    Distribution, threats and conservation status of the Wayanad Mahseer, Neolissochilus wynaadensis (Day, 1873) (Teleostei: Cyprinidae): an endemic large barb of the Western Ghats, India
    Type
    Journal Article
    Description
    The Wayanad Mahseer Neolissochilus wynaadensis (Day, 1873) is an endemic cyprinid fish that occurs in the upland streams and rivers of the southern region of the Western Ghats. This species has been listed as Critically Endangered on the IUCN Red List of Threatened Species due to its restricted distribution and heavy declines in populations. Like many large cyprinids of the Western Ghats, N. wynaadensis is poorly known and documented, with very few verified records and voucher specimens. Based on specimens recently collected from Wayanad, Kerala, the type locality, as well as two additional locations in the Kodagu District of Karnataka; we provide information on the current distribution, phylogenetic position, threats and conservation. An updated conservation assessment of this species following the IUCN Red List categories and criteria is also provided.

  • Title
    Pethia lutea, a new species of barb (Teleostei: Cyprinidae) and new records of P. punctata from northern Western Ghats of India
    Type
    Journal Article
    Description
    A new species of barb Pethia lutea is described from the Kundalika River in the northern part of the Western Ghats. The new species can be distinguished from its congeners in India based on a combination of characters including a distinct humped nape, absence of barbels, complete lateral line, lips thick, lateral fold on snout, 19-22 lateral line scales, 8 predorsal scales, 9-10 prepelvic scales, 14-15 preanal scales, 4-4.5 transverse scale rows between lateral line and dorsal fin origin, 2.5-3 transverse scale rows between lateral line and pelvic fin base, 6-9 pair of serrae on the distal half of the dorsal fin spine, 13-15 branched pectoral fin rays, 7 branched pelvic fin rays, 4+26 total vertebrae, 4+13 abdominal and 13 caudal vertebrae, body with one vertical humeral and one caudal blotch and dorsal fin without any bands or blotches. Additionally, we provide new records of Pethia punctata from the rivers of Maharashtra State along with a description of its osteology.

  • Title
    Balitora jalpalli, a new species of stone loach (Teleostei: Cypriniformes: Balitoridae) from Silent Valley, southern Western Ghats, India
    Type
    Journal Article
    Description
    TA new species of stone loach (Cypriniformes: Balitoridae), Balitora jalpalli, is described from Kunthi tributary of Bharatapuzha River located inside Silent Valley National Park in the southern Western Ghats of Kerala, India. It can be distinguished from known Indian species of Balitora by five major characters: head length, caudal peduncle depth, maximum head width and difference in number and pattern of bands on the dorsal side. The new species is distinct in having two unbranched and 8-9 branched ventral fin rays, nine unbranched and 10-11 branched pectoral fin rays and 66 lateral line scales, a caudal peduncle length to depth ratio of 2.3-2.7, anal fin to anus distance 3.3-4.7 % SL, least depth of caudal peduncle 6.3-6.7 % SL, length of caudal peduncle 15.4-17.2 % SL, length of upper caudal lobe 22.1-22.8 % SL, maximum head width 67.9-74.1 % HL, eye diameter 12.1-14.2 % HL, and gape 31.3-31.5 % HL.

    CEPF Western Ghats Special Series : New records of the Endangered balitorid loach, Travancoria elongate Pethiyagoda & Kottelat 1994, from the Kerala part of the Western Ghats, India
    Type
    Journal Article
    Description
    Travancoria elongata is a rare balitorid loach endemic to the Kerala part of the Western Ghats, where it was till date known to occur in two locations, one each in the Chalakudy and Periyar River. The species was listed in the IUCN Red List as Endangered as a result of its restricted distribution, and continuing decline in the quality of habitats in its range. Here we present new records of this species from three locations (Mlappara, Thanikkudy and Mankulam) in the Periyar River. Although Mlappara and Thanikkudy are located within the highly protected Periyar Tiger Reserve, the third site (Mankulam) does not have any legal protection, and is subjected to threats such as agro-based pollution and proliferation of exotic species.

