This is overlaid with a series dark inverted chevron-like crossbars that run down the back, similar to C. defilippii and C. rhombeatus.

[7] C. resimus is found in Central and eastern Africa from Nigeria east to Sudan, Uganda, Ethiopia, Kenya, Somalia, and south to Tanzania, Rwanda, Burundi, and Democratic Republic of the Congo.

The type locality is listed as "Sennâr, vom Gebel-Ghule" (Jebel Ghule, Sennar, Sudan).

[2] The preferred natural habitats of C. resimus are low-lying moist savanna, wooded hills, high grasslands, and the riparian zones of rivers that run through swamps, rocky gorges, coastal scrubland, and semi-deserts.

It is also known to occur in man-made habitats, such as abandoned quarries, sugar cane plantations, and in borrow pit pools along roads.

The front part of the body is raised and coiled, from which position it tends to make sweeping and lashing strikes as opposed to a stabbing motion.
