The Tribe Dufouriini (Diptera: Tachinidae: Dexiinae) recorded from Australia with the description of two new species

Abstract

Rondania albipilosa sp. nov. and R. cinerea sp. nov. are described and Chetoptilia angustifrons Mesnil is recorded from Australia, confirming the presence of the tribe Dufouriini in the Australasian Region. Other Australian species of Rondania are known, but remain undescribed because insufficient specimens are available to adequately resolve species limits. The distributions of Chetoptilia Rondani and Rondania Robineau- Desvoidy are extended to Australia. Two host records are noted, that of Chetoptilia angustifrons emerging from prepupae of a chrysomelid beetle and Rondania cinerea from an adult weevil. The presence of fully developed first instar larvae in the oviducts of specimens of Rondania albipilosa and R. cinerea indicate ovolarviparity, consistent with other Dexiinae.
