Euchaetis endoleuca is a moth in the family Oecophoridae. It was described by Edward Meyrick in 1888. It is found in Australia, where it has been recorded from South Australia and Western Australia.[1]
The wingspan is about 30 mm. The forewings are pale greyish ochreous, closely sprinkled with light brown reddish and with a rosy costal edge, except near the apex. The markings are blackish. There is a large dot on the inner margin near the base, and two small dots above it, as well as a dot in the disc at one-fourth, connected with the inner margin before the middle by a cloudy irregular line. There is also a dot in the disc before the middle, a second on the fold rather beyond it and a third in the disc at two-thirds. There is a very indistinct oblique irregular transverse line passing through the first two of these, and another more curved through the third, tending to unite in a suffusion on the inner margin. A well-marked series of dots runs from the costa beyond the middle to the inner margin before the anal angle, unevenly bent outwards and there is a hindmarginal row of small dots. The hindwings are whitish, with a rather narrow suffused pale fuscous hindmarginal border.[2]
