Thanks Don. It could be. With closer comparison of pinned specimens of D caseicolor with this one, wing shape looks good. I am not totally sure about palps. I have also realised my moth has pectinate antennae. I have shots of well marked A. malacella with the same antennae. I need to further contemplate these features on various gen/sp options e.g. Ocystola although their palps are too long
I'm ot sure regarding the antennae shape for D. caseicolor or A. malacella, however there are some plain A. malacella specimenson iNaturalist showing a hint of striated antennae. Trailing shape of forewing looks different to A. malacella, but iNaturalist's AI algorithm does suggest A. malacella. Worth looking for other possibilities, I think.
found my MonAusLep 5 CSIRO p. 61 on Catameces peribapta sp "The male antennae usually have very long ciliations and the scape has a strong pecten. The second segment of the recurved labial palpi is slender, usually with appressed scales, and extends to a little beyond the base of the antenna." on A. malacella "Small moth having bright, light yellow ....... foreeings, sometimes with fuscous stigmata or pattern of broad costal and terminal streaks. The hindwings are pale ochreous......." Fig. 83,84 p. 60 shows 2 specimens of A. malacella one with very faint markings. Trying to read these descriptions (esp. details beyond above) makes my eyes glaze over and my head explode! - too many terms I can't visualise. At least this explains why some photos show the more ornate antennae - not just a terick of the light/camera angle!
