| 摘 要： | 记述了渤海中部在站位DA18、水深27m采到的海洋线虫一新种,渤海海线虫Thalassironus bohaiensis sp nov该新种的个体大小和De Man比值(a.b.c)与Thalassiro-nus bipartitus(Wieser,1953)十分相似,但雄性副交接刺的结构,两种有显著的差异。新种的副交接刺末端钝且内凹,在腹侧近末端有一明显的小突起,而相近种的副交接刺末端尖锐,没有任何突起。此外,新种雄性交接刺长度也与相近种有明显的差别(62—67μmvs 52μm)列表比较了新种与相近种以及该属目前已报导的其他三个种的详细形态学特征。模式标本保存在青岛海洋大学海洋生物系。

| Abstract: | A new free-living marine nemarode species is described from station DA18 27m depth, the central part of the Bohai Sea, China Thalassironus bohaiensis n. sp. is similar to Thalassironus bipartitus (Wieser, 1953) from which it can be separated by shorter cephalic setae, tail length, relatively longer spicule length and gubcrnacular structure. A tabular key to species of the genus Thalassironus is given. The types are deposited in the Department of Marine Biology, Ocean University of Qingdao. |
