Mnesteria sideraula

Description

Mnesteria sideraula is a moth in the Lecithoceridae family. It was described by Meyrick in 1916. It is found in Sri Lanka. The wingspan is 16–18 mm. The forewings are pale brassy-yellow, in females with the dorsal half deep ochreous-yellow. There is a small spot of dark bluish-leaden suffusion on the base of the costa and a dark bluish-leaden-metallic streak from the base along the fold to beyond one-third, and a similar streak in the disc from one-third to two-thirds. In males, there is a rather thick dark fuscous median longitudinal streak from the base to the apex, including the two preceding, in females less strongly marked and on the anterior half of the wing more or less obsolete. The hindwings of the males are pale ochreous tinged with grey towards the costa, with a long dense pale ochreous hairpencil lying along the submedian groove from the base. The female hindwings are grey.
