报道了印度尼西亚苏拉威西岛特有虫种中2个新种：分别寄生于细尾绦虫盲肠和细尾绦虫盲肠的细尾绦虫（Syphacia taeromyos sp. n.）和细尾绦虫（s.p oruromyos sp. n.）。它们很容易与印度尼西亚-澳大利亚地区记录的所有同类区分，具有圆形的头板，雄性的水疱侧翼，雄性的排泄孔位于后方，和/或缺乏颈椎翼。细尾虫（Syphacia paruromyos, s）与细尾虫（S.）的不同之处在于，雄性的尾巴有鞭状附属物，排泄孔与外阴之间的相对距离较长，卵较大。两性的圆形头板和雄性的水疱侧翼是迄今为止已知的苏拉威西岛特有梅毒物种的共同形态学特征，这表明它们起源于共同的祖先，并在孤立的岛屿环境中与宿主进化。
Two new species of Syphacia (Nematoda: Oxyuridae) are described from endemic murids of Sulawesi, Indonesia: Syphacia(Syphacia)taeromyos sp. n. and S.(S.)paruromyos sp. n. parasitic in the caecum of Taeromys celebensis and Paruromys dominator, respectively. They are readily distinguished from all of the congeners recorded from Indonesia–Australian regions by having a round cephalic plate, vesicular lateral alae in the male, posteriorly positioned excretory pore in the male, and/or lacking cervical alae. Syphacia (S.) paruromyos differs from S. (S.) taeromyos by having a whip-like tail appendage in the male, longer relative distance between excretory pore and vulva, and larger eggs. The round cephalic plate in both sexes and developed vesicular lateral alae in the male are morphological traits common in endemic Syphacia species hitherto known from Sulawesi murids, suggesting that they have derived from a common ancestor and evolved with their hosts in the isolated insular environment.
