Diagnosis. The forewing length is 6.0–7.0 mm in males and 6.0– 6.5 mm in females. Siccia tridens is externally reminiscent of S. pallens but distinguished by the smaller size and the less elongate forewing. The male genital capsules of the two species are similar but the uncus of S. tridens bears three spines apically whereas it is somewhat apically dilated bearing three broad triangular lobes in S. pallens . Additionally, the valva of the new species is somewhat proximally broader than in S. tridens , its cucullus is slightly longer, and the ventral margin of the ventral costal lobe bears more robust spinules. The phalli of the two species are alike. The vesica of S. tridens differs from S. pallens in the somewhat broader and more heavily granulose main chamber, the basally broader and somewhat more elongate subbasal diverticulum, and the longer distal diverticulum. Compared to S. pallens , the female genitalia of S. tridens have a markedly broader antrum, a longer and broader corpus bursae bearing stronger spinulose scobination, and a proximally broader appendix bursae.

Molecular data. The intraspecific divergence of COI-5P sequences calculated from two sampled specimens is 0.31%. As the molecular data are currently unavailable for the most similar S. pallens , the COI- 5P sequences of S. tridens were compared with S. robusta , from which the current new species diverges by 3.64%.

Distribution. The new species is currently known from north-western Ivory Coast, Togo, Nigeria and northern Cameroon.

Etymology. In Latin, ‘tridens’ means ‘trident’. The specific epithet refers to the uncus bearing three spines apically. The name is a noun in the nominative singular in apposition.
