Bryconaethiops yseuxi Boulenger, 1899, originally described from “Haut Congo”, is rehabilitated. The species was synonymized, successively with B. microstoma (Gunther, 1873) and B. macrops Boulenger, 1920, subsequently rehabilitated, and then again considered as a junior synonym of B. microstoma. Bryconaethiops yseuxi is here considered as a valid species, easily distinguished from all other Bryconaethiops species by its small size (maximum: 72.2 mm SL), 7.5 rows of scales between the dorsal‐fin origin and the lateral line; 11–13/1/8–12 gill rakers on the first gill arch and long dorsal‐fin and anal‐fin bases, respectively, 15.7–17.6% of SL and 22.7–25.9% of SL.
