Diagnosis
This new species can be recognized from other species of this genus by having the foveae on the dorsal pronotal area sparser and shallower than those on the head, the length of the PPP slightly longer than its width at the base, the anterior margin of the PPP rounded in lateral view, the legs reddish brown and the hind wing with three distal hamuli.
Etymology
The specific epithet ‘ unicolor ’ is a combination of the Latin words ‘ uni- ’ and ‘ color ’ which refers to the unicoloured reddish-brown legs of this species.
