摘要

根据在日本相模湾850米深处采集的2个标本,描述了一种新的动物科鱼类——natsushima Andriashevia natsushimae(日文名称:Natsushimachojyagenge)。这种鱼没有胸鳍和腹鳍,表明它是安德里亚鱼。它有一个圆形的身体和一个中等大小的嘴,与之形成鲜明对比的是,安德里亚什维亚有一个扁平的身体和一个大嘴巴。基于16S核糖体RNA (16S rRNA)序列的系统发育树表明,该物种在鳗类进化的早期阶段发生了转移。

Characterization of Andriashevia natsushimae, a new species of eelpout (Pisces, Perciformes: Zoarcidae) from Sagami Bay, Japan, and its phylogenic status as inferred from 16S rRNA
A new zoarcid fish, Andriashevia natsushimae (Japanese name: Natsushimachojyagenge), is described on the basis of 2 specimens collected in Sagami Bay, Japan, at the depth of 850 m. This species has no pectoral fins and no pelvic fins, indicating it to be Andriashevia. It has a round body and a moderate-sized mouth in contrast to Andriashevia aptera which has a flat body and a large mouth. Phylogenic tree based on 16S ribosomal RNA (16S rRNA) sequence indicates the species had diverted at the early stage in the evolution of eelpouts.
