On the other hand, the Gerromorpha contain six well-supported and/or well-diagnosed clades: Mesoveliidae, Hebridae, Hermatobatidae, Hydrometridae, Macroveliidae + Paraphrynoveliidae and Veliidae + Gerridae, five of which were already recognized by Andersen (1982).
Polhemus, 1980 and that Austrovelia caledonica Malipatil and Monteith, 1983 was the sister species to all other Mesoveliidae, thus making the Mesoveliinae a paraphyletic entity.
