Redescription, new distribution record, DNA sequence and length-weight relationship of the Eel-loach Pangio pangia (Cypriniformes: Cobitidae) in the River Ganges Basin, India
The Eel-loach Pangio pangia has never been reported from East India in the River Ganges. In August, 2011, we collected a total of 39 individuals of this species during fish diversity explorations in River Ganges at Narora. This is the first record for Uttar Pradesh (North India). We present additional diagnostic features and description for this species previously known only from very old descriptions generally based on preserved specimens. Additionally, a molecular signature of the internal transcribed spacer 2 (ITS2) region between 5,8S and 28S ribosomal RNA genes was sequenced and submitted to NCBI (Accession No. JQ619873). The length-weight relationship showed allometric growth as b value of overall length-weight relation was 2,71 at p<0,00 which, ranged from 2,65 to 2,76. The substantial threats and issues regarding unawareness of this understudied fish species are highlighted to help sustaining fish biodiversity in India. KEY WORDSNew distribution, Pangio pangia, length weight relationship, River Ganges, India.

KEY WORDSNew distribution, Pangio pangia, length weight relationship, River Ganges, India. La ánguila Pangio pangia del río Ganges de las Indias Orientales, nunca había sido reportado para el sitio, resultando en una dificultad para determinar no solamente su localidad, sino también la razón de su extinción en la cuenca del Ganges de la India. En agosto de 2011, registramos un total de 39 individuos de esta especie durante exploraciones de diversidad de peces en el río Ganges en Narora; por primera vez en Uttar Pradesh (norte de India). Las características diagnósticas y la descripción de esta especie han sido actualizadas ya que la información disponible era muy vieja y en general basada en muestras de especímenes preservados. Adicionalmente, como una firma molecular de esta especie se ingresó a NCBI GenBank (N º de Acceso JQ619873) la región interna transcrita espaciadora 2 (ITS2) entre 5,8S y 28S ARN ribosomal. La relación talla-peso mostró un crecimiento alométrico como valor de b, en general la relación talla-peso fue 2,71 (p <0,00), que van desde 2,65 a 2,76. Las amenazas sustanciales y cuestiones relativas a la inconsciencia de esta especie poco estudiada fueron destacados para la sostenibilidad de la biodiversidad de peces en la India.
