This is a poorly understood species that occurs in South American lowland forest. It has been recorded from French Guiana, Peru, Bolivia, and Brazil (AM, MT). New material examined. French Guiana.- 1♀: Approuague - Mapaou, 4°31'N , 52°13'W , 29. XII. 2008, S. Fernandez leg. (CF) (Fig. 13). Peru.- 1♀: SM, Upper Huallaga Valley, V-VI 2000, Purch. Thorne 7/01, gen. prep. CF n°428 (USNM). Brazil.- 1♂: MT, Diamantino, Alto Rio Arinos, 5.X.1998, E. Furtado leg., gen. prep. CF n°446 (MC 254).

We associate females from French Guiana (Figs 13, 36), Peru, and Bolivia with this species. They have the same ventral wing pattern, a similar geographic range, and limited COI DNA sequences are the same. COI DNA sequence. The sequence of a female from French Guiana (CF-LYC-039) is the same as (0% divergence) that of the male paratype from Peru (CF-LYC-020). This female is the first record of Oenomaus magnus from French Guiana.
