Diagnosis.

Closely resembles Tessmannella roberti and Tessmannella copelandi in having the medial area of the forewing hyaline; distinguished from these species by having two distinct infuscate patches on the forewing. This species is further distinguished by the very distinctive wave-like texturing of the cuticle on the lateral aspects of the pronotum (areolate in other species of Tessmannella ).

Etymology.

Named in honor of Rudyard Kipling, author of Just So Stories and others about Africa.
