Diagnosis. The forewing length is 14.0– 15.5 mm in males and 16.5–17.5 mm in females. Architesma ampullaria sp. n. is externally very similar to A. frondosa sp. n. and A. makomensis sensu Birket-Smith (1965) (illustrated by Krüger 2015: figs 37, 38, 218, 320) and reliable identification requires the examination of the genitalia structures, which are considerably different in many aspects in all three species. The male genitalia structure of A. ampullaria sp. n. is most similar to A. sordida and A. bassa sp. n. and the detailed comparison with the latter species is provided below in its diagnosis. Unlike in A. sordida , the male genital capsule of A. ampullaria sp. n. has a markedly longer dorsal section of the valva with a longer editum-costa complex bearing a longer, distally narrowed distal ampulla with a foot-shaped and slightly upcurved spinulose tip whereas the ampulla of A. sordida is short, straight and thumb-shaped. The sacculus of A. ampullaria sp. n. is shorter than in A. sordida and bears shorter basal, and shorter and proximally narrower distal processes. The phalluses of the two species are similar but that of A. ampullaria sp. n. is somewhat shorter and narrower than in A. sordida and has a somewhat longer ventral carina. Compared to A. sordida , the vesica of A. ampullaria sp. n. has a narrower proximal section with a somewhat shorter and semiglobular dorsal diverticulum (it is conical in its congener), and a slightly shorter and narrower distal diverticulum. As the female of A. sordida remains unknown, the female genitalia of A. ampullaria sp. n. were compared with A. bassa sp. n. instead (see below in the diagnosis of the latter). Besides A. bassa sp. n., the female genitalia of A. ampullaria sp. n. are also similar to A. henricus (illustrated by Durante et al. 2024), from which A. ampullaria sp. n. differs in the shorter postvaginal formation having a narrow and shallow V-shaped posterior incision (vs. a broad and U-shaped depression in A. henricus ) and shorter, narrower and less swollen lateral plates, and the remarkably longer, broader and semi-rounded antevaginal plate, which is broader than the postvaginal formation (in A. henricus the antevaginal plate is trapezoidal with rounded corners and is narrower than the postvaginal formation).

Distribution. The new species is known from Sierra Leone, Guinea, Liberia and Ivory Coast.

Etymology. The specific epithet refers to the long editum of the new species bearing a large ampulla protruding beyond the valvula tip. The name is a noun in the nominative singular in apposition.
