Posterior portion of parieto-supraoccipital and compound pterotic conspicuously lighter than surrounding areas. Contra some congeners,Yshaped light mark absent on dorsal surface of snout and parieto-supraoccipital. Predorsal region slightly darker than background, but not forming transverse bar at anterior dorsalfin base and dark triangle at anterior dorsal-fin membrane absent. Trunk with two conspicuous brown bars, extending transversely from mid-dorsal region to lateral line. First bar situated between dorsal-fin base and adipose-fin origin; its anterior margin continuing as thinner bar two plates wide below lateral line, but falling short of ventral midline. Second bar on posterior portion of caudal peduncle and ending on caudal-fin base; both anterior and posterior margins of bar continue ventrally as thinner bars below lateral line to ventral midline. Fins with transverse, inconspicuous brown bands formed by concentration of chromatophores on rays; bands more visible on leading rays. Dorsal fin with 4-5 dark bands, first located at base of spine. Pectoral fin with 3-4, pelvic-, anal-, and adipose-fin spines with 1-2 dark spots. Caudal fin with 3 irregular, thin brown bands; third band best developed with posterior margin sometimes darker.

These two species share the absence of a triangular patch of dark pigmentation on the anterior portion of the dorsal-fin membrane, the lack of a Y-shaped light mark on the snout and head, which are both present in all other species, and the possession of unicuspid accessory teeth on both the premaxilla and dentary, with such dentition absent in the remaining species. The phylogenetic value of these transformations, however, remains to be evaluated.

and adjacent streams with similar features originate in pristine primary rainforest areas on the slopes of the plateaus of Saracá-Taquera National Forest (a conservation unit) where officially permitted bauxite extraction takes place. The forest is totally removed from the top of the plateaus during the mining activity and replanted after the ore is removed. Whether that activity results in adverse impacts on the stream biota is currently under investigation. Nonetheless, the presence of the new species in a single stream with such specific habitat features in that area merits special attention in the conservation of the natural condition of the lower rio Trombetas.
