Lithobius (Ezembius) tetraspinus (Lithobiomorpha: Lithobiidae), recently discovered from Hami City, Xinjiang Autonomous Region, NW China, is described. Morphologically this species resembles L. (E.) sibiricus, Gersfeldt, 1858, but is distinguishable by a different coxal pore formula, absence of accessory spurs on leg 15, morphology of the second article of the female gonopod, and legs 14 plectrotaxy. A table of the main morphological characters of Chinese Lithobius (Ezembius) species is presented.

Lithobius (Ezembius) varioporus (Lithobiomorpha, Lithobiidae), recently discovered from Longquanguan Town, Fuping County, Baoding City, Hebei Province, China, is described. Morphologically it resembles to Lithobius (Ezembius) laevidentata Pei, Ma, Hou, Zhu & Gai, 2015 from the Xinjiang Autonomous Region, but can be easily distinguished from the latter by the Tömösváry's organ, slightly smaller than the adjoining ocelli, no secondary sexual modifications on male tibia 14 and 15, posterior accessory spine of legs 14 and 15 present and the number of coxal pores varying considerably from three to eight. The main morphological characters of the known Chinese species of the subgenusEzembius Chamberlin, 1919 based on adult specimens are presented.

The mandibles and the first maxillae of 37 species of the family Lithobiidae (Myriapoda, Chilopoda) were investigated and compared to provide a structural overview and evaluate their significance for the systematics of the family. The species sampling focused on the genus Lithobius, examining 33 species of four subgenera (Lithobius, Monotarsobius, Sigibius, Ezembius), as this genus represents about half of the known diversity of Lithobiidae, including more than 500 assigned species and subspecies. The microstructures on the mandibular gnathal edge and the first maxillary telopodites and coxal projections were studied using scanning electron microscopy.

Lithobius (Ezembius) longibasitarsus and Lithobius (Ezembius) datongensis (Lithobiomorpha: Lithobiidae), recently discovered from Qinghai-Tibet Plateau, China, are described. A key to the species of the subgenus Ezembius in China is presented. The partial mitochondrial cytochrome oxidase subunit I barcoding gene was amplified and sequenced for eight individuals of the two new species and the dataset was used for molecular phylogenetic analysis and genetic distance determination.
