The antennae are bipectinate, indicating Nearcha, and Nearcha aridaria has a good match to the forewing pattern. But the labial palpi are wrong, longer and lighter than the short black palpi of aridaria. N. curtaria and N. nullata apparently have matching palpi, but neither forewing pattern seems right. The best identification that can be made now is Nearcha sp.

Glenn - my recollection is that this was larger than most of the other small moths that were about - more the size of an Epidesmia hypenaria - to the extent that I specifically chased after it to try to get a photo. Does that fit with Nearcha? I find the size guestimate options provided with CNM submissions rather inadequate, as they cover too broad a range and it's not clear if it relates to body length or wing span. On the other hand wing span is difficult to estimate for moths that hold their wings closed or partially closed.

Nearcha spp are generally in between the size of Taxeotis spp and Epidesmia spp, and Epidesmia have unipectinate antennae like Taxeotis.
