Following on from the partial review of European Magelonidae by Fiege et al. (2000), a dichotomous identification key, a table of characters and images of all nine known European magelonid species are provided. Magelona equilamellae is redescribed highlighting several features not reported originally by Harmelin. Notably the thoracic neuropodial lamellae, which are initially prechaetal but become distinctly postchaetal by chaetiger 7, an additional character allowing separation from the morphologically similar Magelona alleni. Records suggest that M. equilamellae is a Mediterranean species, more commonly occurring in shallow, transitional waters. Several new characters for Magelona filiformis are additionally highlighted as well as a number of corrections to the existing description, including the number of prostomial ridges, presence of abdominal lateral pouches, morphology of chaetiger 9, and the presence of smaller abdominal hooded hooks adjacent to lateral lamellae. The first image of M. filiformis minuta is provided, and its synonymy with M. filiformis further supported.
继菲格等人(2000年)对欧洲长手沙蚕科进行部分综述之后,提供了一个双歧式鉴定检索表、一份特征表以及所有9种已知欧洲长手沙蚕科物种的图像。重新描述了等叶长手沙蚕,突出了一些哈梅林最初未报道的特征。值得注意的是胸足神经叶,其最初在刚毛之前,但到第7刚节时明显在刚毛之后,这一额外特征有助于将其与形态相似的艾伦长手沙蚕区分开来。记录表明等叶长手沙蚕是一种地中海物种,更常见于浅水过渡水域。此外,还突出了丝状长手沙蚕的几个新特征以及对现有描述的一些修正,包括口前部嵴的数量、腹部侧袋的存在、第9刚节的形态以及与侧叶相邻的较小腹部带帽钩的存在。提供了微小丝状长手沙蚕的首张图像,并进一步支持了它与丝状长手沙蚕的同义关系。
