Description

It is similar to '' Rhagastis acuta'', '' Rhagastis hayesi'' and '' Rhagastis velata'' but distinguishable from the first two by the forewing upperside ground colour and from the last by the shape of the labial palp, which is strongly narrowed towards the base. The forewing upperside is similar to ''Rhagastis velata'', but the ground colour ranges from pale grey to grey green (olive-green in ''Rhagastis velata''). The intensity of the dark markings varies considerably from almost absent to strongly present.
