An inventory of aquatic and semiaquatic Heteroptera (Insecta: Hemiptera) from Iber Natural Reserve (Corrientes Province, Argentina) is presented based on data from literature and the results of 10 expeditions to the region between 2003 and 2018. Different environments were surveyed at six ranger stations: Galarza, Itat, Laguna Iber, San Ignacio, San Nicols and Yahaver. In total, 69 species of Gerromorpha (23) and Nepomorpha (46) included in 29 genera (Gerromorpha, 13; Nepomorpha, 16) and 13 families (Gerromorpha, 5; Nepomorpha, 8) were recorded, representing 73% of the aquatic and semiaquatic Heteroptera fauna known from Corrientes Province. Gerridae was the richest family with regards to genera (6), followed by Veliidae (3), Belostomatidae (3), Naucoridae (3), and Notonectidae (3). However, with regards to species, Belostomatidae was the richest family (14 species), followed by Gerridae (10), Veliidae (8), Notonectidae (7), Naucoridae (6), Nepidae (6), Corixidae (4) and Micronectidae (4). The remaining 10 species belonged to Pleidae (3), Mesoveliidae (2), Hebridae (2), Gelastocoridae (2) and Hydrometridae (1). Five species are new for Argentina: Paravelia rotundanotata (Hungerford, 1930) (Veliidae), Steinovelia vinnula (Drake, 1951) (Veliidae), Neogerris celeris (Drake Harris, 1934) (Gerridae), Ovatametra obesa Kenaga, 1942 (Gerridae) and Curicta granulosa De Carlo, 1951 (Nepidae). Three genera (Paravelia Breddin, 1898; Brachymetra Mayr, 1865; Ovatametra Kenaga, 1942) are herein first recorded from Corrientes Province. Thirteen species are first recorded from Corrientes Province, raising to 94 the number of species of aquatic and semiaquatic Heteroptera recorded from the province. Twenty-eight species and six genera (Merragata White, 1877; Paravelia; Brachymetra; Halobatopsis Bianchi, 1896; Ovatametra; Rheumatobates Bergroth, 1892) are new for the Reserve. Geographic distributions and habitat associations of all species are presented. Our study highlights the importance of this Reserve for the protection of the aquatic and semiaquatic Heteroptera fauna and the habitats upon which they rely.
伊比利亚自然保护区（阿根廷科连特斯省）半水生和水生异翅目昆虫（昆虫纲：半翅目）名录基于文献数据和 2003 年至 2018 年间 10 次该地区考察的结果编制。在 Galarza、Itat、Lagoa Iber、San Ignacio、San Nicols 和 Yahaver 六个护林站调查了不同的环境。共记录了 Gerromorpha（23 种）和 Nepomorpha（46 种）的 69 种，包括 29 属（Gerromorpha，13 种；Nepomorpha，16 种）和 13 科（Gerromorpha，5 种；Nepomorpha，8 种），占科连特斯省已知半水生和水生异翅目动物区系的 73%。Gerromorpha 科的属最为丰富（6 个），其次是 Veliidae（3 个）、Belostomatidae（3 个）、Naucoridae（3 个）和 Notonectidae（3 个）。然而，从物种数量来看，Belostomatidae 科最为丰富（14 种），其次是 Gerridae（10 种）、Veliidae（8 种）、Notonectidae（7 种）、Naucoridae（6 种）、Nepidae（6 种）、Corixidae（4 种）和 Micronectidae（4 种）。其余 10 种属于 Pleidae（3 种）、Mesoveliidae（2 种）、Hebridae（2 种）、Gelastocoridae（2 种）和 Hydrometridae（1 种）。有 5 种是阿根廷的新记录：Paravelia rotundanotata（Hungerford，1930）（Veliidae）、Steinovelia vinnula（Drake，1951）（Veliidae）、Neogerris celeris（Drake Harris，1934）（Gerridae）、Ovatametra obesa Kenaga，1942（Gerridae）和 Curicta granulosa De Carlo，1951（Nepidae）。Breddin 属（1898 年）、Brachymetra Mayr，1865 年和 Ovatametra Kenaga，1942 年这三个属是科连特斯省的首次记录。有 13 种是科连特斯省的首次记录，使该省记录的半水生和水生异翅目动物种类增加到 94 种。有 28 种和 6 个属（Merragata White，1877；Paravelia；Brachymetra；Halobatopsis Bianchi，1896；Ovatametra；Rheumatobates Bergroth，1892）是保护区的新记录。所有物种的地理分布和生境联系都有介绍。我们的研究强调了该保护区对保护半水生和水生异翅目动物区系及其所依赖的生境的重要性。
