A.D. Austin and P.C. Dangerfield (1997)
A new species of Jarra Marsh and Austin (Hymenoptera : Braconidae) with comments on other parasitoids associated with the eucalypt longicorn Phoracantha semipunctata (F.) (Coleoptera : Cerambycidae)
Australian Journal of Entomology 36 (4), 327-331
Abstract: Jarra painei sp.n. is described from Victoria and South Australia, reared from larvae of Phoracantha semipunctata (Cerambycidae). This beetle has become an exotic pest on eucalypt trees in California, South America, Africa and the Mediterranean region. J. painei is the fourth species of Jarra to be associated with Phoracantha, and it is described to support assessment of its biological control potential in California. The relationships of J. painei are discussed and a key presented to separate it from other described Jarra species. Information is presented on other parasitoids associated with Phoracantha in southeastern Australia. Xorides australiensis (Szépligeti) (Ichneumonidae) is reared from P. semipunctata for the first time.
