Conta is a small genus of South Asian river catfishes native to India and Bangladesh.
Species
There are currently two recognized species in this genus:[1]
- Conta conta (F. Hamilton, 1822) (Conta catfish)
- Conta pectinata H. H. Ng, 2005
Description
Conta can be distinguished from all other erethistids by the presence of a very long and narrow adhesive apparatus on its thorax about six times as it is long. It also has extremely narrow gill openings, a slender body, a serrated anterior margin on the dorsal fin spine, a papillate upper lip, and 9–10 anal fin rays. The eyes are small and located dorsolaterally. There is villiform (brush-like) teeth in both jaws. The pectoral fin spine is serrated anteriorly and posteriorly.[2]
C. pectinata differs from C. conta in that it has a longer and more slender caudal peduncle and in having anteriorly-directed serrations (instead of antrorse or distally-directed serrations) the anterior edge of the pectoral fin spine.[3]
