Diagnosis. The forewing length is 6.0–7.0 mm in males and 7.0–8.0 mm in females. The new species differs externally from the other members of the group in the smaller spots of the forewing pattern and, compared to S. synthetia and S. kastanota , the paler greyish-brown hindwing. The male genital capsule of S. carinata differs clearly from the other species in the group in the considerably broader valva. The phallus of the new species bears a single upcurved dorsal carinal process whereas S. conicarina has two carinal processes directed dorsally and ventrally, and three carinal processes are present in S. synthetia and S. kastanota , namely a thorn-like dorsal one, a plate-like, distally directed ventral one, and a lateral crescentshaped serrulate lateral plate. The vesica of S. carinata is semiglobular, similar to that of S. conicarina but broader with a shorter and broader ventral diverticulum, and lacking a distal diverticulum. Since the females of the other species in the group are unknown, the female genitalia of S. carinata were compared with the morphologically most similar S. taprobanis species-group. The ductus bursae of S. carinata is markedly shorter than in the members of the aforementioned group, and curved sideways with a laterally protruding right side (it is more or less straight in the S. taprobanis species-group). The corpus bursae of the new species is small (markedly shorter than the ovipositor), globular, lacking signa but densely covered with minute spinules whereas in the S. taprobanis species-group, the corpus bursae is larger and subdivided into an elongate posterior and globular anterior sections with the latter one bearing one or two signa but lacking the spinulose scobination.

Molecular data. The intraspecific divergence of COI-5P sequences calculated from 11 sampled specimens is in the range of 0.00–3.14%. Siccia carinata diverges from S. conicarina and S. synthetia by 8.32–9.71% and 5.78–8.21%, respectively.

Distribution. The new species is known from Guinea, Liberia, Ivory Coast and Gabon.

Etymology. The specific epithet refers to the robust, upcurved dorsal carinal process characteristic of the species. The name is a noun in the nominative singular in apposition.
