The authors describe five new species of Pristionchus from Japan and Hongkong. Scarab beetle samplings in Hongkong identified P. hongkongensis sp. n. and P. neolucani sp. n., representing the first beetle-associated Pristionchus species from China. Surprisingly, samplings of millipedes in Japan revealed a previously unknown association of Pristionchus nematodes with these arthropods. Specifically, the authors found three previously known Pristionchus species, P. arcanus, P. entomophagus, and P. fukushimae on Japanese millipedes. In addition, the authors found three new Pristionchus species on millipedes, which are described as P. riukiariae sp. n., P. degawai sp. n., and P. laevicollis, sp. n., the latter of which was also found on stag beetles. These species are most closely related to P. maxplancki, P. japonicus, and P. quartusdecimus and belong to the pacificus species-complex. The authors describe all species based on morphology, morphometrics, and genome-wide sequence analysis. Mating experiments indicated that all species are reproductively isolated from each other and in contrast to the species of the “pacificus species-complex sensu stricto” they do not form F1 hybrids.
