Scutellum flattened ( Fig. 4 F View Fig ). Tegulae rosy-yellow ( Fig. 4 B, F View Fig ).
Tegmina: ( Fig. 4 A View Fig ) Black-brown, with clavus and large marking on corium along apex of clavus, pink; irregular brownish white markings on corium, along clavus, along costal margin and along sutural margin at level of nodal line; small white spots along apical margin; rosy patch along costal margin at nodal line.
Hind wings: ( Fig. 4 A, C View Fig ) Dark brown with central elongate hyaline patch. Three elongate orange markings originating from base: one extending on anal area to half length; one along claval joint on 2/3 of length and one along costal margin on basal third.
