Gerromorpha
The Gerromorpha comprise an infraorder of insects in the "true bug" order (biology), order Hemiptera. These "typical" bugs (suborder Heteroptera) are commonly called semiaquatic bugs or shore-inhabiting bugs. The Ochteroidea (infraorder Nepomorpha are also found in shore habitat, while the Gerromorpha are actually most often encountered running around on the water surface, being kept from sinking by surface tension and their hydrophobic, water-repellent legs. Well-known members of the Gerromorpha are the namesake Gerridae (water striders). Systematics The eight family (biology), family families usually recognized are arranged in four Superfamily (zoology), superfamilies. The two small or monotypic ones of these are basal (evolution), basal lineages; the two larger ones form a more advanced clade. The phylogenetic sequence of superfamilies and families of the Gerromorpha is:ToL (1995) ;Mesovelioidea – water treaders * Madeoveliidae (sometimes included in Mesoveliidae) * Mesov ...

Paraphrynoveliidae
''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 The Gerromorpha comprise an infraorder of insects in the "true bug" order (biology), order Hemiptera. These "typical" bugs (suborder Heteroptera) are commonly called semiaquatic bugs or shore-inhabiting bugs. The Ochteroidea (infraorder Nepomorph ... 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. The species in the genus are ''Paraphrynovelia brincki'' and ''P. slateri'' . Both have been described on the basis of apterous adults. A molecular study making use of ''P. brincki'' suggests that they are a sister group of the Macroveliidae. References {{Taxonbar, from ...

Hebridae
Velvet water bugs are members of the family Hebridae. They are semiaquatic insects that live among moss or ponds with an abundance of vegetation, in which they prey on small arthropods. Velvet water bugs are the smallest of the Gerromorpha, and have an appearance of tiny veliids. Hebrids sometimes move across water surfaces, but walk or run rather than skate or scull on the surface. Description Hebrids are small, ranging from lengths of 1.3 to 3.7 mm. They have a characteristic layer of short, dense hairs that cover their entire bodies, except on their abdomens and appendages, from which they derive the common name "velvet water bug". They have tarsi in two segments, with their hing legs shorter than their bodies. Unlike the Veliidae and Mesoveliidae, they are known only as winged forms. These wings, however, may be well-developed to short or lacking. The wing's membrane, when it is present at all, lacks any distinct veins that are common of shore bugs Saldidae. They are ty ...

Gerridae
The Gerridae are a family of insects in the order Hemiptera, commonly known as water striders, water skeeters, water scooters, water bugs, pond skaters, water skippers, water gliders, water skimmers or puddle flies. They are true bugs of the suborder Heteroptera and have mouthparts evolved for piercing and sucking. A distinguishing feature is the ability to move on top of the water's surface, making them pleuston (surface-living) animals. They can be found on most ponds, rivers or lakes, and over 1,700 species of gerrids have been described, 10% of them being marine. While 90% of gerrids are freshwater bugs, the oceanic '' Halobates'' makes the family quite exceptional among insects. The genus ''Halobates'' was first heavily studied between 1822 and 1883 when Francis Buchanan White collected several different species during the Challenger Expedition. Around this time, Eschscholtz discovered three species of the Gerridae, bringing attention to the species, though little of ...

Heteroptera
The Heteroptera are a group of about 40,000 species of insects in the order Hemiptera. They are sometimes called "true bugs", though that name more commonly refers to the Hemiptera as a whole. "Typical bugs" might be used as a more unequivocal alternative, since the heteropterans are most consistently and universally termed "bugs" among the Hemiptera. "Heteroptera" is Greek for "different wings": most species have forewings with both membranous and hardened portions (called hemelytra); members of the primitive sub-group Enicocephalomorpha have completely membranous wings. The name "Heteroptera" is used in two very different ways in modern classifications. In Linnean nomenclature, it commonly appears as a suborder within the order Hemiptera, where it can be paraphyletic or monophyletic depending on its delimitation. In phylogenetic nomenclature, it is used as an unranked clade within the Prosorrhyncha clade, which in turn is in the Hemiptera clade. This results from the real ...

Madeoveliidae
Water treaders, the superfamily Mesovelioidea, are insects in the order Hemiptera, the true bugs. They are semiaquatic insects that live in moist and wet habitat and on wet plant matter in several types of aquatic habitat.Yang, C. M. and D. H. Murphy. (2011)Guide to the aquatic Heteroptera of Singapore and peninsular Malaysia. 6. Mesoveliidae, with description of a new ''Nereivelia'' species from Singapore.''Raffles Bulletin of Zoology'' 59, 53-60. These insects are no more than 3.5 mm long. They have elongated heads, long antennae, and large eyes, with the exception of ''Cryptovelia'' species, which have vestigial eyes. Females are larger than the males of their species and have well-developed ovipositors. The type genus, '' Mesovelia'', contains about 27 species, many of which are common and widespread.Andersen, N. M. and D. A. Polhemus. (2003)A new genus of terrestrial Mesovellidae from the Seychelles (Hemiptera: Gerromorpha).''Journal of the New York Entomological Soc ...

Hydrometridae
Hydrometridae is a family of aquatic insect, semiaquatic insects, known as ''marsh treaders'' or ''water measurers''. They have a characteristic elongated head and body which makes them resemble a yardstick for measuring the water surface. Appearance Hydrometrid bugs are of a greyish or pale brown colour, and relatively large amongst Gerromorpha at around 8 mm, although some can exceed 15 mm. Their body and arthropod leg, legs are long and slender, to the point where they resemble tiny phasmatodeans. The family is mostly wingless, but insect wing, winged forms do occur. The head is long as well, usually more so than the body. Their eyes are located a little behind the middle of the head and tend to bulge. Their antenna (biology), antennae, positioned at the end of its head are four-segmented and their tarsi three-segmented . Habitat and ecology Marsh treaders are fairly common and have been found throughout the world. The greatest diversity, however, is found ...
