FIVE NEARCTIC AND ONE INTRODUCED EUPHORINE SPECIES (HYMENOPTERA: BRACONIDAE) THAT PARASITIZE ADULTS OF CRUCIFER-INFESTING FLEA BEETLES (COLEOPTERA: CHRYSOMELIDAE)

Abstract

Abstract A key to females is presented for six euphorine species that parasitize adults of crucifer-infesting flea beetles. Five of the species, Townesilitus psylliodis (Loan), Microctonus punctulatae sp. n., M. pusillae Muesebeck, M. vittatae Muesebeck, and M. zimmermanni sp. n., are Nearctic in distribution; the sixth, T. bicolor (Wesm.), was recently introduced into Manitoba from Europe. The two new species are described, and biological information is presented for T. bicolor , T. psylliodis , M. punctulatae , and M. vittatae .
