While I first thought this was S. meyrecki I now think this is the subtly different S. emmetropis which is a grey moth lacking the overwall brownish colouration of S. meyrickii and does not have a white spot/streak mid forewing. A new species record for CNM if confirmed. The ALA shows records of this species from Tasmania, southern Victoria and southern NSW. Bold Systems 4 shows records from southern NSW also (not the ACT).
