Abstract

Abstract We discovered a new species of the genus Hydaticus Leach, 1817, subgenus Prodaticus Sharp, 1882 (Coleoptera: Dytiscidae) in the unidentified material of the Muséum National d´Histoire Naturelle, Paris. The type specimens were collected near Kourou in French Guiana and are here described as Hydaticus (Prodaticus) kourouensis sp. n. The new species is morphologically similar to the Peruvian H. panguana Megna, Balke, Apenborn, and Hendrich, 2019 and H. hauthi Hendrich and Balke, 2020, but differs by its almost complete black ventral surface, the broadly oval habitus, and the flattened, slightly enlarged elytra. Furthermore, H. kourouensis sp. n. is well characterised by the shape of its median lobe. http://www.zoobank.org/urn:lsid:zoobank.org:pub:E0841C37-DB18-45E3-80B8-2981E63CCCA2

法属圭亚那一种新的潜水甲虫（鞘翅目：潜甲科）

摘要我们在巴黎国家自然历史博物馆的未经鉴定的材料中发现了一个新种，即Hydraticus Leach，1817，Prodaticus Sharp亚属，1882（鞘翅目：Dytiscidae）。这些模式标本是在法属圭亚那的库鲁附近采集的，在这里被描述为Hydaticus（Prodaticus）kourouensis sp.n。新物种在形态上与秘鲁的H.panguana Megna、Balke、Apenborn和Hendrich，2019和H.hauthi Hendrich和Balke，2020相似，但不同之处在于其几乎完全的黑色腹面、宽椭圆形的栖息地和扁平的，稍增大的鞘翅。此外，H.kourouensis sp.n的中叶形是很好的特征。http://www.zoobank.org/urn:lsid:zoobank.org:pub:E0841C37-DB18-45E3-80B8-2981E63CCCA2

期刊介绍： Aquatic Insects is an international journal publishing original research on the systematics, biology, and ecology of aquatic and semi-aquatic insects. The subject of the research is aquatic and semi-aquatic insects, comprising taxa of four primary orders, the Ephemeroptera, Odonata, Plecoptera, and Trichoptera but also aquatic and semi-aquatic families of Hemiptera, Coleoptera, and Diptera, as well as specific representatives of Hymenoptera , Lepidoptera, Mecoptera, Megaloptera , and Neuroptera that occur in lotic and lentic habitats during part of their life cycle. Studies on other aquatic Hexapoda (i.e., Collembola) will be only accepted if space permits. Papers on other aquatic Arthropoda (e.g., Crustacea) will not be considered, except for those closely related to aquatic and semi-aquatic insects (e.g., water mites as insect parasites). The topic of the research may include a wide range of biological fields. Taxonomic revisions and descriptions of individual species will be accepted especially if additional information is included on habitat preferences, species co-existing, behavior, phenology, collecting methods, etc., that are of general interest to an international readership. Descriptions based on single specimens are discouraged. Detailed studies on morphology, physiology, behavior, and phenology of aquatic insects in all stadia of their life cycle are welcome as well as the papers with molecular and phylogenetic analyses, especially if they discuss evolutionary processes of the biological, ecological, and faunistic formation of the group.
