Diagnosis

♂♂ 14-15mm.#

The facies is very much paler than in typical corbetti, the pale grey of the ground only lightly irrorated with darker scales and some yellowish ones. The fasciae and small marginal spots are evident as ground colour without irroration, and the black discal spot is conspicuous.

The genitalia show no differences from those of the holotype of corbetti.
