Abstract

Analysis of 18S rDNA sequences isolated from Cyathura carinata (Crustacea: Isopoda) indicate that two different species of the Digenea (Platyhelminthes: Trematoda) parasitize this isopod species for which parasitic associations have previously been unknown. Phylogenetic analysis, based on the largest data set of digenetic 18S rDNA sequences published to date, also suggests that 18S rDNA is unsuitable for the reconstruction of phylogenetic relationships of the major digenetic lineages either due to rapid radiation of these lineages or the presence of homoplasy at this level.

摘要

对从长指海蟑螂（甲壳纲：等足目）分离出的18S rDNA序列进行分析，结果表明两种不同的复殖吸虫（扁形动物门：吸虫纲）寄生于此前未知有寄生关联的这种等足目动物。基于迄今公布的最大规模复殖吸虫18S rDNA序列数据集进行的系统发育分析还表明，由于这些谱系的快速辐射或该水平上存在同塑性，18S rDNA不适用于重建主要复殖吸虫谱系的系统发育关系。
