[[
Pseudecheneis Blyth
]]
Sisorid catfishes of the genus
Pseudecheneis Blyth, 1860
are diagnosed by a thoracic adhesive apparatus consisting of a series of transverse ridges (laminae) separated by grooves (sulcae) (de Pinna, 1996; Roberts, 1998), and are found in the upper reaches of rivers throughout the Subhimalayan and Indochinese region. 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.
