Three Seinura species from Japan with a description of S. shigaensis n. sp. (Tylenchomorpha: Aphelenchoididae)
A preliminary survey of Seinura spp. was conducted in the Kyoto area, Western Japan. The survey yielded four new strains of Seinura spp., including two strains of S. caverna, a strain of S. italiensis, and a strain of an undescribed species. Molecularly, the two strains of S. caverna were nearly ide...

Summary: | A preliminary survey of Seinura spp. was conducted in the Kyoto area, Western Japan. The survey yielded four new strains of Seinura spp., including two strains of S. caverna, a strain of S. italiensis, and a strain of an undescribed species. Molecularly, the two strains of S. caverna were nearly identical to the type strain but showed some minor variations, particularly in the mitochondrial cytochrome oxidase subunit I gene. The small subunit and D2-D3 large subunit sequences of the Japanese strain of S. italiensis were nearly identical and identical to its original description, respectively, and the difference in the small subunit was due to mis-reading of the sequences. The new species, S. shigaensis n. sp., was phylogenetically close to S. caverna and S. persica, although these three species were clearly different phylogenetically. The new species was typologically similar or nearly identical to several other Seinura spp., including S. chertkovi, S. christiei, S. italiensis, S. steineri, and S. tenuicaudata, but it can be distinguished from those species by the morphometric values. Because the new species is phylogenetically very close to S. caverna, it could be a good comparative system for S. caverna as a potential satellite model for the predatory nematode. |
