Gogangra is a genus of sisorid catfishes native to Asia.
G. viridescens was previously placed in the genus Nangra . In 1998, the genus was given the name Gangra, but this name was already preoccupied by the genus Gangra of lepidopterans, so Gogangra was proposed as a replacement name in 2001. [1] G. laevis was described in 2004. [1]
There are currently two recognized species in this genus: [2]
Gogangra species are distributed in the Ganges, Meghna, and Brahmaputra drainages, India and Bangladesh. G. viridescens is known from the Ganges and Brahmaputra drainages of India and Bangladesh. [3] It is also reported from the Indus drainage in Pakistan, Nepal, and Bhutan. [4] G. laevis is from the Yamuna and Meghna River drainages of the lower Brahmaputra River drainage in Bangladesh. [3] [5]
G. viridescens is found in the upper reaches of rivers. [4]
Gogangra species have a depressed head, small conical teeth in the lower jaw, the branchiostegal membranes free from isthmus, small serrations on the anterior margin of the pectoral spine (and a smooth posterior edge), no well-developed maxillary barbel membrane, the outer and inner mental barbels widely separated with the origin of inner barbels anterior to origin of outer barbels, short nasal and maxillary barbels, and palatal teeth absent. [3] Live specimens have a viridescent or silvery supraopercular mark. [3]
Gogangra species grow to about 8.0–8.5 centimetres (3.1–3.3 inches) in length. [5] [4]
Erethistidae are a family of catfishes that originate from southern Asia. It includes about 45 species.
Glyptothorax is a genus of catfishes order Siluriformes of the family Sisoridae. It is the most species-rich and widely distributed genus in the family with new species being discovered on a regular basis. These species are distributed in the Black Sea basin, northern Turkey, south and east to the Yangtze River drainage in China and south throughout Indo-China to Java, Indonesia. They are found in Asia Minor and southwards to Southeast Asia. The genus is very diverse in the Indian subcontinent. Southeast Asian species tend to have restricted distributions.
Myersglanis is a genus of sisorid catfishes native to Asia.
Caelatoglanis zonatus is a species of catfish of the family Erethistidae. It is the only member of the monotypic genus Caelatoglanis.
Ayarnangra estuarius is a species of catfish of the family Erethistidae. It is the only member of the monotypic genus Ayarnangra.
Parachiloglanis hodgarti, the torrent catfish, is a species of catfish of the family Sisoridae.
Erethistoides is a genus of South Asian river catfishes.
Erethistes is a genus of South Asian river catfishes.
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 north-eastern 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 north-eastern 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.
Sisor is a genus of catfishes native to Asia.
Gagata is a genus of sisorid catfishes native to Asia.
Nangra is a genus of sisorid catfishes native to Asia.
Pseudexostoma is a genus of fish in the family Sisoridae endemic to China. These species are restricted to the upper Salween and one upper branch of the Irrawaddy in China. P. brachysoma is known only from the middle and lower Nujiang River. P. yunnanensis is only known from the upper Dayinjiang. These rivers were once connected, but are now separated. Also, the environment and temperature of the Nujiang River became greatly different between the northern and southern areas, leading to speciation.
Conta conta, the Conta catfish, is a species of South Asian river catfish. This species grows to a length of 7.8 centimetres (3.1 in) TL.
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.
Oreoglanis heteropogon is a species of catfish in the family Sisoridae found in the Salween River drainage in western Thailand which was discovered by Vidthayanon, Saenjundaeng and H.H. Ng in 2009.
Oreoglanis majuscula is a species of catfish in the family Sisoridae, found in the Kameng River in Arunachal Pradesh state, Brahmaputra drainage, India.
