A new species of the endemic Australian genus Roscidotoga Hoare from rainforests in southern Queensland (Lepidoptera: Nepticulidae)

Abstract

The new species Roscidotoga lamingtonia is described, a leafminer on Sloanea woollsii (Elaeocarpaceae) from the subtropical rainforests of Lamington National Park, southern Queensland, and Border Ranges National Park, New South Wales. R. callicomae Hoare, 2000 is recorded for the first time from Queensland, and from Lamington National Park. These records fall within the genus' limited range in the rainforests in eastern Australia. R. lamingtonia is the second species of the genus feeding on Elaeocarpaceae. On the basis of a few possible apomorphies we hypothesize one host-shift from Cunoniaceae to Elaeocarpaceae. DNA barcodes for R. lamingtonia and R. callicomae are given.
