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.

TEGMINA ( Fig. 3 A–C). Brown, progressively more reddish towards base; reddish tint more visible ventrally; broad subbasal transverse band of white wax; at mid-length near costal margin, a larger oval spot covered in white wax and narrowly margined in black posteriorly; irregular marking of white wax ventrally corresponding to dorsal oval marking; numerous small spots of white wax on central portion of tegmina; on apical ⅓, several concentric, irregular and interrupted rows of narrow dark brown lines, parallel to apical margin of tegmen, number of rows varying from 2 anteriorly along costal margin to 7–8 in middle; costal and sutural margins subparallel; apical margin broadly rounded.

HIND WINGS ( Fig. 3A, C ). 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.
