Studies on the digenean parasites of deep-sea (> 200 m depth) teleosts are reviewed and two case study generic phylogenies are presented based on LSU rDNA and ND1 mtDNA sequences. The phylogeny of the lepocreadiid genus Lepidapedon, the most common deep-sea digenean genus, is not clearly resolved as the two gene trees are not compatible. It can be inferred, however, that the genus has radiated in the deeper waters off the continental shelf, mainly in fishes of the gadiform family Macrouridae. Steringophorus, a fellodistomid genus, is better resolved. In this case a deep-sea radiation is also indicated, but the pattern of host-specificity is not clear, with evidence of much host-switching. Results of studies of the parasites of the macrourid fish Coryphaenoides (Nematonurus) armatus from various depths have reinforced recent views on the lack of zoned depth-related communities in the deep-sea. The diversity of deep-sea digeneans is relatively low with only 18 families (of about 60) reported. Little, or nothing, is known from most deep-sea areas and nothing from trenches and mid-ocean ridge systems.
本文综述了关于深海（深度>200米）硬骨鱼类复殖吸虫寄生虫的研究，并基于 LSU rDNA 和 ND1 mtDNA 序列给出了两个案例研究的类属系统发育树。最常见的深海复殖吸虫类属 Lepidapedon 的系统发育尚未明确解析，因为两个基因树并不一致。然而，可以推断该类属是在大陆架以外更深水域辐射演化而来的，主要寄生于鳕形目长尾鳕科鱼类。 Fellodistomid 类属 Steringophorus 的解析度更高。在这种情况下，也表明了其在深海中的辐射演化，但宿主特异性模式尚不清楚，有大量宿主转换的证据。对不同深度的长尾鳕科鱼类长吻深海鳕（Nematonurus）armatus 的寄生虫研究结果，强化了近期关于深海缺乏与深度相关的分区群落的观点。深海复殖吸虫的多样性相对较低，仅报道了约60个科中的18个科。大多数深海区域所知甚少，而海沟和大洋中脊系统则一无所知。
