Diagnosis. The forewing length is 14.0–16.0 mm in males and 16.5–17.5 mm in females. Architesma nouabaleana sp. n. is externally reminiscent of A. henricus , A. frondosa sp. n. and A. ampullaria sp. n. and identification requires examination of the genitalia structures. The male genital capsule of A. nouabaleana sp. n. is most similar to A. henricus and A. diffusa sp. n. but distinguished from the former by the broader uncus, the broader dorsal section of the valva with a longer and broader editum-costa complex with a somewhat more prominent, swollen ampulla, and the broader sacculus with a thicker basal process and a shorter, proximally broader but distally thinner distal process. Compared to A. diffusa sp. n., A. nouabaleana sp. n. has a broader uncus, a broader dorsal section of the valva with a broader editum-costa complex, and a shorter and distally narrower sacculus with a somewhat shorter basal process and a markedly shorter but proximally thicker distal process. The phallus of A. nouabaleana sp. n. has a straighter ventral wall than in the aforementioned congeners and has a shorter ventral carina than in A. diffusa sp. n. In the vesica, A. nouabaleana sp. n. differs from both these species in the shorter distal diverticulum bearing a thinner cornutus, and the somewhat shorter dorsal diverticulum. The female genitalia of A. nouabaleana sp. n. are most similar to A. diffusa sp. n. but distinguished by the trapezoidal postvaginal formation (it is pentagonal in its congener) with narrower swollen lateral plates, the more weakly sclerotised antevaginal plate, the broader posterior section of the corpus bursae, and the somewhat larger signum bursae. Additionally, the postero-lateral sclerotisations of the 7 th sternite of A. nouabaleana sp. n. are somewhat broader than in A. diffusa sp. n. Compared to A. henricus (illustrated by Durante et al. 2024: fig. 8A), the female genitalia of A. nouabaleana sp. n. have longer apophyses anteriores, a trapezoidal postvaginal formation with narrower and less arcuate lateral plates, a short and triangular antevaginal plate protruding posteriorly (whereas it is broader, trapezoidal and protruding anteriorly in the congener), and a posteriorly narrower posterior section of the corpus bursae having a markedly smaller appendix bursae. The postero-lateral sclerotisations of the 7 th sternite of A. nouabaleana sp. n. are broader than in A. henricus .

Distribution. The new species is currently known from north-eastern Republic of Congo.

Etymology. The specific epithet is derived from Nouabalé-Ndoki National Park, where the new species is found. The name is a noun in the nominative singular in apposition.
