Idarnes thanatos Farache, Rasplus, Pereira & Compton, 2017. Holotype: in Museu de Zoologia, Universidade de São Paulo, São Paulo, Brazil (MZSP). Type locality: in amber resin from La Bucara amber mines, Dominican Republic.


Dominican Republic (fossil in amber).


Host fig: unknown. The Dominican amber was dated as Mid-Miocene (15–20 million years ago) and its resin was probably derived from a single extinct Hymenaea (Papilionaceae) species (Iturralde-Vinent and MacPhee, 1996). The specimen was acquired from a commercial source and according to the suppliers was excavated in the La Bucara amber mines in 2008. The amber piece also included a large leaf/ leaflet, an ant specimen (Formicidae) and another chalcid wasp (Farache et al., 2017).
