I understand these Pterolocera species are difficu.lt to confidently separate just based on sight records alone. There are are at least two similar rufous coloured species and also several white-winged species. ''Moths in the ACT' illustrates just one: Pterolocera sp. near amplicornis ( a wjite-winged species with black venation) just like P. amplicornis itself. see here: http://lepidoptera.butterflyhouse.com.au/anth/anth-moths.html donhe may be able to add to this.
