Amblyceps is a
genus of
fish in the
familyAmblycipitidae.[1] The genera Amblyceps and Liobagrus are
sister group pair that is, in turn, sister to Xiurenbagrus.[2] These
species are easily distinguished by the presence of
pinnate processes along with the median
caudal-fin rays (although these processes may be poorly developed in some species), a prominent cup-like skin flap above the base of the
pectoral spine, and the
adipose fin largely separate from the
caudal fin.[3] In most species the caudal fin is deeply forked; A. apangi and A. murraystuarti differ in having their caudal fin truncate.[3]Amblyceps species may reach about 100 millimetres (3.94 in)
SL.[2]
Distribution and habitat
These species are
distributed throughout
south and southeast Asia. They typically inhabit fast flowing hill streams or fast-flowing stretches of larger rivers.[3] This genus is mainly distributed in
India and the
Malay Peninsula.[4] Three species are known from
Myanmar: A. caecutiens, A. murraystuarti and A. carinatum.[3]
