    CEPF Western Ghats Special Series: Re-description of Hypselobarbus lithopidos (Teleostei: Cyprinidae), based on its rediscovery from the Western Ghats, India, with notes on H. thomassi
    Type
    Journal Article
    Description
    In recent times, though the genus Hypselobarbus has been studied substantially, the identities of individual species remain ambiguous. Hypselobarbus lithopidos has been assessed as Data Deficient in the IUCN Red List of Threatened Species with a speculation that it could possibly be extinct as there has not been any validated record of this species since 1941 from its known range. In this work we report a population of this species from its type locality and re-describe this little known species to clear any taxonomic ambiguity that surrounds the identity of this species. We also attempt to clear the taxonomic ambiguity that surrounds the identity of the Critically Endangered H. thomassi with fresh collections from the type locality are discussed.

  • Title
    Records of the endemic and threatened catfish, Hemibagrus punctuates from the southern Western Ghats with notes on its distribution, ecology and conservation status
    Type
    Journal Article
    Description
    The Nilgiri Mystus, Hemibagrus punctatus, a rare bagrid catfish endemic to the Western Ghats, has been currently listed in the IUCN Red List, as Critically Endangered with a possibility that it could be extinct. The last validated record of H. punctatus was known to be in 1998, and several surveys since then have not been able to collect the species from its native range. In this paper, we provide information on new records of this rare catfish from the Western Ghats after a period of 14 years, and discuss its distribution, ecology and conservation. An updated conservation assessment of this species following the IUCN Red List Criteria is also provided.

  • Title
    Rediscovery of Hypselobarbus pulchellus, an endemic and threatened barb (Teleostei: Cyprinidae) of the Western Ghats, with notes on H. dobsoni and H. jerdoni
    Type
    Journal Article
    Description
    Hypselobarbus pulchellus, is a poorly known species, with very few verifiable records since its description in 1870. Many authors have considered H. pulchellus to be a synonym of either H. dobsoni or H. jerdoni. This lack of information and clarity on its identity has led to H. pulchellus being categorized as a ‘Critically Endangered’ (possibly Extinct) species in the IUCN Red List of Threatened Species. Based on the collection of H. pulchellus from its type locality, we re-describe this little known species, and clear its taxonomic ambiguity vis-à-vis H. dobsoni and H. jerdoni.
