本文报道了一个单型属Metronectes Sharp，1882，为Agabus aubei佩里斯建立的。在此将其列为Agabus Leach，1817的一个亚属，以排除A. aubei很可能使Agabus paraphylectic。支持这一假设的幼虫和成人功能进行了详细讨论。所有（L1 ‐LIII）幼虫龄A. Aubei是第一次被描述。A. Aubei是一种山地物种，栖息在水流流经的陡峭岩石上的显花受精植物垫上。栖息在这种情况下的物种被称为显栖动物群。A. Aubei在形态上适应了这种爬行和穴居的生活方式：例如，成虫的触角粗壮，游动毛减少，幼虫短小粗壮，尾须短。系统地阐述了A.奥贝讨论。它可能是一部分，或密切相关的，亚属Dichonectes的Agabus，其中的物种是rheobiotic。
The monotypic genus Metronectes Sharp, 1882 was erected for Agabus aubei Perris. It is here ranked as a subgenus of Agabus Leach, 1817, for exclusion of A. aubei very probably renders Agabus paraphylectic. Larval and adult features supporting this hypothesis are discussed in detail. All (LI‐LIII) larval instars of A. aubei are described for the first time. A. aubei is a montane species which inhabits mats of phanerogamous plants growing on steep rocks over which water flows. Species inhabiting such situations are referred to as the phanerofluicolous fauna. A. aubei shows morphological adaptations to this crawling and burrowing mode of life: e.g. stout antennae and reduction of swimming hairs in the adults, as well as short and stout larvae with short urogomphi. The systematic position of A. aubei is discussed. It is probably part of, or closely related to, the subgenus Dichonectes of Agabus the species of which are rheobiotic.
