Type locality: Brazil.
Holotype: OUM. Male. Type Lep: n°810, Genitalia prep. 402-1960.
- Pamea excavata Walker, 1855 (original combination)
- Trogoptera excavata (Walker, 1855) in Schaus, 1928
T. excavata is supected to be the same species than T. notata (Walker, 1855) whose type is a male from Brazil as well, as written by Schaus (1896). In doubt, these have been treated as separate species by authors since Schaus.
