<J genitalia. Uncus weakly bifurcate apically, dorsal carina continuous anteriorly with 

 mid-dorsal swelling on tegumen; apex of valve spatulate; aedeagus usually with small, 

 acuminate process near apex. 



9 genitalia. Posterior margin of 7th sternite deeply emarginate medially; lamella post- 

 vaginalis broadly V-shaped; ductus bursae rugose posteriorly, especially strongly so near 

 middle of ductus. 



Distinguished from its close relatives, godmani, fafner and cingulata by the colour- 

 pattern of the wings. In godmani the whole of the forewing apical area is yellow, 

 and in cingulata and fafner the hindwings are uniformly brown. 



Seitz (1922 : 375) describes the larva as black, and like a Halisidota larva, with 

 no hair bundles but with yellowish white hair pencils anteriorly and posteriorly; 

 the food plant is recorded as a guava, Psidium pyriferum (Myrtaceae).
