(ANHRT).   
 Diagnosis. The forewing length is 8.0–9.0 mm in males and 10.0 mm in the female. Siccia alberti is externally reminiscent of large specimens of S. microsticta, S. durantei, and S. curvalva and identification requires the examination of the genitalia structures. The male genital capsule of the new species is most similar to S. imana, from which S. alberti is distinguished by the more elongate valva, the shorter and broader, hook-like curved cucullus (it is triangular in S. imana), and the broader tip of the distal saccular process bearing considerably longer setae. The phallus of the new species is distally narrower than in the similar congener. Compared to S. imana, the vesica of S. alberti is narrower (in proportion to the phallus width), and bears thinner and more numerous cornuti. In the female genitalia, the new species is distinguished from S. imana by the longer ovipositor, the longer, narrower and loop-like curved proximal section of the lateral subostial lobe (it is trapezoidal in S. imana), the shorter and broader ductus bursae, and the markedly broader corpus bursae covered with more robust spinules. The detailed comparison with another similar species, S. takanoi is provided below in the diagnosis of this species.   
 Molecular data. Currently unavailable for this species.   
 Distribution. The new species is known from Gabon and Republic of the Congo.   
 Etymology. The new species is dedicated to Mr Jean-Louis Albert (Libreville, Gabon), passionate entomologist and one of the collectors of the holotype, for acknowledging his significant contribution to the knowledge of the insect fauna of Gabon.
