Diagnosis. The forewing length is 12.5–14.0 mm in males and 13.5–16.0 mm in females. Architesma ndoki sp. n. is morphologically most similar to the sympatric A. dolgomoides sp. n. and the detailed comparison is provided below in the diagnosis of the latter species. Among other species in the genus Architesma , the sympatric A. nouabaleana sp. n. is also reminiscent of A. ndoki sp. n. but the former is larger and has a somewhat broader forewing with a slightly straighter costal margin and a more distally prominent medial curve of the transverse line. The male genitalia of A. ndoki sp. n. are clearly different from A. nouabaleana sp. n. in their distally longer uncus, the more apically tapered valvula, the broader ampulla directed ventrad (it is directed distad in the congener), the distally narrower sacculus with a short, nearly straight, triangular and apically rounded tip (whereas it has a claw-shaped, downcurved tip in A. nouabaleana sp. n.), the longer phallus with a narrower coecum, and the broader distal diverticulum bearing a shorter, thorn-shaped terminal cornutus, which is rather claw-shaped with a plate-like base in A. nouabaleana sp. n. The male genitalia configuration of A. ndoki sp. n. is also reminiscent of A. turlini sp. n. but the latter species can be easily distinguished by its elongate ampulla, the longer sacculus with a thorn-shaped, upcurved tip, the phallus having a downcurved coecum and a larger subdistal ventral protrusion, and the narrower distal diverticulum bearing a smaller terminal cornutus. The female genitalia of A. ndoki sp. n. differ from A. nouabaleana sp. n. in the narrower postvaginal formation with broader and setose swollen lateral plates (they are smooth in the congener), the narrower and shorter postvaginal plate, the more weakly scobinate posterior section of the corpus bursa, and the somewhat larger signum bursae. Additionally, unlike in A. nouabaleana sp. n., the 7 th sternite of A. ndoki sp. n. lacks the postero-lateral sclerotisations. Compared to A. turlini sp. n., A. ndoki sp. n. has markedly longer apophyses anteriores, the anteriorly narrower postvaginal formation with nearly straight lateral margins (they are convex in A. turlini sp. n.) and broader and more heavily setose lateral swollen plates, and the shorter and narrower antevaginal plate with a more convex posterior margin.

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

Etymology. The specific epithet refers to the type locality of the new species, Nouabalé-Ndoki National Park. The name is a noun in the nominative singular in apposition.