  • Title
    Sahyadria, a new genus of barbs (Teleostei: Cyprinidae) from Western Ghats of India
    Type
    Journal Article
    Description
    Redline Torpedo Barbs (Teleostei: Cyprinidae), comprising of two species, Puntius denisonii and P. chalakkudiensis, and six evolutionarily distinct lineages are endemic to the streams of the Western Ghats freshwater ecoregion in peninsular India. Based on molecular and osteological evidence, we demonstrate that these barbs comprise a distinct genus, for which we propose the name Sahyadria.

  • Title
    Distribution, threats and conservation status of Hypselobarbus thomassi (Day, 1874), a poorly known cyprinid fish of the Western Ghats freshwater ecoregion
    Type
    Journal Article
    Description
    The Red Canarese Barb, Hypselobarbus thomassi (Day, 1874) is an endemic cyprinid fish of the rivers of the Western Ghats of India, which has been listed as ‘Critically Endangered’ in the IUCN Red List of Threatened Species. Like many of its congeners, H. thomassi is poorly known with very few verified records and voucher specimens in the past decades. Based on fresh materials collected from three west flowing rivers of Kerala, we provide information on its identity, distribution, phylogenetic position, threats and conservation. An updated conservation assessment of this species following the IUCN Red List criteria is also provided.

  • Title
    Garra kalpangi, a new cyprinid fish species (Pisces: Teleostei) from upper Brahmaputra basin in Arunachal Pradesh, India
    Type
    Journal Article
    Description
    A new cyprinid species, Garra kalpangi is described from the Kalpangi River (Brahmaputra basin) in Arunachal Pradesh, India. The species is closely similar to G. gravelyi, G. rotundinasus and G. elongata in having a shared character i.e. a weakly developed proboscis. It is distinguishable from G. gravelyi for the absence of indistinct black spot at the bases of branched dorsal fin rays and lateral stripes on the side of the body. However, G. rotundinasus possesses lateral stripe along the lateral line. Further, the absence of transverse groove at the tip of snout and longitudinal black band in medial coudal fin differentiated it from G. elongata. The detail comparative account of the 16 available species of northeastern India confirmed its distinct diagnosis as a new species under the genus. Accordingly, after thorough investigation, the taxonomic keys for all the available species under the genus from the region have also been erected in this article.

    CEPF Western Ghats Special Series: Checklist of the fishes of the Achankovil forests, Kerala, India with notes on the range extension of an endemic cyprinid Puntius chalakkudiensis
    Type
    Journal Article
    Description
    We report the results of an ichthyofaunal inventory carried out in the Achankovil Reserve Forest in the southern Western Ghats as part of a Critical Ecosystem Partnership Fund Project on lesser known freshwater fishes of Kerala . Forty-six species of freshwater fish, belonging to 17 families and 31 genera were collected from 11 sites inside the Achankovil Reserve Forest. Family Cyprinidae dominated with 21 species, followed by Bagridae, Balitoridae and Channidae (three species each). Out of the 46 species, 14 were endemic to the Western Ghats, three were endemic to Kerala region and one was exotic to the country. In this paper, we also report the range extension of an endemic cyprinid, Puntius chalakkudiensis to the Achankovil River and the Achankovil Reserve Forest. The fish diversity of this region is higher than many protected areas within southern Western Ghats, and stresses the need for immediate protection and monitoring programs.

  • Title
    A checklist of freshwater fishes of the New Amarambalam Reserve Forest (NARF), Kerala, India
    Type
    Journal Article
    Description
    The freshwater fish fauna of New Amarambalam Reserve Forest (NARF) in the Southern Western Ghats (Kerala) is constituted by 43 species belonging to 13 families and 28 genera. Family Cyprinidae dominated with 20 species followed by Balitoridae and Bagridae (four species each). NARF may harbour higher freshwater fish species diversity than in protected areas in North Kerala. The area around Maanchery in the Karimpuzha tributary of River Chaliyar needs to be designated as a priority area for freshwater fish conservation.
