Resumen

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.
