Vertex with black pile. Antenna entirely orange. Eye sparsely pilose, pile whiteish. Thorax: Thorax entirely iridescent blue and green, shining, pollinosity free. Legs dark metallic blue, with some greenish iridescence. Hind femur unmodified, with only a few weak, black setulae apicoventrally. Pleuron black pilose. Scutum mostly black pilose, with some white pile anterior to transverse suture, and laterally to postalar callus. Scutellum black pilose. Halter dark brown. Calypter dark brown. Wing colourless, with bare areas at the bases of cells c, cua, m 4, and dm, anterior half of cell bm bare. Abdomen: Abdominal sclerites entirely iridescent bluish-green. Tergites 1–3 black pilose.

Etymology: This species is named after the lead author’s partner, Aislinn Wyatt. Throughout all ADY’s years of syrphidology and post-secondary education, Ais has been the most loving partner anyone could ever ask for, as well as the occasional field assistant.

Specimens examined: HOLOTYPE: AUSTRALIA: Queensland: Lamington National Park, Lahey Memorial , -28.188 153.121, 15.xii.2008 – 6.i.2009, Malaise trap. G. Monteith. QM Reg. No. T 222154 (1♀, QM) GoogleMaps . PARATYPE:

Queensland: Kuranda. ANIC Database No 29 034453 (1♀, ANIC) .

Discussion: This species is known from only two female specimens, one collected in Kuranda QLD(Queensland), and one from Lamington National Park QLD. This widely disjunct distribution suggests that the species is present but rare across the east coast of Australia. Although no male has been collected, the holotype was successfully DNA barcoded, so if a male is collected in the future it can be confidently matched to the holotype using DNA evidence. The barcode data extracted from the holotype is publicly available on the BOLD website (process ID: SYCNC805- 18) and on Genbank ( MK073252 View Materials ), as detailed above in the Material and methods section.
