Compsaraia samueli may be further distinguished from C. compsa by secondary sexual dimorphisms in several features of snout and jaw morphology (Ref. 80384). Albert, J.S. and W.G.R.

In the Iquitos region, the type series, which included sexually mature males and females, was collected during the periods of rising and high water (January–April). This corresponds with the typical pattern of apteronotids to breed during the early rising water phase (Crampton, 1996, 1998) (Ref. 80384). Albert, J.S. and W.G.R.
