Última Baryancistrus demantoides and Hemiancistrus subviridis, two new uniquely colored species of catfishes from Venezuela (Siluriformes: Loricariidae) Neotropical Ichthyology Werneke,David C.; Sabaj,Mark H.; Lujan,Nathan K.; Armbruster,Jonathan W.. 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. Hemiancistrus subviridis can be separated from all other ancistrins by coloration, lacking a connection between the...

Hemiancistrus guahiborum, new species, is described from the Orinoco River drainage of Venezuela. Hemiancistrus guahiborum can be separated from all other Hemiancistrus and all Peckoltia except P. braueri and P. cavatica by having an orange edge to the dorsal and caudal fins. Hemiancistrus guahiborum can be separated from Peckoltia cavatica and P. braueri by having the dorsal fin with separated light spots or uniformly colored (vs. with dark spots forming bands) and the sides either solidly colored or with tan blotches (vs. with dark dorsal saddles).

Ano: 2005 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1679-62252005000400012 Description of a new Lithoxus (Siluriformes: Loricariidae) from the Guayana Highlands with a discussion of Guiana Shield biogeography Neotropical Ichthyology Lujan,Nathan K.. Lithoxus jantjae, new species, is described from above Tencua Falls in headwaters of the Ventuari River, a white- to clearwater river flowing west from the Maigualida and Parima mountains in the Guayana Highlands of southern Venezuela. Lithoxus jantjae represents a nearly 600 km westward range expansion for a genus historically known only from Guyana, Suriname, French Guiana, and Brazil. Lithoxus jantjae shares with other species of Lithoxus a dorsoventrally depressed body and a large, papilose oral disk with small toothcups and few teeth. It can be distinguished from congeners by a unique combination of characters including 12 branched caudal-fin rays, medial premaxillary tooth cusps enlarged, and a convex posterior margin of the adipose-fin membrane....
