Signal Flies of the genus Duomyia (Diptera: Platystomatidae) in the Northern Territory, Australia
Abstract
A key is given to the species of Duomyia Walker, 1849, (approximately 26) recognized in the Northern Territory of Australia. The following new species are described: D. nodosa, D. rapida, D. grahami, D. tricurva, D. bucina, D. recta, D. prensans, D. praeflava, D. korneyevi, D. lana, D. collessi, D. maceveyi, D. whittingtoni. Duomyia sericea Hendel and D. serra McAlpine are newly recorded for the Northern Territory; D. foliata McAlpine is newly recorded for New South Wales; D. tomentosa Hendel is newly recorded for Western Australia; and D. eremia McAlpine is newly recorded for South Australia. The question of possible recent extinction of D. irregularis Malloch is raised, and the urgent need to establish the population status of other rarely seen species is mentioned.
