Kanohi Question

There’s a Ta-Matoran in the comic “Death of a Hero” with a mask I don’t recognize, nor do I believe BioSector01 has any information on. Here’s a picture:

Strange Ta-Matoran

My questions is simple: What is that mask? Is it one of the masks with an unknown appearance, like the Pehkui or the Mask of Healing, or is it just a odd rendering of a mask we already know?
