Agenysa peruviana Spaeth 1915

New Record ( Figure 1A , Table 1)

One of us (RW) observed several adults feeding on a Mikania species (Asteraceae) on at least four separate occasions between 2003–2010 in Peru: Loreto Province: Picuroyacu, 150 m, in forest clearings and at forest borders. RW also found individuals feeding on a different Mikania species in Brazil: Amazonas Province, Tabatinga, 4°13’48.30” S, 69° 56’12.45” W, 200 m, understorey of riverine forest, 4.IX.2008. Brazil is a new country record and Mikania is the first host record for this species.
