暗纹夜蛾Iheyspa bathcodon sp.11月来自世界上最深的传播中心-加勒比海中开曼传播中心(MCSC)的冯·达姆喷口，深度为2300米。新种由11个标本定义和图示，并简要注明栖息地和已知分布。利用部分COI mDNA区、16S rDNA区和核18S rDNA区的分子系统发育数据分析了该种的系统发育地位，并将其形态与以前所描述的丝状和喷口类群进行了比较。该新种与最接近的喷口种Iheyspa lequios Okutani，Sasaki&Tuchida，2000的区别在于其头部和足部的放射状诊断和附属物结构上的形态差异。暗纹夜蛾Iheyspa bathcodon sp.11月是从热液喷口环境中描述的第十种海龟，也是从最近在MCSC上发现的热液喷口命名的第二个物种。确定MCSC喷口组合的动物群组成将有助于阐明该地区的喷口生物地理。
Iheyaspira bathycodon sp. nov. is described from the Von Damm Vent Field on the world's deepest spreading centre, the Mid-Cayman Spreading Centre (MCSC), Caribbean, at 2300 m depth. The new species is defined and illustrated from 11 specimens, with brief notes on habitat and known distribution. Molecular phylogenetic data from partial COI mDNA, 16S rDNA and nuclear 18S rDNA regions are used to analyse the species’ phylogenetic position and its morphology is compared with previously described skeneid and vent taxa. The new species is distinguished from the most closely allied vent species, Iheyaspira lequios Okutani, Sasaki & Tsuchida, 2000 by morphological differences in radula diagnosis and appendage structure of the head-foot. Iheyaspira bathycodon sp. nov. is the tenth turbinid to be described from a hydrothermal-vent environment and the second species to be named from recently discovered hydrothermal vents on the MCSC. Determining the faunal composition of assemblages at the vent fields of the MCSC will help to elucidate the vent biogeography of the region.
