摘要:
通过整理近年来中国科学院海洋研究所采集的深海海参标本,发现了"蛟龙"号载人潜水器在南海珍贝海山水深2463m处采集的1号蝶参科标本,经鉴定为一个新记录属底游参属Benthodytes Théel,1882的一个新记录种西伯加底游参Benthodytes sibogae Sluiter,1901。西伯加底游参与底游参属其他物种的显著差异在于其背部有5-6对大疣,沿背部步带区近乎对称的排列为两行。本文对新记录种的外部形态特征进行了详细的描述,与该种的模式标本进行了分类学讨论,提出背部大疣的数量及排列方式为该属物种区分的重要依据。在对骨片进行超微结构研究时发现,该种背部疣足的骨片与背部和腹部体壁骨片在大小、中央突起的高度和分叉部位上有较大差异,此前的报道未对疣足骨片进行过描述,本文对此进行了补充。

Abstract:
A psychropotid species, Benthodytes sibogae Sluiter, 1901, collected from Zhenbei Seamount from the South China Sea (at the depth of 2463m) was recognized when identifying the deep-sea specimens housed in Marine Biological Museum, Chinese Academy of Sciences. This is the first species recorded from Chinese waters within genus Benthodytes Théel, 1882. Detailed descriptions of its external feature were provided. Benthodytes sibogae is significantly different from other species of Benthodytes in having five or six pairs of large dorsal papillae arranged in two rows along the dorsum and evenly distributed. Observation of the ultra structure showed that the deposits of papillae differed from those of dorsal and ventral in size and height of the central apophyses, and the bifurcate positions of apophyses. In addition, the morphological characters of papillae deposits were illustrated for the first time. The taxonomic status of this species was compared with the type materials of Benthodytes sibogae Sluiter, 1901 and Benthodytes hystrix Sluiter, 1901. It shows that the number and arrangement of large papillae are important taxonomic features in diagnosing species of Benthodytes.
