 Diagnosis. The forewing length is 8.5–10.0 mm in males and 9.5–11.0 mm in females. Siccia nzame is externally very similar to S. kota, S. akanthodis and S. bicultula, and identification requires the examination of the genitalia structures. The male genital capsule of S. nzame is similar to the aforementioned species but distinguished by the two short but thick medial-ventral processes of the ventral lobe of the costa whereas the processes are markedly longer in the similar species. Additionally, in the new species, the ventral lobe of the cucullus is basally broader than in S. kota and S. akanthodis, and the distal lobe of the cucullus is longer than in S. akanthodis and S. bicultula. The phallus of S. nzame is markedly shorter and narrower than in the similar species (in proportion to the tegumen-vinculum complex). The vesica of the new species is shorter than in the similar congeners and has a shorter subbasal dorsal diverticulum. The female genitalia of S. nzame can be distinguished from other members of the species-group by the large triangular ventral sclerotised lobes of the ostium bursae, the narrower posterior plate of the ductus bursae, the anterior section of the ductus bursae lacking the spinulose scobination medially, and the considerably shorter and narrower corpus bursae with a shorter signum. Additionally, the lateral subostial lobes of the new species are more elongate than in the similar congeners, and the appendix bursae is proximally narrower.   
 Molecular data. The intraspecific divergence of COI-5P sequences calculated from three sampled specimens is in the range of 0.00–0.77%. The genetically next-closest species is S. akanthodis differing by 6.14–6.84%.   
 Distribution. The new species is currently known from Gabon, Republic of the Congo, and Democratic Republic of the Congo.   
 Etymology. In the mythologies of the Fang people of Equatorial Guinea, Gabon, and Cameroon, Nzame is the supreme creator god. The name is a noun in the nominative singular in apposition.
