Kuamaia is an extinct genus of marine Cambrian arthropod belonging to Conciliterga, which is part of the broader group Artiopoda (which contains trilobites and their close relatives).

[4] A spiny section on K. lata's legs is presumed to have allowed it to tear apart food.

K. lata appears smooth, with little space between tergites and low-profile pleural spines.

The head bore a pair of eyes, with the optic lobes of these extending into the anterior sclerite.

The antennae of Kuamaia lata were modified from their sensory function in other artiopods, into grasping raptorial appendages, similar to those of Kiisortoqia, suggesting it was an active predator.
