"Amblyceps" is a genus of catfishes (order Siluriformes) of the family Amblycipitidae.

Taxonomy

The genera "Amblyceps" and "Liobagrus" are sister group pair that is, in turn, sister to "Xiurenbagrus".

Distribution and habitat

"Amblyceps" species are distributed throughout south and southeast Asia. They typically inhabit fast flowing hill streams or fast-flowing stretches of larger rivers.cite journal|url=http://rmbr.nus.edu.sg/rbz/biblio/53/53rbz243-249.pdf|title="Amblyceps carinatum" a New Species of Hillstream Catfish from Myanmar (Telestei: Amblycipitidae)|first=Heok Hee|last=Ng|journal=The Raffles Bulletin of Zoology|year=2005|volume=53|issue=2|pages=243–249|format=PDF] "Amblyceps" are mainly distributed in India and the Malay Peninsula.cite journal|title=A new species of amblycipitid catfish, "Xiurenbagrus gigas" (Teleostei: Siluriformes), from Guangxi, China|first=Yahui|last=Zhao|coauthors=Lan, Jiahu; Zhang, Chunguang|journal=Ichthyological Research|year=2004|volume=51|pages=228–232|doi=10.1007/s10228-004-0220-z] Three species are known from Myanmar, "A. murraystuarti", "A. mucronatum", and "A. carinatum".

Description

"Amblyceps" 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. In most species the caudal fin is deeply forked; "A. apangi" and "A. murraystuarti" differ in having their caudal fin truncate. "Amblyceps" species may reach about 100 millimetres (3.94 in) SL.cite journal|title="Xiurenbagrus", a New Genus of Amblycipitid Catfishes (Teleostei: Siluriformes), and Phylogenetic Relationships among the Genera of Amblycipitidae|first=Xiaoping|last=Chen|coauthors=Lundberg, John G.|journal=Copeia|year=1995|issue=4|pages=780–800|doi=10.2307/1447027|volume=1995]
