Syphacia (Syphacia) rifaii sp. n. (Nematoda: Oxyuridae) is described from endemic Bunomys chrysocomus and Bunomys prolatus (Rodentia: Muridae) on Sulawesi Island, Indonesia. The new species is closest morphologically to Syphacia (Syphacia) sulawesiensis , parasitic in Rattus xanthurus from Sulawesi Island, by having large vesicular lateral alae in males, but is readily distinguished by having a smaller body, a round cephalic plate in both sexes, the absence of lateral alae in females, a longer relative distance between excretory pore and vulva, and smaller eggs. Syphacia (S.) rifaii is surmised to be a specific parasite of Bunomys spp. and has evolved from a common ancestor with S. (S.) sulawesiensis on Sulawesi Island.
里法伊氏管圆线虫（Syphacia rifaii）新种（线虫纲：尖尾科）是在印度尼西亚苏拉威西岛的特有种金黄布氏鼠（Bunomys chrysocomus）和长布氏鼠（Bunomys prolatus）（啮齿目：鼠科）体内发现并描述的。该新种在形态上与寄生在苏拉威西岛黄胸鼠（Rattus xanthurus）体内的苏拉威西管圆线虫（Syphacia (Syphacia) sulawesiensis）最为接近，雄性均具有大的泡状侧翼，但通过以下特征可轻易区分：虫体较小，两性均具有圆形头板，雌性无侧翼，排泄孔与阴门之间的相对距离较长，且虫卵较小。推测里法伊氏管圆线虫（Syphacia (S.) rifaii）是布氏鼠属（Bunomys spp.）的特异性寄生虫，并且是与苏拉威西岛上的苏拉威西管圆线虫（S. (S.) sulawesiensis）由共同祖先进化而来。
