Cryptophasa isoneura

Cryptophasa isoneura is a moth in the family Xyloryctidae. It was described by Lower in 1902. It is found in Australia,[1] where it has been recorded from Queensland, South Australia and Victoria.

The wingspan is about 24 mm. The forewings are ochreous-whitish, irregularly suffused with rather thick streaks of smoky fuscous, especially along the costa and towards the termen. All veins are more or less outlined with black and there is a moderately large quadrate ferruginous spot at the posterior extremity of the cell. There are some ferruginous scales just below the base of vein 2, as well as a moderate ferruginous band along the termen to the apical fifth of the costa, obliterating the lines along the veins. There is a sharp black line along the termen. The hindwings are black with the basal and inner marginal areas greyish, strongly haired. There is a ferruginous band and line along the termen.

The larvae feed on Casuarina species. They bore in the stem of their host plant.[2]
