Gerromorpha genera

Halobates, colloquially the sea skaters or ocean striders, are an insect genus with over 40 species of water striders. Most Halobates species are coastal and typically found in sheltered, coastal marine habitats (a habitat where a few other genera of water striders also live), but five live on the surface of the open ocean and only occur near the coast when storms blow them ashore. These are the only known truly oceanic, offshore insects. They are found in tropical and subtropical marine habitats around the world, with a single species recorded in rivers a few kilometers upstream from the ocea

Paraphrynovelia is a genus of bugs with just two species in southern Africa. Together they are considered by some to form the family Paraphrynoveliidae, although some suggest that they should be treated as members of the Macroveliidae. Unlike other Gerromorpha that are found on the surface of water, Paraphrynovelia brincki specimens were found on wet walls covered in moss or in leaf litter on the forest floor. The family status was suggested in 1978.
