The central raised area of the cephalon (or glabella) is somewhat tapering forward, generally with 3 or 4 pairs of more or less distinct lateral furrows.

The front of the glabella is rounded or truncate, and is separated from the border by a wide, moderately convex to flat (or rarely concave) so-called preglabellar field.

The fracture lines (or sutures) that in moulting separate the fixed from the free cheeks (fixigenae and librigenae) may converge or diverge in front of eyes.

Behind the eyes they cut the posterior margin of the cephalon inside the inner bend of the genal spine (or opisthoparian sutures).

Alokistocarids have a relatively large articulating middle part of the body (or thorax), consisting of 12 to 19 segments.
