粘盲鳗是一种古老的底栖海洋颅骨类动物,分布于世界各地的深水或冷水中。在 83 个有效物种中,有 4 个来自加拉帕戈斯群岛:Eptatretus bobwisneri、E.格鲁瑟里,E. mccoskerian和Rubicundus湖畔。在最近一次对群岛的考察中,收集到了六种盲鳗,其中包括四种未描述的Eptatretus属(Eptatretus goslineisp. nov.)和Myxine(Myxine greggisp. nov.、M. martiniisp. nov.和M. phantasmasp. nov.)。在本文中,我们对来自加拉帕戈斯群岛的八种盲鳗进行了回顾,包括新的诊断和所有物种的识别关键。Myxine phantasmai 的非凡之处在于它是唯一已知完全缺乏黑色素的 Myxine 物种。我们的物种描述是基于形态学和分子分析。基于分子数据的系统发育假说表明,加拉帕戈斯盲鳗起源于来自多达五个不同祖先谱系的多个独立的岛屿殖民。地质上年轻的加拉帕戈斯群岛存在大量特有盲鳗,这表明全球盲鳗的多样性尚有待发现。
Hagfishes are an ancient group of benthic marine craniates that are found in deep or cold waters around the world. Among the 83 valid species, four are described from the Galapagos Islands:Eptatretus bobwisneri,E. grouseri,E. mccoskeriandRubicundus lakeside.During a recent expedition to the archipelago, six species of hagfishes were collected, including four undescribed species of the generaEptatretus(Eptatretus goslineisp. nov.) andMyxine(Myxine greggisp. nov.,M. martiniisp. nov.andM. phantasmasp. nov.). In this paper, we provide a review of the eight species of hagfishes from the Galapagos Islands, including new diagnoses and an identification key for all species.Myxine phantasmais remarkable in that it is the only species ofMyxineknown to completely lack melanin-based pigments. Our species delineations were based on both morphological and molecular analyses. A phylogenetic hypothesis based on molecular data suggests that Galapagos hagfishes arose from multiple independent colonisations of the islands from as many as five different ancestral lineages. The large number of endemic hagfishes in the geologically young Galapagos Islands suggests that there is much global hagfish diversity yet to be discovered.
