Minicryphaeus is a genus of trilobite, that lived during the Pragian in what is today Morocco (Anti-Atlas).

The most forward lobe of the central raised area of the cephalon (or glabella) is diamond shaped.

The eye has 5–8 lenses per vertical row (or dorso-ventral file).

The 4 or 5 pairs of lateral pygidial spines (or lappets) are shorter than the area outside the axis (or pleural region) is wide, and they are mainly connected to the posterior pleural bands.

The main differences are that in Minicryphaeus the genal spines are about 75% of the length of the glabella, the spaces between the lateral pygidial lappets are V-shaped, and the terminal spine is triangular and longer than the other lappets.
