The genus Nannarrup Foddai, Bonato, Pereira \& Minelli, 2003 is a monotypic genus established on the basis of the possibly introduced species N. hoffmani Foddai, Bonato, Pereira \& Minelli, 2003, from New York, USA. In the present study, in a field survey conducted throughout Japan, Nannarrup-like specimens were collected from Honshu, Shikoku, and Kyushu. These specimens clearly showed the diagnostic characteristics of the genus but were morphologically distinct from N. hoffmani. Furthermore, morphological analysis and DNA barcoding revealed that these specimens could be assigned to two distinct undescribed species. On the basis of these results, N. innuptus Tsukamoto, sp. nov. and N. oyamensis Tsukamoto, sp. nov. are described. The three Nannarrup species can be distinguished from each other on the basis of the following combination of characteristics: presence or absence of a pair of smooth or weakly areolate areas along the posterior part of the paraclypeal sutures; the width-to-length ratio of the denticle on the trochanteroprefemur; the pigmentation of the denticle on the tarsungulum. Moreover, the field survey resulted in the collection of exclusively female specimens of N. innuptus Tsukamoto, sp. nov., which shows the possibility of parthenogenesis of this species.

The genus Oxidus Cook, 1911 is revised to contain five species, O. avia (Verhoeff, 1937), O. gigas (Attems, 1953), O. gracilis (C.L. Koch, 1847), O. riukiaria (Verhoeff, 1940), and \“species inquirenda\” O. obtusus (Takakuwa, 1942). A cosmopolitan species, O. gracilis, is widely found in temperate and sub-tropical regions over the world, but other species have limited distribution in restricted regions, e.g., O. gigas in northern Vietnam, O. riukiaria and O. avia in the Ryukyu Islands (Japan). Four species, O. gracilis, O. riukiaria, O. avia and O. gigas, are confirmed as different from each other in gonopod characters, coloration and body size. The status of the last species, O. obtusus, is still doubtful and requires examination of further fresh material. The phylogenetic relationships among species of Oxidus is analyzed using two fragments of the mitochondrial genes COI (Cytochrome c Oxidase subunit I) and 16S rRNA. Three species of Oxidus are clearly separated from each other; O. gigas and O. gracilis form a monophyletic sister group with O. riukiaria. The genus Oxidus is also monophyletic and more closely related to the genus Tylopus Jeekel, 1968 than to the genera Sellanucheza Enghoff, Golovatch \& Nguyen, 2004 or Kronopolites Attems, 1914. In addition, an identification key to species of Oxidus is provided.

Species assigned to the anopsobiine centipede genera Anopsobius Silvestri, 1899, and Dichelobius Attems, 1911, are widely distributed on fragments of the Gondwanan supercontinent, including temperate and tropical Australia, New Zealand, New Caledonia, the Cape region of South Africa, and southern South America. Phylogenetic relationships between Australasian and other Gondwanan Anopsobiinae are inferred based on parsimony and maximum likelihood analyses (via direct optimisation) of sequence data for five markers: nuclear ribosomal 18S rRNA and 28S rRNA, mitochondrial ribosomal 12S rRNA and 16S RNA, and the mitochondrial protein-coding cytochrome c oxidase subunit I. New molecular data are added for Anopsobius from South Africa and New Zealand, Dichelobius from New Caledonia, and a new species from Queensland, Australia, Dichelobius etnaensis, sp. nov. The new species is based on distinctive morphological and molecular data. The molecular phylogenies indicate that antennal segmentation in the Anopsobiinae is a more reliable taxonomic character than is spiracle distribution. The former character divides the Gondwanan clade into a 17-segmented group (Dichelobius) and a 15-segmented group (Anopsobius). Confinement of the spiracles to segments 3, 10 and 12 has at least two origins in the Gondwanan clade. The area cladogram for Dichelobius (Queensland (Western Australia + New Caledonia)) suggests a relictual distribution pruned by extinction.

Three forms of Japanese Eudigraphis (Penicillata, Polyxenidae), which have long been treated as subspecies of Eudigraphis takakuwai (Miyosi, 1947), i.e., E. t. takakuwai (Miyosi, 1947), E. t. nigricans (Miyosi, 1947), and E. t. kinutensis (Haga, 1950), are raised here to three distinct species. Overlap of their distributional ranges over wide areas of Japan was confirmed, and molecular phylogeny using both nuclear (ITS2) and mitochondrial (COI) DNA testified monophyly of each of the three forms. Additionally, the three forms can be easily distinguished from one another by body size, coloration, and habitat, though species identification for the specimens preserved in ethanol is often difficult due to their morphological similarity other than coloration and size. Description of some so-far neglected morphological characters were provided with some SEM photos to supplement knowledge on taxonomy and morphology of the family.
