Cypriniformes is an order of ray-finned fish, which includes many families and genera of cyprinid fish, such as barbs, gobies, loaches, botias, and minnows. Cypriniformes is an "order-within-an-order", placed under the superorder Ostariophysi—which is also made up of cyprinid, ostariophysin fishes. The order contains 11–12 families, over 400 genera, and more than 4,250 named species; new species are regularly described, and new genera are recognized frequently. Cyprinids are most diverse in South and Southeast Asia, but are entirely absent from Australia and South America. At 112 years old, the longest-lived cypriniform fish documented is the bigmouth buffalo.
Cobitidae, also known as the true loaches, is a family of Old World freshwater fish. They occur throughout Eurasia and in Morocco, and inhabit riverine ecosystems. Today, most "loaches" are placed in other families. The family includes about 260 described species. New species are being described regularly.

Homaloptera is a genus of ray-finned fish in the family Balitoridae.
Loaches are ray-finned fish of the suborder Cobitoidei. They are freshwater, benthic (bottom-dwelling) fish found in rivers and creeks throughout Eurasia and northern Africa. Loaches are among the most diverse groups of fish; the 1249 known species of Cobitoidei comprise about 107 genera divided among 9 families.
Sewellia is a genus of fish in the family Gastromyzontidae. They are commonly called hillstream loaches and are found in Laos and Vietnam. According to Roberts (1998) a possible defining characteristic of the genus Sewellia is their posterior pelvic valve is highly complex and different from other rheophilic loaches, their posterior pelvic valve involves the overlapping of the second to last ventrally exposed rays. Adapted to high velocity streams, Sewellia have depressed body shapes that are laterally expanded, thus increasing their hydrodynamical properties and allowing them to better stay attached to rocks in swift current. Sewellia also have paired fins with a single simple ray and numerous branched rays allowing them to grip rocks in swift current.
Balitoropsis also known as the lizard loaches is a genus of hillstream loaches native to eastern Asia.
The Gastromyzontidae are a family of loaches native to China and Southeast Asia, where typically found in streams and rivers with a fast current. The family includes about 137 species in eighteen genera. This family was resurrected by M. Kottelat in his review and revision of the loaches in 2012. They are commonly called hillstream loaches.
Homalopteroides is a genus of hillstream loaches native to Southeast Asia.
