Background: The myriapod fauna of China is still poorly known and very little attention has been paid to the study of Lithobiomorpha, with only 100 species and subspecies known from the country. Altogether, 11 species of subgenusMonotarsobius have been recorded from China, but only two of them have been reported from Hebei Province. Herein, a new species recently discovered in the Hebei Province, China, is described and illustrated.
New Information: A new lithobiids species Lithobius (Monotarsobius) tetrasulcus sp. n. is described and illustrated from Hengshui Lake National Nature Reserve, Hebei Province, China. The new species is compared with Lithobius (Monotarsobius) crassipes Koch, 1862 from Taiwan, China. It can be easily distinguished from congeners by having a longitudinal groove on the dorsal side of the femur and tibia of the male legs 14 and 15, only having a posterior spine on the dorsal side of femur of legs 12-15, lacking robust spines lying dorsally on the external margin on the second article of the female gonopods and the third article of the female gonopods having a bidentate apical claw.

Phylogenetic analyses based on molecular and morphological data were conducted to shed light on relationships within the mostly Palaearctic/Oriental centipede family Lithobiidae, with a particular focus on the Palaearctic genus Lithobius Leach, 1814 (Lithobiidae, Lithobiomorpha), which contains >500 species and subspecies. Previous studies based on morphological data resolved Lithobius as nonmonophyletic, but molecular-based phylogenetic analyses have until now sampled few species. To elucidate species inter-relationships of the genus, test the validity of its classification into subgenera, and infer its relationships with other Lithobiidae, we obtained molecular data (nuclear markers: 18S rRNA, 28S rRNA; mitochondrial markers: 16S rRNA, COI) and 61 morphological characters for 44 species of Lithobius representing four of its eight subgenera and nine other representatives of Lithobiidae.

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.

Recent collecting on the island of La Palma has yielded two new records, Lithobius (Monotarsobius) crassipesoides and Lithobius (Lithobius) melanops, the former also being new to the Canary Islands and is recorded for the first time after its recent description. We additionally provide species records for the lithobiomorph species of the island, with new locality data and a distribution map based on recent and literature records. We update the checklist of the lithobiomorph species of the Canaries and document all the newly collected species.

The total species richness in the myriapod assemblages of the lowland Altais near Charyshskoe Village, Altai Province, southwestern Siberia, Russia is estimated to be at least 19 species from ten genera, eight families, five orders, and two classes. The following species are new to SW Siberia: Lithobius (Ezembius) ostiacorum Stuxberg, 1876, Stuxberg, 1876, and L. (Monotarsobius) nordenskioeldii Stuxberg, 1876, while L.
