Agaraea nigrotuberculata Bryk, 1953 syn. n. (Fig. 2)
Agaraea klagesi (Rothschild, 1909a: 290) was described based on two female syntypes from Fonte Boa, Amazonas, Brazil. One female is deposited in NHUK, labeled “Fonte Boas, Amazonas, August 1906 (S. M. Klages)”, is here designated lectotype (Fig. 1). It is in good condition. Furthermore, A. nigrotuberculata Bryk, 1953: 214 was described from a male holotype from Rio Purus, Amazonas [Brazil], and is deposited in NRS (Fig. 2). The holotype of A. nigrotuberculata has few scales on its wings and is faded. Despite of genitalia being unknown for both species, the habitus of A. nigrotuberculata matches the habitus of A. klagesi and the type localities are on the same biogeographical area. For these reasons, the new synonymy is here proposed.
