Diagnosis. The forewing apex of this species is less falcate than the other species in this group. It is also distinguishable from other species by the orange ground colour, the small and indistinct spots on the upperside of both wings, the faint pale brown patches near the lower angle of the cell on the forewing with only slightly darker center spots, and the absence of the forewing apical patch. This species is close to T. finita in the male genitalia, but can be differentiated by the following features: the eighth tergite is nearly quadrate in T. fulva , but ampullate in T. finita ; the bundle of spines of the cornuti in T. fulva is thinner than that in T. finita .
