Notothenioidei 亚目的南极龙鱼(Bathydraconidae)仅在南大洋发现,它们的栖息地从水面到数千米深的深海区域多样化。在龙鱼中,中上层的裸龙亚科姐妹物种 Acanthodraco dewitti 和 Psilodraco breviceps 仍然鲜为人知。虽然A.德威蒂斯被认为仅限于南极水域和P。 brevicepsto 是南乔治亚岛特有的,几个P。南极洲沿海地区偶尔有报告发现 breviceps 标本。在这里,我们研究了这两个物种的分子遗传特性及其地理分布。三个线粒体遗传标记(mt-cyb、mt-co1 和 mt-nd2)鉴定出在西南极半岛采集的两种龙鱼幼虫为 A。 dewittiand 表明,所有六个样本均具有可用的遗传数据并报告为 beP。在南极海域采集到的短海藻还有A.德维蒂。这些结果支持了这两个物种的异域分布。 breviceps 是南乔治亚岛和 A. 的特有种。德威蒂是南极水域特有的,可能环极地分布。姊妹种的生物地理学A.德维蒂安德P. brevicepsis 可能与同属姐妹龙鱼物种 Parachaenichthys charcotiand 和 P. brevicepsis 的异域分布相似。这些考虑表明,南极绕极流可能在地理上隔离了两个姐妹物种对的亚南极和南极物种,限制了基因流动并促进了物种形成。此外,我们还提供了 A 的详细描述。 dewittilarvae 提供区分的特征形态特征。德维蒂安德P.短翅幼虫。
Antarctic dragonfishes (Bathydraconidae) of the suborder Notothenioidei are found only in the Southern Ocean where they diversified in habitats from the surface to the bathypelagic zone thousands of meters deep. Among dragonfishes, the pelagic Gymnodraconinae sister speciesAcanthodraco dewittiandPsilodraco brevicepsremain poorly known. AlthoughA. dewittiis thought to be restricted to Antarctic waters andP. brevicepsto be endemic to South Georgia Island, severalP. brevicepsspecimens have occasionally been reported in coastal Antarctica. Here we investigated the molecular genetic identity of the two species and their geographic distribution. Three mitochondrial genetic markers (mt-cyb,mt-co1, andmt-nd2) identified two dragonfish larvae collected on the West Antarctic Peninsula asA. dewittiand showed that all six specimens with available genetic data and reported to beP. brevicepscollected in Antarctic waters were alsoA. dewitti. These results support the allopatric distribution of the two species, withP. brevicepsbeing endemic to South Georgia Island andA. dewittibeing endemic to Antarctic waters, potentially with a circumpolar distribution. The biogeography of the sister speciesA. dewittiandP. brevicepsis likely similar to the allopatric distribution of the congeneric sister dragonfish speciesParachaenichthys charcotiandP. georgianus.These considerations suggest that the Antarctic Circumpolar Current may geographically isolate the sub-Antarctic and Antarctic species of both sister species pairs, limiting gene flow and promoting speciation. Furthermore, we provide a detailed description of theA. dewittilarvae to supply characteristic morphological features differentiatingA. dewittiandP. brevicepslarvae.
