Amblyceps

Amblyceps is a genus of fish in the family Amblycipitidae.[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 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]
