Labanda viridumbrosa Holloway sp. n.
♂ 17mm, ♀ 15mm.
The male has bipectinate antennae as in umbrosa but the forewings are green and black rather than brown and black, with clearer, rather zig-zag fasciation, particularly in the marginal half.
Like umbrosa, there are darker transverse bands medially and between the postmedial and submarginal.
In the male genitalia the costal process of the valve is similar to that of umbrosa but the aedeagus vesica has only two distal spines rather than a cluster, though there is an additional more basal row and also a short series of teeth at the junction with the aedeagus, features lacking in umbrosa.
