Colpocoryphe is a genus of trilobites in the family Calymenidae.

Morphology

 * Convex Cephalon
 * Trapezoidal glabellae, frequently distinctly furrowed and surelevated compared to the axis.
 * Dorsal furrows slightly convergent forwardly with almost linear anterior parts.
 * Broad dorsal furrows, deep and not well defined.
 * 3, rather 4, well defined lateral furrows


 * Librigenæ without lateral area or lateral furrow.
 * Preglabellar field very short, downward oriented.
 * Inflated occipital ring with smooth lateral ends.
 * Occipital furrow broad and deep.
 * Eye ridges rather weak.
 * Anterior cephalic notch marked, with frequently parallel edges.
 * Thorax : Strongly convex axis.
 * Triangular Pygidium
 * Convex axis, with segmentation well defined.
 * 6 - 8 axial rings.
 * Pleurae with deep border furrows.
 * Axis extending nearly to posterior margin (large posterior terminal piece), connected to
 * it by short postaxial ridge.


 * Pleural fields behind articulating half-ribs nearly smooth, with 2 - 3 very indistinct ribs.
 * Wide border distinctly set off by marked change in convexity.
