The genus Isozulia is re-characterized and compared with Aeneolamia. Two species are transferred from Aeneolamia to become I. astralis (Distant) comb. n. and I. christenseni (Lallemand) comb. n., and I. flamen Fennah is reduced to a subspecies, I. astralis flamen, stat. n. Two populations from Ecuador and Peru are described as new species, I. minor sp. n. and I. charaxus sp. n., respectively, and a population of I. christenseni in Jujuy Province, Argentina, is recognised as a distinct subspecies, I. c. jujuyana subsp. n. Both this subspecies and I. minor are reported as attacking sugarcane.
