Recent studies (Ng & Edds, 2005; Ng, 2006) recognize ten valid species of Pseudecheneis : P. sulcata (M'Clelland, 1842) , P. paviei Vaillant, 1904 , P. tchangi (Hora, 1937) , P. immaculata Chu, 1982 , P. sulcatoides Zhou & Chu, 1992 , P. sympelvica Roberts, 1998 , P. crassicauda Ng & Edds, 2005 , P. serracula Ng & Edds, 2005 , P. eddsi Ng, 2006 and P. stenura Ng, 2006 . As part of a phylogenetic study of the Sisoridae, an examination of material collected from the Ganges River drainage in the state of Himachal Pradesh in northwestern India and previously identified as P. sulcata was undertaken. This material is shown to belong to an undescribed species, the description of which as Pseudecheneis suppaetula , sp. nov. , is provided below.
