Size: body 3mm, forewing 2.3mm
This one keys out to Epyrinae and then Epyris in all 3 keys that I tried: Evans 1964 (1), Terayama 2003 (2), and Azevedo et al. 2018 (3). The closest alternative to Epyris in the Evans and Azevedo et al. keys is Bakeriella but I think that genus can be safely ruled out based on the reported rarity of that genus (Synopsis of Bakeriella by Azevado, page 501 ) and because that genus is supposed to have a transverse carina on the pronotum (as well as some species having longitudinal carinae). In the Azevedo Bakeriella key, all of the species lacking a carinate pronotum are from South America. The closest alternatives in the Terayama key are Isobrachium and Holepyris. The former lacks notauli while the latter has "3 prominent lobes" on the clypeus and the scutellum has "a transverse, undivided groove" rather than distinct pits.

After all of that, I could be way off and would appreciate some expert input on this one. TIA

Dr. Wesley Colombo kindly examined these photos and informed me of a recent revision of this subfamily and of the genus Epyris (1). He says this isn't Epyris under the revision but "it's probably between a Gracilepyris or Psilepyris. I'm more confident in the latter."
