Diagnosis. The forewing length is 7.0–9.0 mm in males and 9.0–10.0 mm in females. Siccia durantei is externally indistinguishable from S. setis , S. spinulosia , S. microsticta , S. curvalva , and S. stictica , and identification requires the examination of the genitalia structures. The male genital capsule of the new species is reminiscent of S. microsticta but distinguished by the more elongate and distally tapered distal section of the valva, which is broadly elliptical in the congener. The phalli and the vesicae of the two species display no remarkable differences. In the female genitalia, the new species is distinguished from S. microsticta by the markedly denser postero-lateral setose clusters of the ductus and ostium bursae. Additionally, the corpus bursae of S. durantei bears more robust spinulose scobination than in the congener.

Molecular data. The intraspecific divergence of COI-5P sequences calculated from five sampled specimens is in the range of 0.00–0.77%. The nearest neighbours of S. durantei are S. microsticta and S. curvalva differing by 2.52–3.49% and 4.46–4.97%, respectively.

Distribution. The new species is currently known from Gabon and Republic of the Congo. Etymology. The species is dedicated to Mr Antonio Durante (Natural History Museum of Salento,

Calimera, Italy), specialist in West African Arctiinae . The name is a noun in the genitive case.
