|
Dorsal spines (total): 2-2; Dorsal soft rays (total): 7-7; Anal soft rays: 5-5. This species is distinguished from all other hypostomines by three unique autapomorphies: large, oval area lateral to the mesethmoid that is devoid of plates; plates in the dorsal series lateral to dorsal fin reduced to less than half what would be expected for a loricariid of its size; and, a fleshy keel along and slightly anterior to the preadipose plate and extending to dorsal caudal-fin simple ray along dorsal procurrent rays (Ref. 86603). |
| The collection area Waruma is a largely clearwater river with a slight black tint. Specimens
collected in a riffle, in a shallow side channel over polished cobble and gravel with some larger rocks covered in a grasslike vegetation. The watershed is forested (Ref. 86603). |
