Abstract:
Psilochalcis brevialata Grissell and Johnson, new species, is described and illustrated based on specimens from a laboratory culture reared on Plodia interpunctella (Hübner) pupae. This species, isolated from laboratory-reared P. interpunctella placed at a culled fig warehouse in central California, is the first Psilochalcis associated with stored product pyralids. In the laboratory, P. brevialata also sucessfully parasitized Cadra figulilella (Gregson), C. cautella (Walker), Ephestia elutella (Hübner) and Amyelois transitella (Walker). The karyotype of P. brevialata showed a haploid chromosome number (n) of 6, the highest n value known for the family Chalcididae. Female P. brevialata had relatively long reproductive lives of 39.3 days, producing an average of 3.3 progeny/ day for a total of 128.7 progeny per female.
