Anablepsoides luitalimae, new species, from the rio Madeira basin, southwestern Amazonia, Brazil, and Anablepsoides vieirai, new species, from the rio Itapecuru basin, eastern Amazonia, Brazil, are described. A. luitalimae belongs to the Anablepsoides limoncochae species group and A. vieirai belongs to the Anablepsoides urophthalmus species group. Anablepsoides luitalimae is distinguished from other species of the Anablepsoides limoncochae species group by having blue pelvic fins and one longitudinal line with 6 minute contact organs on the sides of the body. Anablepsoides vieirai is distinguished from other species of the Anablepsoides urophthalmus species group by the presence of black spots in the head, opercular region and behind the eye and a higher number of scales in longitudinal series.
