Diagnosis. The forewing length is 7.0– 8.5 mm in males and 9.0–10.0 mm in females. Siccia processa chloma is externally distinguished from the nominate subspecies in the larger size, the more elongate and somewhat paler forewing, and the markedly paler hindwing. However, the male genitalia of the two subspecies display no remarkable differences. In the female genitalia, the new subspecies differs from the nominate one in the more elongate lateral subostial lobes.

Molecular data. The intrasubspecific divergence of COI-5P sequences calculated from five specimens is in the range of 0.00–0.62%. The pairwise distance between the two subspecies of S. processa is in the range of 0.93–1.56%.

Distribution. The new subspecies is known from Gabon, Republic of the Congo and Democratic Republic of the Congo.

Etymology. The subspecific epithet is derived from the Greek ‘χλωμός’ meaning ‘pale’ and refers to the paler colouration of the wings in comparison to the nominate subspecies. The name is a noun in the nominative singular in apposition.
