Monobolodes undatifascia Holloway sp. n.

♂♀ 10-11mm.

This species is similar in general colouring to rectifascia, but the pale forewings of the male are more obscurely marked, and generally rather wavy, striate.

The female wings are uniform grey-brown, with similarly obscure, darker wavy striations.

The male genitalia have the vinculum doubly looped to support hair-pencils as in rectifascia, but these are multiple rather than single.

The valve is narrow, distinctly sclerotised, and bears a sparse scattering of very short setae.

Both sixth and seventh abdominal sternites have patches of modified scales.
