A new strigeid digenean, Strigea meridionalis sp. n., is described from the small intestine of the savanna hawk, Buteogallus meridionalis (Latham) (Aves: Accipitridae), from Formosa Province, Argentina. This species is characterised by the absence of a neck region in the hindbody, the presence of entire testes, a copulatory bursa with a membranous fold originated from the muscular ring (Ringnapf) and by the arrangement of vitelline follicles in the forebody. Other two strigeid species collected from the savanna hawk, Strigea elliptica (Brandes, 1888) and Strigea microbursa Pearson et Dubois, 1985, are described and illustrated. Strigea microbursa is reported for the first time from the Neotropical Region and B. meridionalis represents a new host record for S. elliptica. These findings allow us to increase the knowledge of these species, adding new metric and morphological data. A key to the species of the Neotropical Strigea Abildgaard, 1790 is presented including data on their geographical distribution.
在阿根廷福尔摩沙省的热带草原鹰（Buteogallus meridionalis (Latham)，鸟纲：鹰科）的小肠中发现了一种新的艾氏科复殖吸虫，即南方艾氏吸虫（Strigea meridionalis sp. n.）。该物种的特征在于虫体后体无颈部区域、睾丸完整、具有一个由肌肉环（Ringnapf）产生的膜状褶皱的交配囊以及前体中卵黄滤泡的排列方式。还对从热带草原鹰体内采集到的另外两种艾氏科物种，即椭圆艾氏吸虫（Strigea elliptica (Brandes, 1888)）和微囊艾氏吸虫（Strigea microbursa Pearson et Dubois, 1985）进行了描述和图示。微囊艾氏吸虫首次在新热带区被报道，而热带草原鹰是椭圆艾氏吸虫的新宿主记录。这些发现使我们能够增加对这些物种的了解，并补充新的测量和形态学数据。给出了1790年新热带区艾氏属物种的检索表，包括它们的地理分布数据。
