New water strider species of Eurymetra from Madagascar (Hemiptera: Heteroptera: Gerridae)

Abstract

<jats:p>The Madagascan material of the halobatine genus Eurymetra Esaki, 1926 (Hemi­ptera: Heteroptera: Gerridae: Halobatinae), which is deposited at the Natural History Museum Vienna, is revised. A close examination of “Eurymetra madagascariensis Poisson, 1945” revealed two new species, Eurymetra santamariae sp. nov. and Eurymetra papaceki sp. nov. A definition of the newly established Eurymetra madagascariensis species group is provided as well as keys to the freshwater halobatine genera and to Eurymetra species known from Madagascar.</jats:p>

Big-eyed bugs of the Malagasy Region (Hemiptera: Heteroptera: Lygaeoidea: Geocoridae)

“…The study of the fauna of the suborder Heteroptera -the largest and most diverse group of non-holometabolous insects (Schuh & Weirauch 2020) -received increasing attention in the past years, though monographs are available for only few families and subfamilies, as reviewed by Kment et al (2016). More recently, groups such as the largest lygaeoid family, Rhyparochromidae (Zámbó et al 2019, Kondorosy et al 2020, Kondorosy & Zámbó 2021, Zámbó et al 2022, family Aradidae (Baňař & Heiss 2018a, b), selected aquatic and semi-aquatic heteropteran taxa (Zettel 2020, Zettel & Laciny 2020, and assassin bugs (family Reduviidae) (Chłond et al 2018, Weirauch 2022, Chen et al 2022) received attention.…”
