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]
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.
Akysis is the largest genus of catfishes of the family Akysidae.
Chaca is the only genus in the catfish family Chacidae. These fish are commonly known as squarehead catfishes, frogmouth catfishes, or angler catfishes. These unusual fish have a sedentary lifestyle and spend much of their time motionless.
Myersglanis is a genus of sisorid catfishes native to Asia.
Hemibagrus wyckii is a species of catfish of the family Bagridae. It is occasionally called the crystal-eyed catfish.
Batasio is a genus of catfish of the family Bagridae. These small fish are found in fast-flowing hillstreams throughout South and mainland Southeast Asia.
Caelatoglanis zonatus is a species of catfish of the family Erethistidae. It is the only member of the monotypic genus Caelatoglanis.
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 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.
