Remarks. The examined type of Macrosiagon signaticollis var. usambarensis is identical with the type of Macrosiagon signaticollis and both taxa are synonymised. Macrosiagon signaticollis is, however, very similar to M. ferruginea and may represent only its variety (pronotal disc black or orange with black longitudinal stripes, elytra shorter in comparison with the pronotum; possible allometry).

Distribution. An Afrotropical species described from Benin and Tanzania. It is recorded here from Burundi, Democratic Republic of the Congo, Guinea and Uganda for the first time.
