Mesostenus gracilis Cresson, 1864
I recorded a number of stored product phycitines as hosts of this species in the 1979 catalog of Hymenoptera of America north of Mexcico, but I believe it has since been reared from Plodia interpunctella as well. Searches of the web show that it has at least been associated with Plodia interpunctella.
