The new genus Ardernomyia, with one new species in New Zealand and seven new species in the southwestern corner of Western Australia, is described, illustrated and discussed. Keys to the males and females of the eight species are provided. The new genus belongs to the Monohelea complex and forms the sister group to (Monohelea Kieffer + Heterohelea Clastrier) + (Downeshelea Wirth & Grogan + Allohelea Kieffer). Zoogeographic patterns among the related genera suggest southern hemisphere diversification but further intrageneric phylogenetic resolution is needed of these other genera to provide specific resolution. A phylogeny based solely on male genitalic differences indicates that the single species from New Zealand is the sister group to the remaining seven species, all from Western Australia. The Australian species are resolved other than a polychotomy between three of them. The immatures, almost certainly aquatic or semiaquatic, are unknown. Strikingly, seven of the new Australian species are present at a single site, with two of these also found further north. The limited region is a known biodiversity hotspot otherwise and it seems certain that further species will be discovered. Four unassociated and unnamed species of females are described and their possible identification is discussed. A list of other genera collected in Western Australia is provided and discussed, further indicating the need for further sampling of this interesting family.

Parasitic interactions play a central role in shaping insect diversity; however, many host-parasite associations remain poorly documented, particularly among Diptera. Species of Forcipomyia (Microhelea) are known ectoparasites of other insects, yet information on their host associations is still fragmentary. The Fuliginosa species-group is known to be ectoparasite of larvae of Lepidoptera and Hymenoptera. In this study, we present the first global synthesis of ectoparasitism by Forcipomyia...
