Three species in genus Sabatieria and one in genus Cervonema from the East China Sea were recorded. S. breviseta is
characterized by uniformly punctuated coarse dots, large amphids of 5.5 turns (?) and prominent gubernaculum median piece. The
characters of S. breviseta agree quite well with the European original descriptions and only differ in the male amphid turns (5.5 vs.
4.0 turns) and unmodified preanal supplements (5-7 vs. 6). S. pulchra can be recognized by amphid 2.75 turns, irregularly arranged
lateral dots, and the first three supplements anterior to the anus, which are more widely spaced than the following ones. The excretory
system of S. breviseta and S. pulchra shows sexual dimorphism. S. celtica is defined by amphids 2.00-2.25 turns, weakly developed
pharyngeal bulb, curved apophyses and 12-13 conspicuous supplements. C. deltensis is characterized by amphids 4.75 turns, ovate
pharyngeal posterior bulb, sperm dimorphism, 7 thin preanal supplements, and long tail cylindrical portion (50%-53% of tail length).
All the three Sabatieria species are for the first time recorded in Chinese waters. C. deltensis was originally isolated from the Bohai
Sea and Yellow Sea and newly recorded in the East China Sea.
