Abstract

Two new species of Fergusonina flies are described from terminal leaf bud galls on Eucalyptus from south-eastern Australia. Fergusonina herbaservus Nelson sp. nov. and Fergusonina manchesteri Purcell sp. nov. are the first species of fly from the genus Fergusonina to be described from Eucalyptus stellulata (black sallee) and E. viminalis (manna gum), respectively. The two species can be distinguished from all other described Fergusonina by host specificity, adult colour and setation, morphology of the genitalia, and morphology of the dorsal shield. These records represent the first record of Fergusonina galling for black sallee and a new Fergusonina gall type for manna gum.
