How identified?
I'm not familiar with West Coast amphipods but I'll make a species page.

ID
It's immature so I'm going off the "T-shaped" opposed to "butterfly shaped" dorsal pigment and the two versus three diffuse spots on the sides. With the pigmentation on the side occurring on coxa 6 & 7.

What source did you use for the ID? I don't have any for the region so it would be helpful for identifying future submissions to BG.
