Three new species of Dolichogenidea Viereck (Hymenoptera, Braconidae, Microgastrinae) from Australia with exceptionally long ovipositors

The subfamily Microgastrinae contains an extraordinarily rich diversity of parasitoid wasps which parasitise larval lepidopterans. The Australian fauna has generally been poorly studied, particularly for the very speciose genera. One such genus is Dolichogenidea Vierek, which in Australia is known from only six described species. Here we describe three new species of Dolichogenidea from Australia, which are distinguished by possessing extremely long ovipositors compared with the typical form for the genus. These are D. finchi Fagan-Jeffries & Austin, sp. n., D. mediocaudata Fagan-Jeffries & Austin, sp. n., and D. xenomorph Fagan-Jeffries & Austin, sp. n. In describing these new species we also discuss relationships within the genus, and the diversity and biology of the Australian fauna

Synopsis of the parasitoid wasp genus Cotesia Cameron, 1891 (Hymenoptera: Braconidae: Microgastrinae) in Australia, with the description of seven new species

The genus Cotesia Cameron, 1891 is one of the most diverse of the Microgastrinae, a subfamily of wasps that are exclusively endoparasitic on lepidopteran larvae. Species of Cotesia are widely utilised as biological control agents across the world. In Australia, there are currently 10 confirmed native species as well as four species introduced for the management of lepidopteran pests. The genus is morphologically conserved and has not been studied in the Australasian region for many decades. In this study, we use both comparative morphology and sequence data from the COI gene to delineate species, and in so doing describe seven new species from Australia: C. lasallei sp. nov., C. medusae sp. nov., C. ocellata sp. nov., C. reidarum sp. nov., C. scripta sp. nov., C. tjapekki sp. nov. and C. wonboynensis sp. nov., raising the number of species of Cotesia formally recorded in Australia to 21. We also provide updated descriptions of the previously described native species, diagnoses for the introduced species and a key to all currently described species found on the continent and from Papua New Guinea. This study treats only a fraction of the likely diversity of Cotesia, but provides a solid framework for future work

The genus is known from five species, including the one described here. It is found broadly across the arid zone from central Queensland to the western margin of the continent, with two species occurring on Cape York Peninsula. The genus is apparently absent from the eastern coastal margin, and temperate/Mediterranean south-east and south-west corners of the continent. However, given that specimens are rarely collected, the distribution of the genus may be broader than is currently documented.</p> <p> <b> Key to species of <i>Cercobarcon</i></b> </p> <p>1.
