Cryptophasa sarcinota is a moth in the Xyloryctidae family. It was described by Meyrick in 1890. It is found in Australia, where it has been recorded from Queensland. The wingspan is about 35-53 mm. The forewings are pale greyish-ochreous, brownish-tinged and with a large black dot in the disc at one-third, a second on the fold beneath the middle, and two others transversely obliquely placed, and sometimes connected by a fine line in the disc at three-fifths, the lower anterior. There is a row of black dots along the hindmargin and apical half of the costa. The hindwings are fuscous, tinged with blackish towards the basal third, the base with ochreous-whitish hairs.
