From Planet Catfish for Panaque cochliodon:
"Generally identified as Panaque suttonorum (previously P. suttoni) and although similar, this iconic species does not closely match the description in Schultz's original paper. Shane Linder offers the following on the possible identity of this species: P. suttonorum, Schultz 1944, the scientific name commonly applied to the blue-eyed pleco in the aquarium hobby, is an incorrect identification. Schultz described live specimens of P. suttonorum as, "Uniformly greyish...basal two-thirds of the paired fins black, and the tips of these fins white; the posterior margin of dorsal is white, a narrow white bar across caudal peduncle, middle of caudal fin white then some black blotches; the tips of the rays are white." While P. suttonorum sounds like a very attractive fish, this is clearly not a description of the blue-eyed pleco found in the hobby. P. suttonorum is restricted to the Lake Maracaibo basin and virtually no aquarium fishes are exported from there. The fishes from that basin are very unique and if we had a shipment from there we would know it immediately. We also know that blue-eyed pleco shipments come from Colombia and P. suttonorum is restricted to Venezuela."
