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.
