Abstract

New evidences on the presence of Aphelocheirus aestivalis in the Iberian Peninsula, its ecology and description of two northeastern Iberian populations The waterbug Aphelocheirus aestivalis is herein recorded for the first time in Northeastern Iberian Peninsula, constituting the first citation of the family Aphelocheiridae in the region. Yet, later on in 1989, the description of three new endemic Iberian species belonging to Aphelocheirus implied the assumption that A. aestivalis was absent in the Iberian Peninsula. Here, we show strong evidences of the presence of this species by the collection of individuals in two isolated stream reaches located 36 km apart, in the two Mediterranean rivers Llobregat and Ter. The Iberian specimens studied showed slight differentiation from other European specimens in the structures of male internal genital. Photographs of the habitus of the male and female are provided. More than 25 years of study of these rivers show that Aphelocheirus sp. is confined solely to a short stretch in both rivers. Our study thus suggests that the distribution of A. aestivalis in the Iberian Peninsula should be revised and further investigated, and warns of urgent measures to improve, or at least preserve, the habitat and the hydrological conditions rivers Llobregat and Ter to protect the species.

伊比利亚半岛夏氏Aphelocheirus aestivalis存在的新证据、生态学及其对伊比利亚东北部两个种群的描述

本文首次在伊比利亚半岛东北部记录到水虫Aphelocheirus aestivalis，构成了该地区首次引用Aphelocheirus aestivalis科的文献。然而，后来在1989年，对属于Aphelocheirus的三个新的伊比利亚特有物种的描述暗示了在伊比利亚半岛不存在aestivalis的假设。在这里，我们通过在两条相距36公里的地中海河流Llobregat和Ter中收集的个体，展示了该物种存在的有力证据。研究的伊比利亚标本在男性内生殖器结构上与其他欧洲标本有轻微的差异。提供了男性和女性的习性照片。对这两条河流超过25年的研究表明，Aphelocheirus sp只局限于两条河流的一小段区域。因此，我们的研究表明，在伊比利亚半岛上，应修改和进一步调查aestivalis的分布，并警告采取紧急措施改善或至少保持栖息地和水文条件，以保护该物种。
