I have never seen this species, or at least this color morph, before. I can tell from the telson structure that it is in the family Protosquillidae. My guess is that it is a member of the specious genus Haptosquilla, but this one is new to me. If it dies, you decide to get rid of it, I would appreciate if you would send it to me. I very well could be a new species.
