Hilarini (Diptera: Empididae) from the Auckland Islands New Zealand, the Homoplastic Loss of the Male Silk-Producing Basitarsus in Two Insular Species, and Notes on the Empidoidea of the Subantarctic Islands
The New Zealand taxa of the superfamily Empidoidea (minus Dolichopodidae) are briefly summarized. Two species, Hilara ranui n. sp. and Hilarempis motumaka n. sp. (Diptera: Empididae: Empidinae), from the Auckland Islands of New Zealand, where they appear to be common, are described. Both species sho...

Summary: | The New Zealand taxa of the superfamily Empidoidea (minus Dolichopodidae) are briefly summarized. Two species, Hilara ranui n. sp. and Hilarempis motumaka n. sp. (Diptera: Empididae: Empidinae), from the Auckland Islands of New Zealand, where they appear to be common, are described. Both species show a homoplastic loss or reversal of the swollen, silk-producing, fore basitarsi characteristic of males in their respective genera. The environmental conditions of the Subantartic islands and their selective pressure on empidoid taxa are discussed. |
