Taxonomy [top]

Kingdom Phylum Class Order Family
Animalia Chordata Actinopterygii Cypriniformes Balitoridae

Scientific Name: Schistura papulifera Kottelat, Harries & Proudlove, 2007
Taxonomic Notes: Kottelat et al. (2007) described the species from Synrang Pamiang cave system, Meghalaya, India.

Assessment Information [top]

Red List Category & Criteria: Critically Endangered B1ab(iii)+2ab(iii) ver 3.1
Year Published: 2010
Date Assessed: 2010-01-21
Assessor(s): Vishwanath, W.
Reviewer(s): Britz, R. & Allen, D.J.
Contributor(s): Molur, S.
Justification:
Schistura papulifera is currently known with certainty only from the Krem Synrang Pamiang cave system of less than 15 kmĀ², in the Jaintia Hills, eastern Meghalaya  The species is considered to be Critically Endangered as it is known from a single location with highly restricted extent of occurrence and area of occupancy with threats from mining and quarrying resulting in habitat loss and decline in habitat quality.

Geographic Range [top]

Range Description:Schistura papulifera is currently known with certainty only from the Krem Synrang Pamiang system, in the Jaintia Hills, eastern Meghalaya. Synrang Pamiang is an extensive system, with over 14 km of mapped cave passages and five known entrances.
Countries occurrence:
Native:
India (Meghalaya)
Additional data:
Estimated area of occupancy (AOO) - km2:0-10Continuing decline in area of occupancy (AOO):Yes
Estimated extent of occurrence (EOO) - km2:0-10

Population [top]

Population:The species is known only from two individuals, one holotype and one paratype which Kottelat et al. (2007) described. Habitat destruction might affect the population of the species.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Meghalaya experiences extremly high rainfall during May to October, but water levels remains low in winter. Schistura papulifera inhabits pools of standing water, rather than in flowing streams. It appears to be most abundant in areas where the pools are both deep and extensive. It is likely that it retreats to such areas as the onset of the dry season results in falling water levels, and that the larger pools offer the best resources in terms of food and relatively stable oxygen levels (Kottelat et al. 2007)
Systems:Freshwater
Continuing decline in area, extent and/or quality of habitat:Yes

Use and Trade [top]

Use and Trade: No use in this species is known so far.

Threats [top]

Major Threat(s): The main threat to this species is the destruction of its habitat due to limestone extraction industry near the Synrang Pamiang. Kottelat et al. (2007) suggested that the species should be moved to the Critically Endangered category in the near future.

Conservation Actions [top]

Conservation Actions: The species' known location, cave systems, are threatened by limestone quarrying.
