 Note. In the original description of the species, Hampson (1914) mentioned a male and two females from Kumasi as “Type”. In order to stabilise the nomenclature, the male syntype is hereby designated as the lectotype.   
 Diagnosis. The forewing length is 7.0– 8.5 mm in males and 9.5–11.0 mm in females. Siccia gypsia is externally reminiscent of species of the S. setis and the S. microsticta species-groups but differs in the less elongate and more rounded forewing apex, the larger spots in the cell, and the weaker blackish suffusion on the forewing. The male genitalia of S. gypsia are distinguished from the other species in the genus by the medially constricted valva lacking processes and having a narrow and elliptical cucullus, and the juxta structure, which is unique in the genus. In S. gypsia, the juxta is broad, heavily sclerotised bearing two postero-lateral thorn-like processes and two strongly elongate band-shaped and weakly sclerotised parallel postero-medial processes fused with the anellus and supporting the phallus ventrally whereas in most other species in Siccia, the juxta is smaller, weakly sclerotised and lacking processes. In the female genitalia, the structure of the elongate and relatively narrow antrum is characteristic of the species: it has heavily sclerotised and swollen lateral margins medially and anteriorly separated from each other by the flexible, finely cellulate longitudinal medial area. The detailed comparison with the similar S. ankistro is provided below in the diagnosis of the latter species.   
 Molecular data. The intraspecific divergence of COI-5P sequences calculated from 10 sampled specimens is in the range of 0.00–0.62%. The pairwise distance between S. gypsia and the similar S. ankistro is in the range of 3.65–3.98%.   
 Distribution. The species is known from Guinea, Liberia, Sierra Leone, Ivory Coast, Ghana, Nigeria, Cameroon, Gabon, Republic of the Congo, Democratic Republic of the Congo, and Uganda. The record from western Kenya (Kühne 2008) requires clarification as the only specimen from this area available for examination in the present study belongs to S. ankistro, which is externally indistinguishable from S. gypsia.
