摘要:
对首次发现于我国南海海域Sabatieria Rouville,1903的三个种进行了描述。其中,弯刺萨巴线虫Sabatieria curvispiculata Gagarin,2013主要特征为:头刚毛较短(3μm),角皮具有不规则的侧装饰点,交接刺细长且双弯曲,雄体具有15个小的乳突状肛前辅器。锥尾萨巴线虫Sabatieria conicauda Vitiello,1970主要特征为:具有短的锥状尾,角皮具有侧装饰点,交接刺弯曲,前半部分较宽,中间有角质化的隔膜,后半部较窄且没有隔膜,雄体具有9个小孔状的肛前辅器。迁徙萨巴线虫Sabatieria migrans Jensen&Gerlach 1977主要特征为:头刚毛较长(22μm),交接刺细长且弯曲,近端具有中间隔膜,雄体具有23个小的肛前辅器。

Abstract:
Three new records of free-living marine nematode species from marine sediments in the South China Sea, are described and documented. Sabatieria curvispiculata Gagarin, 2013 is characterized by short cephalic setae (3μm), cuticle with lateral differentiation, spicule slender and double curved, males with 15 precloacal ventromedian supplements, in the form of cuticular pores. Sabatieria conicauda Vitiello, 1970 is characterized by the combination of short and conical tail, cuticle with lateral differentiation, spicule slightly curved, broad anterior half with median strip and posterior half narrow without median strip, males with 9 fine ventral precloacal supplements. Sabatieria migrans Jensen & Gerlach 1977 is characterized by the combination of very long cephalic seta (22μm), spicule slender, curved and with a median strip at proximal end, males with 23 fine ventral precloacal supplements.
