Diagnosis. The forewing length is 7.0–8.0 mm in males and 8.5 mm in the female. Siccia duodecimpunctata mikrotera externally differs from the nominate subspecies in the markedly smaller size and the less elongate forewing apex. The male genitalia of the new subspecies are very similar to S. duodecimpunctata duodecimpunctata but the uncus is somewhat thicker. In the female genitalia of S. duodecimpunctata mikrotera , the posterior half of the corpus bursae is covered with larger spinules than in the nominate subspecies.

Molecular data. The intrasubspecific divergence of COI-5P sequences calculated from nine sampled specimens is in the range of 0.00–1.24%. The pairwise distance between S. duodecimpunctata mikrotera and S. acornuta is in the range of 1.56–3.32%.

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

Etymology. The subspecific epithet is derived from the Greek ‘μικρότερος’ meaning ‘smaller’ and refers to its smaller size in comparison to the nominate subspecies. The name is a noun in the nominative singular in apposition.
