Abstract

Prionohydrus cambyreta sp. nov. is described from the Iberá wetlands, Corrientes Province, Argentina. Diagnostic characters are described and illustrated in detail, and the new taxon is compared with the other four South American species of Prionohydrus Gómez & Miller, 2013. In external appearance, P. cambyreta is very similar to P. matogrossensis Gómez & Miller 2013, but it can be distinguished by the shape of the male genitalia. The new species represents the most southern record for Prionohydrus, extending the distributional range of the genus by about 1700 km.

摘要

新物种坎氏锯角水虻（Prionohydrus cambyreta）是在阿根廷科连特斯省的伊贝拉湿地发现并被描述的。文中详细描述并展示了该物种的鉴别特征，并将这个新分类单元与2013年戈麦斯和米勒描述的锯角水虻属（Prionohydrus）的其他四个南美物种进行了比较。从外观上看，坎氏锯角水虻与2013年发现的马托格罗索锯角水虻（Prionohydrus matogrossensis）非常相似，但可以通过雄性生殖器的形状来区分。这个新物种代表了锯角水虻属最南端的记录，使该属的分布范围向南扩展了约1700公里。
