Remarks. (1) Birket-Smith (1965) described duplicata as a species distinct from A. tryphosa based on the difference in the proximal lobes of the distal saccular processes: “It [ A. tryphosa ] differs from both A. similis n. sp. and A. duplicata n. sp. in the male genitalia by having the basal pointed process of valva bent mesad near its base, the bend being slightly swollen, knee-like”. However, the shape of the proximal lobe of the distal saccular process including the width of its base is variable in Archithosia species including A. tryphosa , and the angle at which it is bent in A. tryphosa depends on the way the valvae are spread and pressed by the cover slip. Reliable recognisable genital differences between duplicata and tryphosa are minor therefore duplicata is herein downgraded to a subspecies of tryphosa . (2) The female genitalia of the ‘allotype’ illustrated by Birket- Smith (1965: fig. 17) belong to A. pervolgata sp. n.

Diagnosis. The forewing length is 11.5–13.0 mm in males and 12.5–14.0 mm in females. In the male genitalia, A. t. duplicata differs from the nominate subspecies by the shorter distal diverticulum. The distal saccular process of A. t. duplicata is usually somewhat longer than in A. t. tryphosa (noticeably exceeding the tip of the dorsal section of the valva) but the holotype of the latter has a similarly long process while some of the dissected specimens of A. t. duplicata have equally short processes like those of A. t. tryphosa . Thus, the length of the distal saccular process cannot be accepted as a reliable diagnostic feature between the two taxa. The female genitalia of the two subspecies display no remarkable differences.

Distribution. The subspecies is widely distributed from Ziama Massif in the west to the western Congo Basin in the east, and is currently known from Guinea, Liberia, Ivory Coast, Nigeria, Cameroon, Gabon, and Republic of Congo.
