This dataset contains the digitized treatments in Plazi based on the original journal article Melo, Bruno F., Faria, Tiago C. (2024): Description of a new species of Cyphocharax from the rio Juma, rio Aripuanã basin, southern Amazon basin (Teleostei: Curimatidae). Neotropical Ichthyology (e 230122) 22 (1): 1-12, DOI: 10.1590/1982-0224-2023-0122, URL: dx.doi.org/10.1590/1982-0224-2023-0122 A new species of Cyphocharax is described from the rio Juma, which flows across the meridional Amazon basin and is a tributary of the rio Aripuanã in the rio Madeira fluvial system.

Features distinguishing the new species from congeners include a longitudinally elongated caudal peduncle blotch extending from the vertical line through the adipose-fin terminus to the base of median caudal-fin rays, the number of scale series along the lateral line and between the lateral line and dorsal-fin origin, morphometric variation, and the patterns of pigmentation along the body. The species was discovered in a lesser-explored region and appears to be an endemic of the rio Aripuanã in the southern Amazon basin.
