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)

Abstract

<jats:p> <jats:italic>Jarra painei</jats:italic> sp.n. is described from Victoria and South Australia, reared from larvae of <jats:italic>Phoracantha semipunctata</jats:italic> (Cerambycidae). This beetle has become an exotic pest on eucalypt trees in California, South America, Africa and the Mediterranean region. <jats:italic>J. painei</jats:italic> is the fourth species of <jats:italic>Jarra</jats:italic> to be associated with <jats:italic>Phoracantha</jats:italic>, and it is described to support assessment of its biological control potential in California. the relationships of <jats:italic>J. painei</jats:italic> are discussed and a key presented to separate it from other described <jats:italic>Jarra</jats:italic> species. Information is presented on other parasitoids associated with <jats:italic>Phoracantha</jats:italic> in southeastern Australia. <jats:italic>Xorides australiensis</jats:italic> (Szépligeti) (Ichneumonidae) is reared from <jats:italic>P. semipunctata</jats:italic> for the first time.</jats:p>
