Petalothyrsa microphthalma Meyrick, 1931 | |
The wingspan is about 8 mm. The forewings are whitish, closely speckled with brown with slight dark fuscous marks on the costa at the base and one-fifth and a rather broad direct brown median fascia, anteriorly mixed with blackish on the costa and on the dorsal half. Towards the dorsum these scales are rough and form projecting teeth. There is a black discal dot ringed with white just beyond this and the posterior half is irregularly suffused with brownish on the dorsal half with some irregular black scales posteriorly. The hindwings are grey, thinly scaled and subhyaline (almost glass like) in the disc anteriorly.[2]
