It was initially erected as a subgenus of Phacops but some later authors thought it distinctive enough to raise its status.

Chotecops is the most abundant trilobite in the Hunsrück Slate and due to the excellent preservation, often soft tissue such as antennae and legs have been preserved as a thin sheet of pyrite.

Like in all sighted Phacopina, the eyes of Chotecops are compounded of very large, separately set lenses without a common cornea (so called schizochroal eyes), and like almost all other Phacopina, the articulate mid-length part of the body (or thorax) in Chotecops has 11 segments.

The central raised area of the cephalon (called glabella) consists from back to front of an occipital ring, but unlike in its close relative Phacops the preoccipital ring in Chotecops is flat and not reduced to its sides, and the furrow defining its front (S1) is shallow.

The large frontal lobe is moderately vaulted and falls steeply to the furrow that defines the border at its front.
