Garrha leucerythra is a moth in the family Oecophoridae. It was described by Edward Meyrick in 1883. It is found in Australia, where it has been recorded from New South Wales and Tasmania.[1]
The wingspan is 18.5–21 mm. The forewings are pale pinkish ochreous, sometimes rather strongly pinkish and the costa narrowly carmine pink with the tips of the scales whitish. There is a dark fuscous dot in the disc before the middle, a second, slightly larger, in the disc beyond the middle, and a third obliquely beyond the first on the fold. Sometimes, there is a short obsolete oblique row of three grey dots from costa at two-fifths, and occasionally two or three other scattered dark scales towards the base. There is an ill-defined, often almost obsolete, transverse row of irregular dark fuscous dots, from the middle of the costa very obliquely outwards to the disc at five-sixths, then sharply bent and nearly parallel to the hindmargin, ending on the inner margin before the anal angle. The hindwings are whitish, posteriorly faintly tinged with ochreous grey.[2]
