Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA ACTINOPTERYGII SILURIFORMES ERETHISTIDAE

Scientific Name: Pseudolaguvia tenebricosa
Species Authority: Britz & Ferraris, 2003
Taxonomic Notes: Pseudolaguvia tenebricosa was described from the Pathe Chaung in the Sittang River drainage in southern Myanmar (Britz and Ferraris 2003).  However, the non-type material from the Irrawaddy River drainage mentioned in the original description of this species may not be conspecific with the type material from the Sittang River drainage. There is currently insufficient material of the former to verify if this is the case.

Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2010
Date Assessed: 2009-12-03
Assessor(s): Ng, H.H.
Reviewer(s): Rema Devi, K.R., Arunachalam, M., Vishwanath, W., Dahanukar, N., Daniel, B.A. & Molur, S.
Contributor(s): Molur, S.
Justification:
There is insufficient information regarding the distribution of Pseudolaguvia tenebricosa, since it has only been collected from two widely separate localities. Information about its biology and potential threats facing this species is also lacking. Furthermore, whilst the species may be present in basins between the two known localities, the conspecificity of the populations from the Irrawaddy and Sittaung River drainages requires further study. Given the lack of knowledge regarding the distribution, biology and the threats facing this species, as well as the taxonomic uncertainty surrounding the two known populations, it is assessed as Data Deficient.

Geographic Range [top]

Range Description: This species is known only from two localities in the Sittaung and Irrawaddy River drainages respectively. The type locality (Pathe Chaung) is a left bank tributary of the Sittang River in southern Myanmar (Britz and Ferraris 2003), while the other locality in which it has been recorded lies in the middle Irrawaddy River drainage in northern Myanmar.

Population [top]

Population: There is no information on the population size and trend of this species, since it is only known from 17 specimens.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: The type locality (Pathe Chaung) is a small hill stream, with fast running, clear water, a sandy bottom and numerous rocks and boulders. Aquatic vegetation was absent. Water temperature was 24°C, with a pH of 8.5 and a conductivity of 70 μS (Britz and Ferraris 2003).
Systems: Freshwater

Use and Trade [top]

Use and Trade: This species is apparently not utilized either as a food or an aquarium fish.

Threats [top]

Major Threat(s): The threats to this species are unknown, since there is no 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 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.  Furthermore, the taxonomic status of the material from the Irrawaddy River drainage needs to be further investigated and its conspecificity with the type material from the Sittang River drainage needs to be verified.
