Amphizoa sinica is a species of beetle in the Amphizoidae family. The length of its body is between 11 and 13.5 millimeters. Its metasternal process is depressed, with the lateral margin raised. It lives in the northeastern province of Jilin in China and in North Korea. [1]
Amphizoa is a genus of aquatic beetles in the suborder Adephaga, placed in its own monogeneric family, Amphizoidae. There are five known species of Amphizoa, three in western North America and two in eastern palearctic. They are sometimes referred to by the common name troutstream beetles.
Hydraenidae is a family of very small aquatic beetles, sometimes called "minute moss beetles", with a worldwide distribution. These beetles are generally 1–3 mm in length with clubbed antennae. They do not swim well and are generally found crawling in marginal vegetation. Most are phytophagous but a few saprophagous and predatory species are known.
Hygrobia is a genus of aquatic beetles native to Europe, North Africa, China and Australia. It is the only genus in the family Hygrobiidae, also known as the Paelobiidae. These are known commonly as squeak beetles or screech-beetles.
Copelatus sociennus is a species of diving beetle. It is part of the subfamily Copelatinae in the family Dytiscidae. It was described by J. Balfour-Browne in 1952. The species can be found on Coloane and in Seac Pai Van. It feeds on Nelumbo nucifera.
Zigetangcuo Lake is a crenogenic meromictic lake in the North Tibetan Plateau. It is located in Nagqu Prefecture, north of Dongqiao. It has an area of 187 square kilometers at an altitude of 4560 meters. It is the meromictic lake with the highest known altitude.
Ancyronyx, commonly known as spider water beetles or spider riffle beetles, is a genus of aquatic riffle beetles from North America, South Asia, China, and Southeast Asia. They are small beetles with extremely long legs ending in strong claws. Both the adults and the larvae are found underwater in the shallow riffles of streams and rivers, clinging to rocks or submerged wood. They feed on algae and decaying wood tissue.

Its elytra are most notable for lacking a carina on the fifth interval. The pronotum has a lateral margin without lateral bead. The species is only known from the province Sichuan of in especially in China.

Aquatica hydrophila is a species of firefly found in Taiwan. Described in 2003, it was formerly placed in the genus Luciola. The larvae are aquatic and live in ditches and small streams.
Aquatica lateralis, known as "heike-botaru" (ヘイケボタル) in Japanese, is a species of firefly found in Russia, Japan and Korea. It was formerly placed in the genus Luciola. The larvae are aquatic and live in rice paddies.
Luciola substriata is a species of firefly found in India, Myanmar, China and Taiwan. The larvae are aquatic and can swim, living in marshes, paddies, lakes and ponds.

Epimetopidae is a family of semi-aquatic beetles found on the edges of streams and shallow freshwater ponds. These beetles are shorter than half a centimeter long and have a pronotum with a central projection forming a shelf above the head. On the underside of the abdomen only four sternites are visible. There are less than a hundred species in three genera, Epimetopus which is restricted to the New World, mostly Neotropical, Eupotemus with two Afrotropical species and Eumetopus with some Oriental species. Females carry their eggcases on the underside of the abdomen.
Aspidytidae is a family of aquatic beetles of the suborder Adephaga, described in 2002 from specimens in South Africa and China. There are only two known species in the family and these were originally described in the genus Aspidytes, but later the new genus Sinaspidytes was erected for the species found in China. The family can also be referred to by its trivial name cliff water beetles.
