Baryancistrus is a genus of fish from the armor catfish family(Loricariidae). Species of this genus have been found in Brazil ( Rio Xingu ) and Venezuela ( Rio Orinoco and Rio Ventuari )so far.

Generic characteristics

The generic features are a large head and body, odontodes on the intermaxillary bones, numerous teeth, large upper jaws and a completely armored abdomen. The most striking feature to differentiate Baryancistrus from other genera in the family of Loricariids is a small membrane that starts from the dorsal fin and may or may not extend to the attachment of the adipose fin. Other genera ( Oligancistrus , Parancistrus , and Spectracanthicus ) have a similar membrane, which is then completely connected to the adipose fin.

History of description

The genus was described in 1989 by Lucia Rapp Py-Daniel. Individual species were known zoologically much earlier. B. Baryancistrus niveatus (1855) and Baryancistrus longipinnis (1895).

Scientifically described species

So far, eight species have been scientifically described.

In the aquarium hobby, however, there are many more previously undescribed species known.
