 Description of adult (Figure 3D)   
Wingspan 24–31 mm. Head white, labial palpus clothed with white scales above, brown on outer side, terminal segment bent slightly downwards; flagellum fuscous becoming paler towards base, scape white. Thorax white, tegulae brown, metathorax with a pair of coremata pointing obliquely inwards. Fore wing costa chocolate-brown, a broad white vitta from base to apex, small black spots on lower edge at one-third and two-thirds, beneath it a chocolate-brown streak widening towards termen, dorsal streak white; a row of black dashes along termen, cilia white except grey below apex. Hind wing fuscous, becoming paler basally and white towards costa. Abdomen white mixed with pale fuscous. Legs pale fulvous, tibia of hindleg clothed with white hairs, tibiae of foreleg and midleg with fuscous scales.  
This species differs from other Olethreutinae in its large size and very distinctive fore wing markings with the white vitta separating brown areas along costa and dorsum.  
 Male genitalia (Figure 7). Uncus paired, strongly bent downwards; valva reduced to a long, narrow, curved, digitate process; sacculus large, very three-dimensional, slightly asymmetrical with a large pointed process near base and a process with two similar flaps apically; aedeagus strongly curved without cornutus.   
 Female genitalia (Figure 8). Ostium wide and strong, signa comprising two angled plates, one of them tapering.   
 Larva (Figure 1E)   
Head black, prothoracic plate black with a white central division. Body white with an orange band around each segment, a subdorsal row of brown spots on the anterior part of each segment, a similar row of brown spots beneath it on the posterior part of each segment, a row of larger brown spots sublaterally, each on the anterior side of the orange ring; thoracic legs brownish, anal plate black.  
 Lives within a domatium of Acacia drepanolobium, often within a brown silken tube.   
Pupa wings blackish, body brown. Emerges through a circular “trapdoor” in the wall of the domatium.  
 Distribution   
Kenya, Tanzania.  
 Derivation   
 From the Latin vitta meaning a band.
