Diagnosis
This new species can be recognized by having the median pronotal sulcus foveolate, the anterior margin of the PPP truncate in lateral view and the hind wing with three distal hamuli. This species is similar to H. remota sp. nov. for having the legs partly dark brown. It can be distinguished from the latter by having the hind wing with the distance between the 1 st and 2 nd distal hamuli 1.5 × the distance between 2 nd and 3 rd distal hamuli (2.0 in H. remota ) and the apex of the PPP is truncate in lateral view (rounded in H. remota ).
Etymology
The specific epithet is a combination of ‘ varius ’ (Latin for ‘different’) and ‘ color ’ (Latin for ‘tint’), and refers to the variably coloured legs of this species.
