One new and one known species of the family Comesomatidae were collected from marine sediments in the South China Sea. Cervonema longispicula sp. nov. has stout cephalic setae, elongated and curved spicules with cephalated proximal end, and gubernaculum with hook-like dorsal apophysis that make the new species easily recognizable from the other 18 recorded Cervonema species. Paracomesoma zhangi Huang Huang, 2018 was redescribed based on more specimens of males and females. These specimens are in accordance with the characteristics of holotype from the East China Sea except having more precloacal supplements (30-39), males slightly smaller (not longer than 1710 µm) and with shorter cephalic setae (not longer than 10 μm).
从中国南海的海洋沉积物中采集到了蠕形科的一个新物种和一个已知物种。长刺颈线虫（Cervonema longispicula sp. nov.）具有粗壮的头部刚毛、近端有头部化且细长弯曲的交合刺，以及带有钩状背突的引带，这些特征使得该新物种易于与其他18种已记录的颈线虫物种区分开来。基于更多的雌雄标本对张氏副蠕形线虫（Paracomesoma zhangi Huang Huang, 2018）进行了重新描述。这些标本与来自东海的正模标本特征相符，只是具有更多的泄殖腔前补充器（30 - 39个），雄性稍小（不超过1710 µm）且头部刚毛较短（不超过10 µm）。
