Thudaca crypsidesma is a moth in the Depressariidae family. It was described by Meyrick in 1893. It is found in Australia, where it has been recorded from South Australia, Victoria,[1] Tasmania and Western Australia.
The wingspan is 19-20 mm. The forewings are snow-white with bright orange markings. The costal edge is blackish near the base and there is a moderate streak immediately beneath the costa from the base to the costa before the apex. A subdorsal streak, black-edged above, is found from the base to the anal angle and there are two black-edged straight transverse streaks, the first from the subcostal streak at two-thirds to above the middle of the subdorsal but not nearly reaching it, suffusedly barred with blackish-grey above the middle, the second from the extremity of the subcostal to the subdorsal before the extremity, suffused with blackish-grey towards the costa and on a bar above the lower end. There is also a blackish line along the hindmargin. The hindwings are grey.[2]
The larvae probably feed on Leptospermum species.[3]
