Brasema gemmarii
Brasema gemmarii is a North American eupelmid wasp species associated with oak gall wasps (Cynipini). It was first described by Ashmead in 1886. Recent research has expanded its known distribution within the United States. Like other members of its genus, it is presumed to be a parasitoid of cynipid gall wasps, though specific host records for this species were not detailed in the available source.
