</i>-group. A molecular phylogeny of the genus, based on DNA sequencing of four gene fragments of four genes, allows for <i>Glyphiulus</i> to be recovered as a monophyletic group, the phylogenetic relationship being ((Clade A, Clade B), Clade C). Molecular evidence is fully congruent with the morphological one.ZooKeys89-118https://www.ebi.ac.uk/biostudies/studies/S-EPMC9848670biostudies-literatureRevision of the <i>javanicus</i> species group of the millipede genus <i>Glyphiulus</i> Gervais, 1847, with descriptions of five new species from China (Diplopoda, Spirostreptida, Cambalopsidae).PMC9848670Guo WRGolovatch SILiu WXZhao YfalseRevision of the <i>javanicus</i> species group of the millipede genus <i>Glyphiulus</i> Gervais, 1847, with descriptions of five new species from China (Diplopoda, Spirostreptida, Cambalopsidae).The <i>javanicus</i>-group of <i>Glyphiulus</i> is re-assessed and its Chinese component species are presently divided between the following two newly-circumscribed species groups, i.e. the <i>formosus</i>- and the <i>sinensis</i>-group.
