摘要

Platygerris White由真正的虫子组成，它们栖息在中等至快速流动的淡水栖息地的水面上。该属与Cylindrostehus Mayr和Potamobates Champion（Gerridae：Cylindrosthinae）的不同之处在于，它有一个短而扁平的身体；下颌和上颌钢板融合；气味器的脐、侧槽和侧蒸发室不明显。在本文中，我们重新命名了Platygerris，描述了来自哥伦比亚的两个新种，并重新命名了P.asymmetricus Hungeford、P.caeruleus Champion和P.depressus White。此外，我们还提供了该属物种的最新识别密钥。首次基于电子显微镜对该属的表皮结构进行了描述。

Revision of the genus Platygerris White, 1883 (Hemiptera: Heteroptera: Gerridae), with descriptions of two new species from Colombia

Platygerris White comprises true bugs that inhabit the surface of water in moderate to fast-flowing freshwater habitats. This genus differs from Cylindrostethus Mayr and Potamobates Champion (Gerridae: Cylindrostethinae) by having a short and flattened body; the mandibular and maxillary plates fused; and the omphalium, lateral groove, and lateral evaporatorium of the scent apparatus inconspicuous. In this paper, we redescribe Platygerris, describe two new species from Colombia, and redescribe P. asymmetricus Hungerford, P. caeruleus Champion and P. depressus White. In addition, we present an updated identification key to the species of the genus. For the first time, the cuticular structure is described for the genus based on electron microscopy.

期刊介绍： Insect Systematics & Evolution (ISE) publishes original papers on all aspects of systematic entomology and the evolutionary history of both extant and extinct insects and related groups. Priority is given to taxonomic revisions and phylogenetic studies employing morphological and molecular data. ISE also welcomes reviews and syntheses that can appeal to a wide community of systematic entomologists. Single species descriptions, regional checklists, and phylogenetic studies based on few taxa or single molecular markers will generally not be accepted.
