Two new subgenera of the genus Syphacia (Nematoda: Oxyuridae) are proposed for two new species collected from the caecum of Eropeplus canus, an endemic murid of Sulawesi, Indonesia. Syphacia (Rumbaisyphacia) kumis, new subgenus and new species has setiferous apical margin of pharynx in both sexes, and Syphacia (Segienamsyphacia) yuniae, new subgenus and new species has a hexagonal oral opening in female and an egg with an operculum located closer to equator, being readily distinguished from other congeners hitherto known. The peculiar morphology of these species suggests that they belong to different lineages from that of Syphacia spp. recorded so far from Sulawesi. They might have been introduced with an ancestral murid linking Eropeplus and Lenothrix, one of the most primitive rats on Sundaland, and coevolved in Sulawesi.
