  • Title
    Gentiana saginoides Burkill (Magnoliopsida: Gentianales: Gentianaceae) rediscovered from Sunderdhunga Valley in Uttarakhand 155 years after description: notes on its population status
    Type
    Journal Article
    Description
    Gentiana saginoides Burkill (Gentianaceae) was described by Burkill in 1906 based on a collection from Sunderdhunga, Uttarakhand by T. Anderson in 1857. The species was not collected after its type collection despite attempts by several workers in the past. A field survey in and around the type locality was conducted in June 2012 and the species was re-discovered after a lapse of 155 years since its type collection. The species is tentatively categorised as ‘Critically Endangered’ based on field observations. A full description and diagrams of the species are provided here based on new specimens collected.

  • Title
    The reassessment of the threatened status of the Indian endemic Kolar Leaf-nosed Bat Hipposideros hypophyllus Kock & Bhat, 1994 (Mammalia: Chiroptera: Hipposideridae)
    Type
    Journal Article
    Description
    The Kolar Leaf-nosed Bat Hipposideros hypophyllus Kock & Bhat, 1994, endemic to Kolar District, Karnataka, India was listed as ‘Endangered’ in the IUCN Red List of Threatened Species due to its restricted distribution and continuing decline in the quality of its habitat. The species has not been sighted or collected since its initial collection in the years 1983 and 1985 wherein eight individuals were collected from Therahalli and 41 individuals were collected from Hanumanhalli, respectively. Based on recent observations and collections from the type locality, we provide information about its distribution, threats, phylogenetic position and conservation status. We also provide an updated conservation assessment of this species following the IUCN Red List categories.

  • Title
    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
    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.
