Perittopus breddini is an Indonesian species of riffle bug and the designated type species of genus Perittopus . [2] [3]
Perittopus breddini is confined to Bali and Central and East Java, [1] [4] where it is found on mountains at altitudes between 730 and 1550 m above sea level. [1]
In 2001, Perittopus specimens formerly identified as belonging to respectively P. breddini or P. vicarians in Malaysia, Thailand and China were described as a new species: P. asiaticus . [1] [4]
Females larger than males; winged ("macropterous") specimens larger than wingless ("apterous") specimens of the same sex. [1] Size ranges from 3.2 mm to 4.0 mm. [1] Wingless specimens resemble those of Perittopus crinalis , but can be separated in females by the shape of the black mark on the pronotum (heart-shaped on P. breddini and indistinct on P. crinalis) and in males by the genital characteristics.

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. Consistent with the classification of the Gerridae as true bugs, gerrids have mouthparts evolved for piercing and sucking, and distinguish themselves by having the unusual ability to walk on water, making them pleuston (surface-living) animals. They are anatomically built to transfer their weight to be able to run on top of the water's surface. As a result, one could likely find water striders present in any pond, river, or lake. Over 1,700 species of gerrids have been described, 10% of them being marine.
Acanthosomatidae is a family of Hemiptera, commonly named "shield bugs" or "stink bugs". Kumar in his 1974 world revision recognized 47 genera; now this number is 55 genera, with about 200 species, and it is one of the least diverse families within Pentatomoidea. The Acanthosomatidae species are found throughout the world, being most abundant in high-latitude temperate regions and in subtropical regions at high altitudes.
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.
Cymatopus is a genus of flies in the family Dolichopodidae. Members of the genus are found on rocky coasts of the Indo-West Pacific.
Emesopsis is a genus of tropical bugs (Heteroptera) from the family Reduviidae. There are at least 22 described species, of which one, E. nubila, also occurs in southern Europe.
Perittopus is a genus of riffle bug, and the sole genus of subfamily Perittopinae. Its species occur from southern India east to Indonesia and north to China in mountain stream habitats. Visually, the red or orange to reddish colour of Perittopus spp. separates them from other members of the Veliidae.
Perittopus asiaticus is a species of riffle bug from Malaysia, China, and Thailand.
Perittopus crinalis is a species of riffle bug first described in 2013 by Zhen Ye, Pingping Chen and Wenjun Bu. It is recorded from Yunnan Province, China.
Perittopus falciformis is a species of riffle bug from China, first described in 2013 by Zhen Ye, Pingping Chen and Wenjun Bu, based on apterous specimens collected in Yunnan Province at an altitude of 1500 m. Winged specimens of either sex are thus far unknown.
Perittopus yunnanensis is a species of riffle bug first described in 2013 by Zhen Ye, Pingping Chen and Wenjun Bu. It is recorded from Yunnan Province, China, for which it is named.
Perittopus zhengi is a species of riffle bug from Thailand. It was described in 2013 by Zhen Ye, Pingping Chen and Wenjun Bu, and is named after Professor Leyi Zheng. Its authors placed it to the “eastern species group” within genus Perittopus.
Tytthus is a genus of insects in family Miridae, the plant bugs. They are carnivorous, feeding upon the eggs of various planthoppers in the family Delphacidae, and thus are important in the biological control of pests. The genus is distributed throughout the Holarctic of the Northern Hemisphere, but species are also found in the tropics, in China, South America, Australia, and the Indo-Pacific.
Ngirhaphium is a genus of flies in the family Dolichopodidae. It includes six species known from mangroves in Southeast Asia. Ngirhaphium closely resembles the genus Rhaphium and was originally placed in the subfamily Rhaphiinae, though several molecular phylogenetic analyses were unable to resolve its phylogenetic position. The genus is named after Peter Kee Lin Ng, a professor at the National University of Singapore; the genus name combines the family name "Ng" and the generic name Rhaphium.
Aquarius is a genus of water striders found predominantly in 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 12–17 mm (0.47–0.67 in) long and males roughly 10–30% smaller, depending on the exact species. An outlier is A. elongatus where both sexes typically are about 24 mm (0.94 in), roughly the same as certain Cylindrostethus, and second only to Gigantometra gigas.
Buenoa is a genus of backswimmer. It was created by George Willis Kirkaldy in 1904 to include all species of Anisops from the Western Hemisphere with a two-segmented front tarsus in males, reserving the latter genus for Eastern Hemisphere species with a one-segmented front tarsus in males. It contains 69 described species.
Micronectidae is a family of water boatmen often referred to as pygmy water boatmen. They were originally classified as a subfamily under Corixidae but were raised to family level by Nieser (2002).
Microvelia buenoi is a species of smaller water strider in the family Veliidae. It is found in Europe & Northern Asia and North America.
Phoreticovelia disparata, also called the Zeus bug, is a species of semi-aquatic bug from the family Veliidae with a unique form of sexual dimorphism. It is endemic to Australia (Queensland).
Hermatobates is a genus of wingless marine bugs placed as the sole genus in the family Hermatobatidae that are sometimes known as coral-treaders. They are quite rare and known only from coral reefs in the Indo-Pacific region. During low tide, they move over the water surface not unlike the more familiar water-striders around coral atolls and reefs and stay submerged in reef crevices during high tide.
Microvelia macgregori is a species of true bug in the family Veliidae. It is semi-aquatic, living on the surface of water in freshwater habitats in New Zealand.
