Nangra is a genus of sisorid catfishes native to Asia.
There are currently five recognized species in this genus: [1]
Nangra species are distributed in the Indus, Ganges, Meghna, and Bramhputra drainages in Pakistan, India, Bangladesh, and Nepal. N. assamensis inhabits the Ganges and Brahmaputra drainages in India. N. bucculenta originates from the Ganges drainage in Bangladesh. N. nangra is known from the Indus, Ganges and Bramhputra drainages in Pakistan, India, Bangladesh and Nepal. N. ornata lives in the Meghna drainage in Bangladesh. N. robusta is from the Indus drainage in Pakistan. [2]
Nangra is distinguished from all sisorids by having maxillary barbels that extend beyond the base of the pectoral fin (vs. extending no further than the pectoral-fin base), by having very long nasal barbels in which the barbel length is much greater than the eye diameter and often as long as the head (vs. length less than the eye diameter), and by having palatal teeth. [2] Nangra species have a depressed head, dorsolateral eyes, an elongated snout, small conical teeth in the lower jaw, branchiostegal membranes free from the isthmus, no serrations on anterior margin of pectoral spine (but serrate posteriorly), and a well-developed maxillary barbel membrane. [2]
N. bucculenta grows to about 3.4 centimetres (1.3 in) SL. [3] N. nangra grows to about 5.5 cm (2.2 in) TL. [4] N. ornata grows to about 3.7 cm (1.5 in) SL. [5] N. robusta grows to about 10.0 cm (3.9 in) SL. [6]
Myersglanis is a genus of sisorid catfishes native to Asia.

Pyxiloricaria menezesi is the only species of the monotypic genus Pyxiloricaria, a genus of the family Loricariidae of catfish.
Pseudecheneis is a genus of sisorid catfishes native to Asia.
Bagarius is an Asian genus of catfishes of the family Sisoridae. It includes five to six extant species and potentially one extinct fossil species, B. gigas.
Exostoma is a genus of sisorid catfishes native to Asia. These species are distributed in the Brahmaputra drainage of northeast India, and east and south to the Salween drainages in Burma. E. berdmorei is found in the Sittang and Salween drainages in Burma. E. labiatum is known from the Brahmaputra drainage in northeast India, but has also been recorded in the Salween drainage in Burma, the Ayeyarwady drainage in China, and the Brahmaputra drainage in Tibet and Burma. E. stuarti is from the Ayeyarwady River of Burma and India; however, it has not been collected since its original discovery. E. labiatum is found in mountain rapids.
Glyptosternon is a genus of sisorid catfishes native to Asia.
Gogangra is a genus of sisorid catfishes native to Asia.
Sisor is a genus of catfishes native to Asia.
Gagata is a genus of sisorid catfishes native to Asia.

Paraplotosus is a genus of catfishes native to Australasia and South-east Asia.
The Somalia catfish is a species of catfish in the family Bagridae. The Somalia catfish is native to the Jubba River in Somalia.
Hoplomyzon is a genus of banjo catfishes that are native to tropical South America.
Zaireichthys mandevillei is a species of loach catfish found in the Central African Republic and the Democratic Republic of the Congo where it is found in the Congo River Basin. It grows to a length of 2.6 cm and has a broad, black collar just behind the head and a spotted colour pattern. The barbels are attenuate, with the maxillary barbels extending posteriorly to middle to end of the pectoral fin spine and the caudal peduncle is slender. The humeral process of the pectoral girdle is short and without denticulations. The caudal fin is deeply forked, with the upper lobe much shorter and smaller than the lower lobe; also, the fin rays in lower lobe noticeable thicker than those in upper lobe.
Erethistoides infuscatus is a species of South Asian river catfish native to India and Bangladesh where it is found in the drainages of the Brahmaputra and Meghna Rivers. This species grows to a length of 4.5 centimetres (1.8 in) SL.
Synodontis acanthoperca, known as the scissortail synodontis, is a species of upside-down catfish native to Gabon where it occurs in the Ogowe River. It was first described by John Patrick Friel & Thomas R. Vigliotta in 2006, based upon a holotype discovered in the Ogooué River in Gabon, at and below the Rapids of Massoukou. The specific name "acanthoperca" comes from the Latinized combination of the Greek word acantha, meaning "thorn", and the Latin opercul, meaning cover or lid, which refers to the pronounced spines that develop on the operculum of mature males.
Gagata cenia is a species of sisorid catfish found in the Ganges Delta and the Indus River. It has also been reported as occurring in Thailand and Burma. This species grows to a length of 15 centimetres (5.9 in) SL.
Gagata youssoufi is a species of sisorid catfish native to India and Bangladesh. This species grows to a length of 5 centimetres (2.0 in) SL.
Gogangra laevis is a species of sisorid catfish found in Bangladesh where it occurs in the Jamuna and Meghna River drainages. This species grows to a length of 8 centimetres (3.1 in) SL.
