Diagnosis. The forewing length is 10.0–11.0 mm in males and 10.5–11.5 mm in females. Siccia kota is externally very similar to S. nzame , S. akanthodis and S. bicultula , and identification requires the examination of the genitalia structures. The male genital capsule of the new species is similar to S. nzame and S. bicultula but distinguished from the former species by the somewhat shorter valva (in proportion to the tegumen-vinculum complex length), the shorter cucullus with narrower lobes, and the presence of only the outer medial-ventral process of the ventral costal lobe, which is longer and thinner than in S. nzame . Additionally, compared to S. nzame , the juxta of S. kota is broader and bearing two small postero-sublateral triangular processes, and the uncus is longer. The phallus of S. kota is longer and broader than in S. nzame . The vesica of the new species is longer than in S. nzame and has a longer subbasal dorsal diverticulum. In the female genitalia, S. kota differs from S. nzame in the markedly shorter and narrower ventral sclerotised lobes of the ostium bursae directed posteriorly (they are directed latero-posteriorly in the congener), the broader ductus bursae with a shorter but broader posterior plate and dense spinulose scobination anteriorly, the considerably longer and broader corpus bursae with a longer signum, and the proximally broader appendix bursae. Additionally, the lateral subostial lobes of S. kota are remarkably shorter than in S. nzame .

Molecular data. The intraspecific divergence of COI-5P sequences calculated from three sampled specimens is in the range of 0.00–0.93%. The nearest neighbours of S. kota are S. bicultula and S. akanthodis differing by 5.47–6.50% and 5.48–5.65%, respectively.

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

Etymology. The species is named after the Kota people, a Bantu ethnic group from Gabon and Republic of the Congo. The name is a noun in the nominative singular in apposition.
