Taxonomy [top]

Kingdom Phylum Class Order Family
Animalia Chordata Actinopterygii Siluriformes Sisoridae

Scientific Name: Glyptothorax ngapang Vishwanath & Linthoingambi, 2007
Taxonomic Notes: Glyptothorax ngapang was described from the Iril River, a tributary of the Chindwin River in Manipur, India (Vishwanath and Linthoingambi 2007).  This species has often been misidentified as either G. dorsalis or G. minimaculatus in museum collections and in the literature (e.g. Chu and Mo 1999).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2010
Date Assessed: 2010-04-09

Justification:
Glyptothorax ngapang was described from the Iril River, a tributary of the Chindwin River in Manipur, India. Even though there is little information on the distribution, population (and its trends), and biology of this species, data from field surveys suggests that this is an abundant species in the Irrawaddy and (to a lesser extent) the Salween river drainages. In the light of this evidence, this species is assessed as Least Concern.

Geographic Range [top]

Range Description:This species is known from the Chindwin drainage in Manipur, India.  It probably occurs in Myanmar in the Irrawaddy and Salween River drainages.  In Manipur it has been recorded from Iril River in Bamonkampu Village, Lokchao River in Moreh and Imphal River in Sekmaijin (Vishwanath and Linthoingambi 2007).
Countries occurrence:
Native:
China (Yunnan); India (Manipur); Myanmar (Myanmar (mainland))

Population [top]

Population:Although the current population and its trends are unknown for this species, current indications from field surveys are that this species is still relatively widespread and abundant.
Current Population Trend:Unknown
Additional data:
Continuing decline of mature individuals:Unknown
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species inhabits swift-flowing rivers with a substrate of sand and rocks.
Systems:Freshwater
Continuing decline in area, extent and/or quality of habitat:Unknown

Use and Trade [top]

Use and Trade: This species is caught as a food fish and is commonly encountered in the markets of Myanmar (H.H. Ng pers. comm.).

Threats [top]

Major Threat(s): The threats to this species are unknown, since there is little information on the biology of this species and therefore the impact of potential threats (especially those of an anthropogenic nature) remains unknown. The current threats to aquatic biodiversity in all of its known distribution have also not been adequately identified.

Conservation Actions [top]

Conservation Actions: More research about the population size and trends, distribution and the biology of this species is needed, as there is insufficient information available. Potential threats to this species also need to be identified.
