It is shown that Catochrysops trifracta Butler, 1884, currently a synonym of the widespread old world Euchrysops cnejus (Fabricius, 1798) is a junior subjective synonym of the neotropical species Hemiargus hanno (Stoll [1790]). To fix the taxonomic identity of the name Catochrysops trifracta Butler, 1884, I designate a lectotype.
