Neotropical Ichthyology 3 (4): 533-542, DOI: 10.1590/S1679-62252005000400011, URL: scielo.br/scielo.php?script=sci_arttext&pid=S1679-62252005000400011&lng=en&tlng=en Baryancistrus demantoides and Hemiancistrus subviridis are two new species of loricariids from southern Venezuela with an olive ground coloration and white to cream-colored or golden-yellow spots.

Baryancistrus demantoides is known only from the upper río Orinoco drainage while H. subviridis is also known from the río Casiquiare drainage. In addition to its coloration, B. demantoides can be distinguished from all other ancistrins by having the dorsal and adipose fins connected by an expanded posterior section of the dorsal-fin membrane, golden-yellow spots confined to the anterior portion of the body, and greater than 30 teeth per jaw ramus.
