Oxyethira (Trichoglene) triangulata Wells 1981, 108, figs 11–13

Material examined. NORTHERN TERRITORY: 1 male, Petherick’s Rainforest Reserve, 6–7.vi.2015, J. Schult, light trap (NTM).

Remarks. Distributions of many microcaddisfly species extend across the north of Australia, so a westward extension to the distribution of O. triangulata is unsurprising. It is surprising, however, that despite quite extensive light-trapping in the Top End, this is the first record for this species. Further effort is needed to determine if it is established there.
