摘要：
A new free-living marine nematode species of the genus Sabatieria was documented from the sediment of the Jiaozhou Bay, Qingdao, China, and it has been named Sabatieria sinica sp. nov. It is characterized by homogeneous cuticle without lateral differentiation, relatively short cephalic setae, spiral amphideal fovea with 2-2.25 turns; thick spicules with a mid constriction or joint, gubernaculum with a long straight dorso-caudal apophyses, and 6-7 prominent papillar precloacal supplements. This new species could be distinguished from other congener species by the combination of its characteristics: body size, length of cephalic setae, number of amphid turns, structures of spicules and gubernaculum, and type and number of precloacal supplements. An update dichotomous key is provided for nine species of pulchra group of Sabatieria including the new species.
