This one looks very like Pseudanapaea denotata in Paul Zborowski's 'A Guide to Australian Moths' . A very small Limacodid resting under lights on the margin of the Dandenong Ranges NP. Web shots of P transvestita and denotata seem mixed. Work to be done yet. Thanks experts.
I HAVE TEMPORARILY ADDED THE PAUL ZBOROWSKI PHOTO FROM THE BOOK FOR COMPARISON.
