Diagnosis
Male
Unknown.
Female
(
Fig. 3
)
Immediately recognized by the combination of the following characters: (1) tegmina with a transverse white waxy band near base and a large, oval, white waxy spot along costal margin (but not reaching the latter at about mid-length) (
Fig. 3
A–B); (2) tegmina and posterior wings with concentric rows of narrow brown stripes parallel to apical margin (
Fig. 3
A–C); (3) ground colour of posterior wings turning to pale brown on apical half (
Fig. 3A, C
).
Etymology
The specific name is derived from the Latin adjective ‘
bellissima
’, meaning ‘most beautiful’. It refers to the colour and pattern of the tegmina and wings.

7–8 in
middle; costal and sutural margins subparallel; apical margin broadly rounded.
HIND WINGS (

). White basally turning to yellow-brown on distal half; distal half with numerous more or less transverse brown markings arranged in concentric rows parallel to distal margin towards apex; brown markings merging into irregular interrupted lines on distal 1/5; apical margin broadly rounded; postclaval margin with white waxy suffusions; inner part of cells semi-transluscent on basal white portion.
