Aquarius (genus)
Aquarius is a genus of water striders from the Northern Hemisphere. Formerly a subgenus, Aquarius was elevated to generic rank in 1990 on the basis of phylogenetic analysis. These are among the world's largest water striders, with females averaging long and males roughly 10–30% smaller, depending on the exact species. An outlier is A. elongatus where both sexes typically are about, roughly the same as certain Cylindrostethus, and second only to Gigantometra gigas.Species within this genus include:
- Aquarius cinereus
- Aquarius conformis
- Aquarius elongates
- Aquarius najas
- Aquarius paludum
- Aquarius remigis
